OOP Structure for web application

- by Query

Ok so I have a website in which users complete tasks to earn points. When they earn enough points, they rise in rank. The site from my understanding is very basic and only executes one query or two queries at most a page. There is a user table, a support ticket table, and an orders table. All of these contain a relational row for username. Our class was familiarized with OOP back in highschool with Java but that was for video games and I could grasp the concept on why you would need a class player and class enemy. However I don't understand it's web application. At least not in my situation. I understand the user class might contain stuff like: getUsername getPoints getEmail setEmail addPoints (does this belong here? OR only things the user can manipulate should be here?) etc.. But I'm at a loss with everything else such as user registration. Can you help give me a wire framework that I could wrap my head around? Pointing me to a good eBook would help greatly

Need to include Calendar and Email in own CRM system. Whose?

- by PurplePilot

I am writing a web based application that needs to have some elements of CRM in it but I cannot use an of-the-shelf CRM to do what I want. (Honestly we have been through it all and it will not work). Now while Tasks, Calls, Meetings and Notes are straightforward the idea of reinventing Mail and Calendars seems a waste of time and effort and also unproductive as most users already have their own and it simply adds to the complexity of my application and hacks users off. My thoughts are going around using Outlook and or GMail/iCal and or Mac Mail/iCal and or Thunderbird and importing the relevant data or if possible integrating it into the application. Any thoughts? Anyone got any experience of this can point me in a few directions. N.B. Not looking for an answer as too complex just some pointers and thoughts. Thanks. p.s. We did look at Sugar CRM as the basis for our project and it is useful to get best practice from but as I say it was not useable due to how we are structuring our software, not Sugar's fault.

Scala - learning by doing

- by wrecked

coming from the PHP-framework symfony (with Apache/MySQL) I would like to dive into the Scala programming language. I already followed a few tutorials and had a look at Lift and Play. Java isn't a stranger to me either. However the past showed that it's easiest to learn things by just doing them. Currently we have a little - mostly ajax-driven - application build on symfony at my company. My idea is to just build a little project similar to this one which might gets into production in the future. The app should feature: High scalability and performance a backend-server web-interface and a GUI-client There are plenty of questions arising when I think of this. First of all: Whats the best way to accomplish a easy to maintain, structured base for it? Would it be best to establish a socket based communication between pure-scala server/client and accessing that data via Lift or is building a Lift-app serving as a server and connecting the gui-client (via REST?) the better way? Furthermore I wounder which database to choose. I'm familiar with (My)SQL but feel like a fool beeing confronted with all these things like NoSQL, MongoDB and more. Thanks in advance!

Working for a company vs starting my own? [closed]

- by Mark

I need some advice, I am considering going to grad school for CS. I have a few big projects I came up with on my own that I am extremely motivated to work on and complete and try to turn it into a career. I am currently completing an internship working for a big company, decent pay, 9-5 hours in an office. I feel like working for the same company many people would enjoy and like, is extremely boring in my opinion and procedural at times and kills my motivation. As a result, I am kind of unsure if I should continue to get my CS M.S. degree and start working for a big company? What I would enjoy doing most is working for myself and developing my own project, but I am not sure if I will be able to finanically support myself doing that and I do not want to miss out on a big opportuinities/ job offers to work for a company. With that being said, I will never know if my project will ever succeed if I don't give it %110 of my time and dedication, so if I decide to go that route and work on my own project, I will have to set everything else aside, If anyone could give me any advice on what they think about my situation?

PHP hosting some info required [closed]

- by mtk

I have recently given a control of newly bought hosting space and the domain account. There is a technical team from the hosting site to help out with problems, but that is a long process, i.e. log a ticket, wait for a long time, and I don't get the correct answer in the first shot. I was wondering, if anyone has any helpful guide and how one must go with hosting a site. Any info that must be know w.r.t to cpanel? Any other useful stuff if any one has, or could point me to ? Just to give a few difficulties: The same php code working well on local machine, giving error on remote as "File not found". The file is present indeed as I have ftp'ed all the files correctly. session_start error are outputted to html page with warning "Header already sent". and many more technical things, that work well on local but not on actual hosting server. So, if anyone has any helpful stuff in this reference, as to what all changes are required or what a programmer must be aware from a hosting perspective, please let me know. Note I am hosting a PHP site with mysql db, on a shared environment.

To program in free time as a programmer, is to show that programming is passion. If not, is the programmer good? [closed]

- by SonofWatson

Possible Duplicate: I don't program in my spare time. Does that make me a bad developer? A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

- by w3softdev

this question has re-posted by me in the following group if you find suitable to answer this question then please click on the link attached here or copy paste this in your browser.. http://answers.onstartups.com/questions/32767/which-technology-or-strategy-a-new-inexperienced-freelancer-should-use-to-earn Well it is my very first Question in this section and i really don't know whether my query relate to this section or not. anyway i have some awkward query. (however, it is like a bit story but i guess it is necessary to know some background knowledge of me.) Actually I m fresh recent grad who has just started his freelancing work. In due course i have got a project to develop website for a middle scale business (travel agent). As I don't trust on my client whether he will pay to me in full or not after the completion of website, i want to use cheaper and efficient technology so that how much he would pay I could got at least few units of % of profit. As i have learnt ASP.NET and when I inquired about the expense in Hosting of my website i got the recommendation to develop my web app using the combination PHP and MYSQL instead the asp.net + ms sql. And the problem is I don't know PHP. should I learn PHP and or work in what i m comfortable with and should try to cover whole deserved money. (as it is my first project so i m also advised that i may got some loss in starting but contrary to this i don't want to go in loss and want to earn appropriate profit)

Phishing attack stuck with jsp loginAction.do page? [closed]

- by user970533

I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

I am being paid very little(imo), how can I change this? [migrated]

- by LagWagon

I am a web developer with about 4 years of relevant work experience in my field. Recently, I went from making $30/hr working from home contracting for large companies to a full time job that only pays 40k/yr. The company I work for now is great, nice people, but a little behind the times. I joined on with very little experience in SQL development but they put me in charge of querying the DB and making reports right away, so I had to go in head first and pick up that skill right away. Which is great, I'm happy I learned more of that, and really make good time when doing SQL now. However, I'm now doing most of their advanced SQL stuff. The day I started, another employee who was running a MVC project based in Yii (which is the sole item that makes this company software) put in his two weeks. Two weeks later, I'm the only one who knows how to use, access, modify, or update this project. Its quite a large responsibility for an "entry level dev", no? I am doing highly advanced jQuery for them to modernize their forms, webpages, amongst other things, a skill that I would bet on few Entry levels being able to do as well as me. I may be wrong, but I feel that what I'm making now is not acceptable. We don't have reviews, ever, so I can't just wait for that.. so I was wondering.. do I sound justified in wanting to be paid more, and how can I make this happen?

Google and Bing Map APIs Compared

- by SGWellens

At one of the local golf courses I frequent, there is an open grass field next to the course. It is about eight acres in size and mowed regularly. It is permissible to hit golf balls there—you bring and shag our own balls. My golf colleagues and I spend hours there practicing, chatting and in general just wasting time. One of the guys brings Ginger, the amazing, incredible, wonder dog. Ginger is a Portuguese Pointer. She chases squirrels, begs for snacks and supervises us closely to make sure we don't misbehave. Anyway, I decided to make a dedicated web page to measure distances on the field in yards using online mapping services. I started with Google maps and then did the same application with Bing maps. It is a good way to become familiar with the APIs. Here are images of the final two maps: Google: Bing: To start with online mapping services, you need to visit the respective websites and get a developers key. I pared the code down to the minimum to make it easier to compare the APIs. Google maps required this CSS (or it wouldn't work): <style type="text/css"> html { height: 100%; } body { height: 100%; margin: 0; padding: 0; } Here is how the map scripts are included. Google requires the developer Key when loading the JavaScript, Bing requires it when the map object is created: Google: <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=XXXXXXX&libraries=geometry&sensor=false" > </script> Bing: <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"> </script> Note: I use jQuery to manipulate the DOM elements which may be overkill, but I may add more stuff to this application and I didn't want to have to add it later. Plus, I really like jQuery. Here is how the maps are created: Common Code (the same for both Google and Bing Maps): <script type="text/javascript"> var gTheMap; var gMarker1; var gMarker2; $(document).ready(DocLoaded); function DocLoaded() { // golf course coordinates var StartLat = 44.924254; var StartLng = -93.366859; // what element to display the map in var mapdiv = $("#map_div")[0]; Google: // where on earth the map should display var StartPoint = new google.maps.LatLng(StartLat, StartLng); // create the map gTheMap = new google.maps.Map(mapdiv, { center: StartPoint, zoom: 18, mapTypeId: google.maps.MapTypeId.SATELLITE }); // place two markers marker1 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng + .0001)); marker2 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng - .0001)); DragEnd(null); } Bing: // where on earth the map should display var StartPoint = new Microsoft.Maps.Location(StartLat, StartLng); // create the map gTheMap = new Microsoft.Maps.Map(mapdiv, { credentials: 'Asbsa_hzfHl69XF3wxBd_WbW0dLNTRUH3ZHQG9qcV5EFRLuWEaOP1hjWdZ0A0P17', center: StartPoint, zoom: 18, mapTypeId: Microsoft.Maps.MapTypeId.aerial }); // place two markers marker1 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng + .0001)); marker2 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng - .0001)); DragEnd(null); } Note: In the Bing documentation, mapTypeId: was missing from the list of options even though the sample code included it. Note: When creating the Bing map, use the developer Key for the credentials property. I immediately place two markers/pins on the map which is simpler that creating them on the fly with mouse clicks (as I first tried). The markers/pins are draggable and I capture the DragEnd event to calculate and display the distance in yards and draw a line when the user finishes dragging. Here is the code to place a marker: Google: // ---- PlaceMarker ------------------------------------ function PlaceMarker(location) { var marker = new google.maps.Marker( { position: location, map: gTheMap, draggable: true }); marker.addListener('dragend', DragEnd); return marker; } Bing: // ---- PlaceMarker ------------------------------------ function PlaceMarker(location) { var marker = new Microsoft.Maps.Pushpin(location, { draggable : true }); Microsoft.Maps.Events.addHandler(marker, 'dragend', DragEnd); gTheMap.entities.push(marker); return marker; } Here is the code than runs when the user stops dragging a marker: Google: // ---- DragEnd ------------------------------------------- var gLine = null; function DragEnd(Event) { var meters = google.maps.geometry.spherical.computeDistanceBetween(marker1.position, marker2.position); var yards = meters * 1.0936133; $("#message").text(yards.toFixed(1) + ' yards'); // draw a line connecting the points var Endpoints = [marker1.position, marker2.position]; if (gLine == null) { gLine = new google.maps.Polyline({ path: Endpoints, strokeColor: "#FFFF00", strokeOpacity: 1.0, strokeWeight: 2, map: gTheMap }); } else gLine.setPath(Endpoints); } Bing: // ---- DragEnd ------------------------------------------- var gLine = null; function DragEnd(Args) { var Distance = CalculateDistance(marker1._location, marker2._location); $("#message").text(Distance.toFixed(1) + ' yards'); // draw a line connecting the points var Endpoints = [marker1._location, marker2._location]; if (gLine == null) { gLine = new Microsoft.Maps.Polyline(Endpoints, { strokeColor: new Microsoft.Maps.Color(0xFF, 0xFF, 0xFF, 0), // aRGB strokeThickness : 2 }); gTheMap.entities.push(gLine); } else gLine.setLocations(Endpoints); } Note: I couldn't find a function to calculate the distance between points in the Bing API, so I wrote my own (CalculateDistance). If you want to see the source for it, you can pick it off the web page. Note: I was able to verify the accuracy of the measurements by using the golf hole next to the field. I put a pin/marker on the center of the green, and then by zooming in, I was able to see the 150 markers on the fairway and put the other pin/marker on one of them. Final Notes: All in all, the APIs are very similar. Both made it easy to accomplish a lot with a minimum amount of code.

WCF WS-Security and WSE Nonce Authentication

- by Rick Strahl

WCF makes it fairly easy to access WS-* Web Services, except when you run into a service format that it doesn't support. Even then WCF provides a huge amount of flexibility to make the service clients work, however finding the proper interfaces to make that happen is not easy to discover and for the most part undocumented unless you're lucky enough to run into a blog, forum or StackOverflow post on the matter. This is definitely true for the Password Nonce as part of the WS-Security/WSE protocol, which is not natively supported in WCF. Specifically I had a need to create a WCF message on the client that includes a WS-Security header that looks like this from their spec document:<soapenv:Header> <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsse:UsernameToken wsu:Id="UsernameToken-8" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsse:Username>TeStUsErNaMe1</wsse:Username> <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >TeStPaSsWoRd1</wsse:Password> <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >f8nUe3YupTU5ISdCy3X9Gg==</wsse:Nonce> <wsu:Created>2011-05-04T19:01:40.981Z</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> Specifically, the Nonce and Created keys are what WCF doesn't create or have a built in formatting for. Why is there a nonce? My first thought here was WTF? The username and password are there in clear text, what does the Nonce accomplish? The Nonce and created keys are are part of WSE Security specification and are meant to allow the server to detect and prevent replay attacks. The hashed nonce should be unique per request which the server can store and check for before running another request thus ensuring that a request is not replayed with exactly the same values. Basic ServiceUtl Import - not much Luck The first thing I did when I imported this service with a service reference was to simply import it as a Service Reference. The Add Service Reference import automatically detects that WS-Security is required and appropariately adds the WS-Security to the basicHttpBinding in the config file:<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="RealTimeOnlineSoapBinding"> <security mode="Transport" /> </binding> <binding name="RealTimeOnlineSoapBinding1" /> </basicHttpBinding> </bindings> <client> <endpoint address="https://notarealurl.com:443/services/RealTimeOnline" binding="basicHttpBinding" bindingConfiguration="RealTimeOnlineSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> </configuration> If if I run this as is using code like this:var client = new RealTimeOnlineClient(); client.ClientCredentials.UserName.UserName = "TheUsername"; client.ClientCredentials.UserName.Password = "ThePassword"; … I get nothing in terms of WS-Security headers. The request is sent, but the the binding expects transport level security to be applied, rather than message level security. To fix this so that a WS-Security message header is sent the security mode can be changed to: <security mode="TransportWithMessageCredential" /> Now if I re-run I at least get a WS-Security header which looks like this:<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:Timestamp u:Id="_0"> <u:Created>2012-11-24T02:55:18.011Z</u:Created> <u:Expires>2012-11-24T03:00:18.011Z</u:Expires> </u:Timestamp> <o:UsernameToken u:Id="uuid-18c215d4-1106-40a5-8dd1-c81fdddf19d3-1"> <o:Username>TheUserName</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> Closer! Now the WS-Security header is there along with a timestamp field (which might not be accepted by some WS-Security expecting services), but there's no Nonce or created timestamp as required by my original service. Using a CustomBinding instead My next try was to go with a CustomBinding instead of basicHttpBinding as it allows a bit more control over the protocol and transport configurations for the binding. Specifically I can explicitly specify the message protocol(s) used. Using configuration file settings here's what the config file looks like:<?xml version="1.0"?> <configuration> <system.serviceModel> <bindings> <customBinding> <binding name="CustomSoapBinding"> <security includeTimestamp="false" authenticationMode="UserNameOverTransport" defaultAlgorithmSuite="Basic256" requireDerivedKeys="false" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"> </security> <textMessageEncoding messageVersion="Soap11"></textMessageEncoding> <httpsTransport maxReceivedMessageSize="2000000000"/> </binding> </customBinding> </bindings> <client> <endpoint address="https://notrealurl.com:443/services/RealTimeOnline" binding="customBinding" bindingConfiguration="CustomSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration> This ends up creating a cleaner header that's missing the timestamp field which can cause some services problems. The WS-Security header output generated with the above looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-291622ca-4c11-460f-9886-ac1c78813b24-1"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> This is closer as it includes only the username and password. The key here is the protocol for WS-Security:messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" which explicitly specifies the protocol version. There are several variants of this specification but none of them seem to support the nonce unfortunately. This protocol does allow for optional omission of the Nonce and created timestamp provided (which effectively makes those keys optional). With some services I tried that requested a Nonce just using this protocol actually worked where the default basicHttpBinding failed to connect, so this is a possible solution for access to some services. Unfortunately for my target service that was not an option. The nonce has to be there. Creating Custom ClientCredentials As it turns out WCF doesn't have support for the Digest Nonce as part of WS-Security, and so as far as I can tell there's no way to do it just with configuration settings. I did a bunch of research on this trying to find workarounds for this, and I did find a couple of entries on StackOverflow as well as on the MSDN forums. However, none of these are particularily clear and I ended up using bits and pieces of several of them to arrive at a working solution in the end. http://stackoverflow.com/questions/896901/wcf-adding-nonce-to-usernametoken http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/4df3354f-0627-42d9-b5fb-6e880b60f8ee The latter forum message is the more useful of the two (the last message on the thread in particular) and it has most of the information required to make this work. But it took some experimentation for me to get this right so I'll recount the process here maybe a bit more comprehensively. In order for this to work a number of classes have to be overridden: ClientCredentials ClientCredentialsSecurityTokenManager WSSecurityTokenizer The idea is that we need to create a custom ClientCredential class to hold the custom properties so they can be set from the UI or via configuration settings. The TokenManager and Tokenizer are mainly required to allow the custom credentials class to flow through the WCF pipeline and eventually provide custom serialization. Here are the three classes required and their full implementations:public class CustomCredentials : ClientCredentials { public CustomCredentials() { } protected CustomCredentials(CustomCredentials cc) : base(cc) { } public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager() { return new CustomSecurityTokenManager(this); } protected override ClientCredentials CloneCore() { return new CustomCredentials(this); } } public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager { public CustomSecurityTokenManager(CustomCredentials cred) : base(cred) { } public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version) { return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11); } } public class CustomTokenSerializer : WSSecurityTokenSerializer { public CustomTokenSerializer(SecurityVersion sv) : base(sv) { } protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); // in this case password is plain text // for digest mode password needs to be encoded as: // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password)) // and profile needs to change to //string password = GetSHA1String(nonce + createdStr + userToken.Password); string password = userToken.Password; writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } protected string GetSHA1String(string phrase) { SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider(); byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase)); return Convert.ToBase64String(hashedDataBytes); } } Realistically only the CustomTokenSerializer has any significant code in. The code there deals with actually serializing the custom credentials using low level XML semantics by writing output into an XML writer. I can't take credit for this code - most of the code comes from the MSDN forum post mentioned earlier - I made a few adjustments to simplify the nonce generation and also added some notes to allow for PasswordDigest generation. Per spec the nonce is nothing more than a unique value that's supposed to be 'random'. I'm thinking that this value can be any string that's unique and a GUID on its own probably would have sufficed. Comments on other posts that GUIDs can be potentially guessed are highly exaggerated to say the least IMHO. To satisfy even that aspect though I added the SHA1 encryption and binary decoding to give a more random value that would be impossible to 'guess'. The original example from the forum post used another level of encoding and decoding to string in between - but that really didn't accomplish anything but extra overhead. The header output generated from this looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-f43d8b0d-0ebb-482e-998d-f544401a3c91-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">ThePassword</o:Password> <o:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >PjVE24TC6HtdAnsf3U9c5WMsECY=</o:Nonce> <u:Created>2012-11-23T07:10:04.670Z</u:Created> </o:UsernameToken> </o:Security> </s:Header> which is exactly as it should be. Password Digest? In my case the password is passed in plain text over an SSL connection, so there's no digest required so I was done with the code above. Since I don't have a service handy that requires a password digest, I had no way of testing the code for the digest implementation, but here is how this is likely to work. If you need to pass a digest encoded password things are a little bit trickier. The password type namespace needs to change to: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest and then the password value needs to be encoded. The format for password digest encoding is this: Base64(SHA-1(Nonce + Created + Password)) and it can be handled in the code above with this code (that's commented in the snippet above): string password = GetSHA1String(nonce + createdStr + userToken.Password); The entire WriteTokenCore method for digest code looks like this:protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); string password = GetSHA1String(nonce + createdStr + userToken.Password); writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } I had no service to connect to to try out Digest auth - if you end up needing it and get it to work please drop a comment… How to use the custom Credentials The easiest way to use the custom credentials is to create the client in code. Here's a factory method I use to create an instance of my service client: public static RealTimeOnlineClient CreateRealTimeOnlineProxy(string url, string username, string password) { if (string.IsNullOrEmpty(url)) url = "https://notrealurl.com:443/cows/services/RealTimeOnline"; CustomBinding binding = new CustomBinding(); var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement(); security.IncludeTimestamp = false; security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256; security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10; var encoding = new TextMessageEncodingBindingElement(); encoding.MessageVersion = MessageVersion.Soap11; var transport = new HttpsTransportBindingElement(); transport.MaxReceivedMessageSize = 20000000; // 20 megs binding.Elements.Add(security); binding.Elements.Add(encoding); binding.Elements.Add(transport); RealTimeOnlineClient client = new RealTimeOnlineClient(binding, new EndpointAddress(url)); // to use full client credential with Nonce uncomment this code: // it looks like this might not be required - the service seems to work without it client.ChannelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>(); client.ChannelFactory.Endpoint.Behaviors.Add(new CustomCredentials()); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; return client; } This returns a service client that's ready to call other service methods. The key item in this code is the ChannelFactory endpoint behavior modification that that first removes the original ClientCredentials and then adds the new one. The ClientCredentials property on the client is read only and this is the way it has to be added. Summary It's a bummer that WCF doesn't suport WSE Security authentication with nonce values out of the box. From reading the comments in posts/articles while I was trying to find a solution, I found that this feature was omitted by design as this protocol is considered unsecure. While I agree that plain text passwords are rarely a good idea even if they go over secured SSL connection as WSE Security does, there are unfortunately quite a few services (mosly Java services I suspect) that use this protocol. I've run into this twice now and trying to find a solution online I can see that this is not an isolated problem - many others seem to have struggled with this. It seems there are about a dozen questions about this on StackOverflow all with varying incomplete answers. Hopefully this post provides a little more coherent content in one place. Again I marvel at WCF and its breadth of support for protocol features it has in a single tool. And even when it can't handle something there are ways to get it working via extensibility. But at the same time I marvel at how freaking difficult it is to arrive at these solutions. I mean there's no way I could have ever figured this out on my own. It takes somebody working on the WCF team or at least being very, very intricately involved in the innards of WCF to figure out the interconnection of the various objects to do this from scratch. Luckily this is an older problem that has been discussed extensively online and I was able to cobble together a solution from the online content. I'm glad it worked out that way, but it feels dirty and incomplete in that there's a whole learning path that was omitted to get here… Man am I glad I'm not dealing with SOAP services much anymore. REST service security - even when using some sort of federation is a piece of cake by comparison :-) I'm sure once standards bodies gets involved we'll be right back in security standard hell…© Rick Strahl, West Wind Technologies, 2005-2012Posted in WCF Web Services Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

Best development architecture for a small team of programmers

- by Tio

Hi all.. I'm in the first month of work in a new company.. and after I met the two programmer's and asked how things are organized in terms of projects inside the company, they simply shrug their shoulders, and said that nothing is organized.. I think my jaw hit the ground that same time.. ( I know some, of you think I should quit, but I'm on a privileged position, I'm the most experienced there, so there's room for me to grow inside the company, and I'm taking the high road ).. So I talked to the IT guy, and one of the programmers, and maybe this week I'm going to get a server all to myself to start organizing things. I've used various architectures in my previous work experiences, on one I was developing in a server on the network ( no source control of course ).. another experience I had was developing in my local computer, with no server on the network, just source control. And at home, I have a mix of the two, everything I code is on a server on the network, and I have those folders under source control, and I also have a no-ip account configured on that server so I can access it everywhere and I can show the clients anything. For me I think this last solution ( the one I have at home ) is the best: Network server with LAMP stack. The server as a public IP so we can access it by domain name. And use subdomains for each project. Everybody works directly on the network server. I think the problem arises, when two or more people want to work on the same project, in this case the only way to do this is by using source control and local repositories, this is great, but I think this turns development a lot more complicated. In the example I gave, to make a change to the code, I would simply need to open the file in my favorite editor, make the change, alter the database, check in the changes into source control and presto all done. Using local repositories, I would have to get the latest version, run the scripts on the local database to update it, alter the file, alter the database, check in the changes to the network server, update the database on the network server, see if everything is running well on the network server, and presto all done, to me this seems overcomplicated for a change on a simple php page. I could share the database for the local development and for the network server, that sure would help. Maybe the best way to do this is just simply: Network server with LAMP stack ( test server so to speak ), public server accessible trough the web. LAMP stack on every developer computer ( minus the database ) We develop locally, test, then check in the changes into the server test and presto. What do you think? Maybe I should start doing this at home.. Thanks and best regards...

The Work Order Printing Challenge

- by celine.beck

One of the biggest concerns we've heard from maintenance practitioners is the ability to print and batch print work order details along with its accompanying attachments. Indeed, maintenance workers traditionally rely on work order packets to complete their job. A standard work order packet can include a variety of information like equipment documentation, operating instructions, checklists, end-of-task feedback forms and the likes. Now, the problem is that most Asset Lifecycle Management applications do not provide a simple and efficient solution for process printing with document attachments. Work order forms can be easily printed but attachments are usually left out of the printing process. This sounds like a minor problem, but when you are processing high volume of work orders on a regular basis, this inconvenience can result in important inefficiencies. In order to print work order and its related attachments, maintenance personnel need to print the work order details and then go back to the work order and open each individual attachment using the proper authoring application to view and print each document. The printed output is collated into a work order packet. The AutoVue Document Print Service products that were just released in April 2010 aim at helping organizations address the work order printing challenge. Customers and partners can leverage the AutoVue Document Print Services to build a complete printing solution that complements their existing print server solution with AutoVue's document- and platform-agnostic document print services. The idea is to leverage AutoVue's printing services to invoke printing either programmatically or manually directly from within the work order management application, and efficiently process the printing of complete work order packets, including all types of attachments, from office files to more advanced engineering documents like 2D CAD drawings. Oracle partners like MIPRO Consulting, specialists in PeopleSoft implementations, have already expressed interest in the AutoVue Document Print Service products for their ability to offer print services to the PeopleSoft ALM suite, so that customers are able to print packages of documents for maintenance personnel. For more information on the subject, please consult MIPRO Consulting's article entitled Unsung Value: Primavera and AutoVue Integration into PeopleSoft posted on their blog. The blog post entitled Introducing AutoVue Document Print Service provides additional information on how the solution works. We would also love to hear what your thoughts are on the topic, so please do not hesitate to post your comments/feedback on our blog.

What are the options for hosting a small Plone site? [closed]

- by Tina Russell

Possible Duplicate: How to find web hosting that meets my requirements? I’ve developed a portfolio website for myself using Plone 4, and I’m looking for someplace to host it. Most Plone hosting services seem to focus on large, corporate deployments, but I need something that I can afford on a very limited budget and fits a small, single-admin website. My understanding is that my basic options are thus: I can go with a hosting service that specifically provides Plone. I know of WebFaction, but what others exist? Also, I’d have two stipulations for a Plone hosting service: (a) It needs to use Plone 4, for which I’ve developed my site, and (b) it needs to allow me SSH access to a home directory (including the Plone configuration), so that I may use my custom development eggs and such. I could use a VPS hosting service. What are my options here? Again, I need something cheap and scaled to my level. I could use Amazon EC2 or a similar service (please tell me of any) and pay by the tiniest unit of data. I’m a little scared of this because I have no idea how to do a cost-benefit analysis between this and a regular VPS host. The advantage of this approach would be that I only pay for what I use, making it very scalable, but I don’t know how the overall cost would compare to any VPS host under similar circumstances. What factors enter into the cost of Amazon EC2? What can I expect to pay under either option for regular traffic for a new website? Which one is more desirable for when a rush of visitors drive up my bandwidth bill? One last note: I know Plone isn’t common for websites for individuals, but please don’t try to talk me out of it here; that’s a completely different subject. For now, assume I’m sticking with Plone for good. Also, I have seen the Plone hosting services list on Plone.org—it’s twenty pages long, and the first page was nothing but professional Plone consulting services that sometimes offer hosting for business clients. So, that wasn’t much help. Thank you!

In the Cloud, Everything Costs Money

- by BuckWoody

I’ve been teaching my daughter about budgeting. I’ve explained that most of the time the money coming in is from only one or two sources – and you can only change that from time to time. The money going out, however, is to many locations, and it changes all the time. She’s made a simple debits and credits spreadsheet, and I’m having her research each part of the budget. Her eyes grow wide when she finds out everything has a cost – the house, gas for the lawnmower, dishes, water for showers, food, electricity to run the fridge, a new fridge when that one breaks, everything has a cost. She asked me “how do you pay for all this?” It’s a sentiment many adults have looking at their own budgets – and one reason that some folks don’t even make a budget. It’s hard to face up to the realities of how much it costs to do what we want to do. When we design a computing solution, it’s interesting to set up a similar budget, because we don’t always consider all of the costs associated with it. I’ve seen design sessions where the new software or servers are considered, but the “sunk” costs of personnel, networking, maintenance, increased storage, new sizes for backups and offsite storage and so on are not added in. They are already on premises, so they are assumed to be paid for already. When you move to a distributed architecture, you'll see more costs directly reflected. Store something, pay for that storage. If the system is deployed and no one is using it, you’re still paying for it. As you watch those costs rise, you might be tempted to think that a distributed architecture costs more than an on-premises one. And you might be right – for some solutions. I’ve worked with a few clients where moving to a distributed architecture doesn’t make financial sense – so we didn’t implement it. I still designed the system in a distributed fashion, however, so that when it does make sense there isn’t much re-architecting to do. In other cases, however, if you consider all of the on-premises costs and compare those accurately to operating a system in the cloud, the distributed system is much cheaper. Again, I never recommend that you take a “here-or-there-only” mentality – I think a hybrid distributed system is usually best – but each solution is different. There simply is no “one size fits all” to architecting a solution. As you design your solution, cost out each element. You might find that using a hybrid approach saves you money in one design and not in another. It’s a brave new world indeed. So yes, in the cloud, everything costs money. But an on-premises solution also costs money – it’s just that “dad” (the company) is paying for it and we don’t always see it. When we go out on our own in the cloud, we need to ensure that we consider all of the costs.

Basic web architecture : Perl -> PHP

- by Sunny Jim

This is an architecture question. If there is a better forum, please redirect me. Apologies in advance. Essentially every website is built around a relational database, right? When a user uploads form data, that data is stored in a table. The problem is that the table structure(s) need to be modified whenever the website form is modified. Although I understand that modern web frameworks work around this problem by automatically building forms based on the table structure. For the last 20 years, I have been building websites using Perl. When I first encountered this problem, the easiest solution was to save serialized Perl objects as data BLOBS. After XML's introduction, this solution worked even better because XML is so effective for representing arbitrary data. This approach is consistent with the original Perl principles of Hubris, Laziness, and Impatience and I'm pretty committed to it. Obviously, the biggest drawback is that this solution locks me into the Perl interpreter. So instead, I've just completed a prototype of a universal RDB table. The prototype is written in Perl but porting it to PHP will be a good chance to develop those skills. The principal is based on the XML::Dumper module, which converts arbitrary Perl data structures into uniform XML. With my approach, each XML node is stored as a table record. I underestimated this undertaking and rolled something up myself. But the effort allows me to discuss the basic design instead of implementation details. As mentioned, I'm pretty committed to this approach of using flexible data structures. It's been successfully deployed on many websites, large, and complex. But are there any drawbacks I've overlooked? I rolled my own. Are other people taking a similar approach to their data? What kinds of solutions are available? I have not abandoned my dream of eventually contributing something useful to the worldwide community. In order to proceed, the next step would be peer review. How does one pursue that effort? Thanks! -Jim

Implementation shows the way to consume web service using jQuery. The client side AJAX with HTTP POST request is significant when it comes to loading speed and responsiveness.Following is the service created that return's string in JSON.[WebMethod][ScriptMethod(ResponseFormat = ResponseFormat.Json)]public string getData(string marks){ DataTable dt = retrieveDataTable("table", @" SELECT * FROM TABLE WHERE MARKS='"+ marks.ToString() +"' "); List<object> RowList = new List<object>(); foreach (DataRow dr in dt.Rows) { Dictionary<object, object> ColList = new Dictionary<object, object>(); foreach (DataColumn dc in dt.Columns) { ColList.Add(dc.ColumnName, (string.Empty == dr[dc].ToString()) ? null : dr[dc]); } RowList.Add(ColList); } JavaScriptSerializer js = new JavaScriptSerializer(); string JSON = js.Serialize(RowList); return JSON;}Consuming the webservice $.ajax({ type: "POST", data: '{ "marks": "' + val + '"}', // This is required if we are using parameters contentType: "application/json", dataType: "json", url: "/dataservice.asmx/getData", success: function(response) { RES = JSON.parse(response.d); var obj = JSON.stringify(RES); } error: function (msg) { alert('failure'); }});Remember to reference jQuery library on the page.

How important is knowing functionality before coding?

- by minusSeven

I work for a software development company where the development work have been off shored to us. The on shore team handle the support and talk directly to the clients. We never talk to the clients directly we just talk people from the on shore team who talk directly to the clients. When requirements come, on shore team talk to the clients and make requirement documents and informs us. We make design documents after studying the requirements (we follow traditional waterfall model ). But there is one problem in the whole process: nobody in the either off-shore or on-shore understand the functionality of the application completely. We just know its a big complex web app handling complex order processing, catalog management, campaign management and other activities. We struggle with the design document as the requirements would not be clear. It then goes into a series of questions/answers back and forth between the on shore team,off shore team and clients. We would often be told to understand functionality from the code. But that's usually not feasible as the code base is huge and even understanding a simple menu item take days if not weeks. We tried telling the clients to give us knowledge transfer about the application but to no avail. Our manager would often tell us to start coding even if the design document is not complete or requirements not clear. We would start by coding part of the requirement that seems clear and wait for the rest. This usually would delay the deployment by a month. In extreme cases we would have very low errors in the development and production but the clients would say that's not what they asked. That would start a blame game and a series of change requests and we would end up developing something very different. My question is how would you do development work if you don't know the functionality of the app fully? UPDATE About development methodology it isn't really my choice and I am not my team's lead It is the way it began. I tried to tell people about the advantages of agile but to no avail. Besides I don't think my team has the necessary mindset to work in AGILE environment.

Responsive Design for your ADF Faces Web Applications

- by Shay Shmeltzer

Responsive web applications are a common pattern for designing web pages that adjust their UI based on the device that access them. With the increase in the number of ADF applications that are being accessed from mobile phones and tablet we are getting more and more questions around this topic. Steven Davelaar wrote a comprehensive article covering key concepts in this area that you can find here. The article focuses on what I would refer to as server adaptive application, where the server adapts the UI it generates based on the device that is accessing the server. However there is one more technique that is not covered in that article and can be used with Oracle ADF - it is CSS manipulation on the client that can achieve responsive design. I'll cover this technique in this blog entry. The main advantage of this technique is that the UI manipulation does not require the server to send over a new UI when a change is needed. This for example allows your page to change immediately when you change the orientation of your device. (By the way this example was developed for one of the seminars in the upcoming Oracle ADF OTN Virtual Developer Day). In the demo that you'll see below you'll see a single page that changes the way it is displayed based on the orientation of the device. Here is the page with the tablet in landscape and portrait: To achieve this I'm using a CSS media query in my page template that changes the display property of a couple of style classes that are used in my page. The media query has this format: @media screen and (max-width:700px) { .narrow { display: inline; } .wide { display: none; } .adjustFont { font-size: small; } .icon-home { font-size: 24px; } } This changes the properties of the same styleClasses that are defined in my application's skin. Here is a quick demo video that shows you the full application and explains how it works. For those looking to replicate this, here are the basic files: skin1.css @charset "UTF-8";/**ADFFaces_Skin_File / DO NOT REMOVE**/@namespace af "http://xmlns.oracle.com/adf/faces/rich";@namespace dvt "http://xmlns.oracle.com/dss/adf/faces";.wide { display: inline;}.narrow { display: none;}.adjustFont { font-size: large;}.icon-home { font-family: 'UIShellUGH'; -webkit-font-smoothing: antialiased; font-size: 36px; color: #ffa000;} pageTemplate: <?xml version='1.0' encoding='UTF-8'?><af:pageTemplateDef xmlns:af="http://xmlns.oracle.com/adf/faces/rich" var="attrs" definition="private" xmlns:afc="http://xmlns.oracle.com/adf/faces/rich/component"> <af:xmlContent> <afc:component> <afc:description>A template that will work on phones and desktop</afc:description> <afc:display-name>ResponsiveTemplate</afc:display-name> <afc:facet> <afc:facet-name>main</afc:facet-name> </afc:facet> </afc:component> </af:xmlContent> <meta name="viewport" content="width=device-width, initial-scale=1"/> <af:resource type="css">@media screen and (max-width:700px) { .narrow { display: inline; } .wide { display: none; } .adjustFont { font-size: small; } .icon-home { font-size: 24px; } }@font-face { font-family: 'UIShellUGH'; src: url(data:application/x-font-woff;charset=utf-8;base64,d09GRk9UVE8AA..removed code here...AzV6b1g==)format('truetype'); font-weight: normal; font-style: normal; } </af:resource> <af:panelGroupLayout id="pt_pgl4" layout="vertical" styleClass="sizeStyle"> <af:panelGridLayout id="pt_pgl1"> <af:gridRow marginTop="5px" height="40px" id="pt_gr1"> <af:gridCell marginStart="5px" width="100%" marginEnd="5px" id="pt_gc1"> <af:panelGroupLayout id="pt_pgl3" halign="center" layout="horizontal"> <af:outputText value="h" id="ot2" styleClass="icon-home"/> <af:outputText value="HR System" id="ot3" styleClass="adjustFont"/> </af:panelGroupLayout> </af:gridCell> </af:gridRow> <af:gridRow marginTop="5px" height="auto" id="pt_gr2"> <af:gridCell marginStart="5px" width="100%" marginEnd="5px" id="pt_gc2" halign="stretch"> <af:panelGroupLayout id="pt_pgl2" layout="scroll"> <af:facetRef facetName="main"/> </af:panelGroupLayout> </af:gridCell> </af:gridRow> <af:gridRow marginTop="5px" height="20px" marginBottom="5px" id="pt_gr3"> <af:gridCell marginStart="5px" width="100%" marginEnd="5px" id="pt_gc3"> <af:panelGroupLayout id="pt_pgl5" layout="vertical" halign="center"> <af:separator id="pt_s1"/> <af:outputText value="Copyright Oracle Corp. 2013" id="pt_ot1" styleClass="adjustFont"/> </af:panelGroupLayout> </af:gridCell> </af:gridRow> </af:panelGridLayout> </af:panelGroupLayout></af:pageTemplateDef> Example from the page: <af:gridRow id="gr3"> <af:gridCell id="gc7" columnSpan="2"> <af:panelGroupLayout id="pgl8" styleClass="narrow"> <af:link text="Menu" id="l1"> <af:showPopupBehavior triggerType="action" popupId="p1" align="afterEnd"/> </af:link> </af:panelGroupLayout> <af:panelGroupLayout id="pgl7" styleClass="wide"> <af:navigationPane id="np1" hint="buttons"> <af:commandNavigationItem text="Departments" id="cni1"/> <af:commandNavigationItem text="Employees" id="cni2"/> <af:commandNavigationItem text="Salaries" id="cni3"/> <af:commandNavigationItem text="Jobs" id="cni4"/> <af:commandNavigationItem text="Services" id="cni5"/> <af:commandNavigationItem text="Support" id="cni6"/> <af:commandNavigationItem text="Help" id="cni7"/> </af:navigationPane> </af:panelGroupLayout> </af:gridCell> </af:gridRow>
