  • chat application: pubsubhubbub vs xmpp

    - by sofia
    I'm unsure on the best stack to build a chat application. Currently I'm thinking of two main options: facebook tornado cons: does not use the main chat protocol xmpp but pubsubhubbub pros: i really like its simplicity for development (webserver + webframework); pubsubhubbub also seems simpler as a protocol than xmpp; and i know python xmpp + bosch, punjab, ejabberd cons: don't know erlang; overall seems a bit harder to develop pros: uses xmpp protocol The chat app will need to have the following: Private messages Public rooms Private rooms Chat history for rooms (not forever, just the last n messages) html embedding url to chat room Both options seem scalable so that's not really my worry (we're thinking of running the app in amazon's ec2 as well). I know there's a project that builds a xmpp server using tornado but it's not ready for production use and our deadline isn't that big. Basically my main worry is ease of development vs somehow regretting later using pubsubhubbub to develop a chat app but I read somewhere that PubSubHubbub might eventually replace XMPP as REST replaced SOAP - so what do you think?

  • Dealing with the lack of closures in Objective-C

    - by Sean Clark Hess
    Maybe it's just the fact that I've been using http://nodejs.org/ lately, but the lack of closures in Objective-C (iphone) has been really hard to work around. For example, I'm creating service classes. Each service class can have several methods, each of which makes a different URL request. I can use the delegate pattern, but that means that I have to create a new service each time I want to call a method on it (because it has to store the delegate and selector for that request, and new method calls would overwrite them). Even more difficult for me is the fact that I can't easily keep local variables around in the scope for a callback. I have to store anything I want to send back to the delegate on the service class itself, which makes it harder to have more than one method on each class. How do you pros do it? Should I just quit whining and do it another way?

  • How to return model state from child action handler in ASP.NET MVC

    - by Joe Future
    In my blog engine, I have one controller action that displays blog content, and in that view, I call Html.RenderAction(...) to render the "CreateComment" form. When a user posts a comment, the post is handled by the comment controller (not the blog controller). If the comment data is valid, I simply return a Redirect back to the blog page's URL. If the comment data is invalid (e.g. comment body is empty), I want to return the ViewData with the error information back to the blog controller and through the blog view to the CreateComment action/view so I can display which fields are bad. I have this working fine via AJAX when Javascript is enabled, but now I'm working on the case where Javascript might be disabled. If I return a RedirecToAction or Redirect from the comment controller, the model state information is lost. Any ideas?

  • java httpclient post

    - by Eric V
    Hi, I have a question about how to allow my jsp page to issue a post command to the server, and still have the browser fallow the re direction of the posted page. Here are the code snipets: code that does the post (this is inside a jsp file): HttpClient client = new DefaultHttpClient(); client.getParams().setParameter("SUBMITTED", "submitted"); client.getParams().setParameter("xxxxxxxx", purchaser.getemail()); client.getParams().setParameter("xxxxxxxx", purchaser.getsuject()); HttpPost method = new HttpPost(url+"process.jsp"); client.execute(method); here is a snipet of process.jsp if (person.getStatus() == person.ACTIVE) response.sendRedirect("Account.jsp); else if (person.getStatus() == person.ERROR) response.sendRedirect("Error.jsp); I would like the browser to the fallow/goto the redirect from the process.jsp. Does anyone know a tutorial that would help me or Am I going about this the wrong way. Thanks, eric

  • Hide header and footer when printing from Internet Explorer using Javascript or CSS

    - by molasses
    When I print a webpage from Internet Explorer it will automatically add a header and footer including the website title, URL, date, and page number. Is it possible to hide the header and footer programatically using Javascript or CSS? Requirements: works in IE 6 (no other browser support necessary as its for an Intranet) may use ActiveX, Java Applet, Javascript, CSS preferably not something that the user needs to install (eg. http://www.meadroid.com/scriptx). feel free to list other third party available plug-ins though as I think this may be the only option don't require the user to manually update their browser settings don't render the pages as PDF or Word document or any other format don't write to the registry (security prevents this) Thanks

  • Poorly performing regex

    - by Kieron
    I've a really poorly performing piece of regex, currently it makes Firefox, Chrome and IE hang for a period of time. Here's the reg-ex: ^([a-zA-Z0-9]+[/]?)+[a-zA-Z0-9]+$ It's kind of a url matcher, but should only match the requested path (not starting with or ending with a slash). Valid examples: Segment Segment/Segment segment/segment/Segment (etc) Invalid examples: /Segment Segment/ Segment/Segment/ Using the regex above over all three browsers and using two or more slashes causes the browsers to hang. It's obviously a poorly formed reg-ex, but can anyone help build a better one? Thanks,

  • OFM 11g: Implementing OAM SSO with Forms

    - by olaf.heimburger
    There is some confusion about the integration of OFM 11g Forms with Oracle Access Manager 11g (OAM). Some say this does not work, some say it works, but.... Actually, having implemented it many times I belong to the later group. Here is how. Caveat Before you start installing anything, take a step back and consider your current implementation and what you really need and want to achieve. The current integration of Forms 11g with OAM 11g does not support self-service account creation and password resets from the Forms application. If you really need this, you must use the existing Oracle AS 10.1.4.3 infrastructure. On the other hand, if your user population is pretty stable, you can enjoy the latest Forms 11g with OAM 11g. Assumptions The whole process should be done in one day. I assume that all domains and instances are started during setup, if you need to restart them on demand or purpose, be sure to have proper start/stop scripts, I don't mention them. Preparation It goes without saying, that you always should do a proper backup before you change anything on your production environment. With proper backup, I also mean a tested and verified restore process. If you dared to test it before, do it now. It pays off. Requirements For OAM 11g to work properly you need a LDAP repository. For the integration of Forms 11g you need an Oracle Internet Directory (OID) configured with the Oracle AS SSO LDAP extensions. For better support I usually give the latest version a try, in this case OID 11g is a good choice.During the Installation and Integration steps we use an upgrade wizard that needs the old OID configuration on the same host but in a different ORACLE_HOME. Installation vs Configuration With OFM 11g Oracle introduced a clear separation between Installation of the binaries (the software) and the Configuration of the instances (the runtime). This is really great as you can install all the software and create new instances when needed. In the following we adhere to this scheme and install the software first and then configure the instances later. Installation Steps The Oracle documentation contains all the necessary steps for the installation of all pieces of software. But some hints help to avoid traps and pitfalls. Step 1 The Database Start the installation with the database. It is quite obvious but we need an Oracle database for all the other steps. If you have one at hand, fine. If not, just install at least a Oracle 10.2.0.4 version. This database can be on a different host. Step 2 The Repository Creation Utility The next step should be to run the Repository Creation Utility (RCU). This is a client application that just needs to connect to your database. It can be run on any host that can reach the database and is a Windows or Linux 32-bit machine. When you run it, be sure to install the OID schema and the OAM schema. If you miss one of these, you can run the RCU again to install the missing schema. Step 3 The Foundation With OFM 11g Oracle started to use WebLogic Server 11g (WLS) as its foundation for all OFM 11g installation. We therefore install it first. Depending on your operating system, it might be possible, that no native installer is available. My approach to this dilemma is to use the WLS Generic Installer for all my installations. It does not include a JDK either but if you have both for your platform you are ready to go. Step 3a The JDK To make things interesting, Oracle currently has two JDKs in its portfolio. The Sun JDK and the JRockit JDK. Both are available for a number of platforms. If you are lucky and both are available for your platform, install both in a separate directory (and not one of your ORACLE_HOMEs) each, You can use the later as you like. Step 3b Install WLS for OID and OAM With the JDK installed, we start the generic installer with java -jar wls_generic.jar.STOP! Before you do this, check the version first. It should be 1.6.0_18 or later and not the GCC one (Some Linux distros have it installed by default). To verify the version, issue a java -version command and make sure that the output does not contain the text gcj and the version matches. If this does not work, use an absolute path like /opt/java/jdk1.6.0_23/bin/java to start the installer. The installer allows you to specify a path to install the software into, say /opt/oracle/iam/11.1.1.3 for the OID and OAM installation. We will call this IAM_HOME. Step 4 Install OID Now we are ready to install OID. Start the OID installer (in the Disk1 directory) and just select the installation only step. This will install the software only and does not configure the instance. Use the IAM_HOME as the target directory. Step 5 Install SOA Suite The IAM 11g Suite uses the BPEL component of the SOA Suite 11g for its workflows. This is a pretty closed environment and not to be used for SCA Composites. We install the SOA Suite in $IAM_HOME/soa. The installer only installs the binaries. Configuration will be done later. Step 6 Install OAM Once the installation of OID and SOA is done, we are ready to install the OAM software in the same IAM_HOME. Make sure to install the OAM binaries in a directory different from the one you used during the OID and SOA installation. As before, we only install the software, the instance will be created later. Step 7 Backup the Installation At this point, I normally do a backup (or snapshot in a virtual image) of the installation. Good when you need to go back to this point. Step 8 Configure OID The software is installed and now we need instances to run it. This process is called configuration. For OID use the config.sh found in $IAM_HOME/oid/bin to start the configuration wizard. Normally this runs smoothly. If you encounter some issues check the Oracle Support site for help. This configuration will also start the OID instance. Step 9 Install the Oracle AS SSO Schema Before we install the Forms software we need to install the Oracle AS SSO Schema into the database and OID. This is a rather dangerous procedure, but fully documented in the IAM Installation Guide, Chapter 10. You should finish this in one go, do not reboot your host during the whole procedure. As a precaution, you should make a backup of the OID instance before you start the procedure. Once the backup is ready, read the chapter, including every note, carefully. You can avoid a number of issues by following all the steps and will succeed with a working solution. Step 10 Configure OAM Reached this step? Great. You are ready to create an OAM instance. Use the $IAM_HOME/iam/common/binconfig.sh for this. This will open the WLS Domain Creation Wizard and asks for the libraries to be installed. You should at least select the OAM with Database repository item. The configuration will also start the OAM instance. Step 11 Install WLS for Forms 11g It is quite tempting to install everything in one ORACLE_HOME. Unfortunately this does not work for all OFM packages. Therefore we do another WLS installation in another ORACLE_HOME. The same considerations as in step 3b apply. We call this one FORMS_HOME. Step 12 Install Forms In the FORMS_HOME we now install the binaries for the Forms 11g software. Again, this is a install only step. Configuration starts with the next step. Step 13 Configure Forms To configure Forms 11g we start the Configuration Wizard (config.sh) in FORMS_HOME/bin. This wizard should create a new WebLogic Domain and an OHS instance! Do not extend existing domains or instances! Forms should run in its own instances! When all information is supplied, the wizard will create the domain and instance and starts them automatically.Step 14 Setup your Forms SSO EnvironmentOnce you have implemented and tested your Forms 11g instance, you can configured it for SSO. Yes, this requires the old Oracle AS SSO solution, OIDDAS for creating and assigning users and SSO to setup your partner applications. In this step you should consider to create every user necessary for use within the environment. When done, do not forget to test it. Step 15 Migrate the SSO Repository Since the final goal is to get rid of the old SSO implementation we need to migrate the old SSO repository into the new OID structure. Additionally, this step will also migrate all partner application configurations into OAM 11g. Quite convenient. To do this step, you have to start the upgrade agent (ua or ua.bat or ua.cmd) on the operating system level in $IAM_HOME/bin. Once finished, this wizard will create new osso.conf files for each partner application in $IAM_HOME/upgrade/temp/oam/.Note: At the time of this writing, this step only works if everything is on the same host (ie. OID, OAM, etc.). This restriction might be lifted in later releases. Step 16 Change your OHS sso.conf and shut down OC4J_SECURITY In Step 14 we verified that SSO for our Forms environment works fine. Now, we are shutting the old system done and reconfigure the OHS that acts as the Forms entry point. First we go to the OHS configuration directory and rename the old osso.conf  to osso.conf.10g. Now we change the moduleconf/mod_osso.conf  to point to the new osso.conf file. Copy the new osso.conf  file from $IAM_HOME/upgrade/temp/oam/ to the OHS configuration directory. Restart OHS, test forms by using the same forms links. OAM should now kick in and show the login dialog to ask for your user credentials.Done. Now your Forms environment is successfully integrated with OAM 11g.Enjoy. What's Next? This rather lengthy setup is just the foundation for your growing environment of OAM 11g protections. In the next entry we will show that Forms 11g and ADF Faces 11g can use the same OAM installation and provide real single sign-on. References Nearly everything is documented. Use the documentation!

  • use jsonp to get xml cross domain

    - by lmkk
    I am trying to read xml into a webpage from another server, and I assume that my problem is Same-Origin Policy, and therefore a cross domain problem. I have a bit of googling and it seems that jsonp is the way forward. Based on some examples I found here on stackoverflow and another sites, this is what I have, and it does not "hit" the server with the xml. I can view the xml in a browser. $(document).ready(function(){ $.ajax({ type: 'GET', dataType: 'jsonp', url: 'http://192.168.0.106:8111/getconfiguration?', success: function (xml) { //do stuff with received xml }}); Any suggestions? please keep in mind that I am a newbie with regards to JS / JQuery ;o)

  • URLEncoding a string with Objective-C

    I'm trying to URL encode a string to form a GET request from objective-c. NSString *params = @"'Decoded data!'/foo.bar:baz"; NSRunAlertPanel( @"Error", [params urlEncoded], @"OK", nil, nil ); This is the category extending NSString -(NSString *) urlEncoded { NSString *encoded = (NSString *)CFURLCreateStringByAddingPercentEscapes( NULL, (CFStringRef)self, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ", kCFStringEncodingUTF8 ); return encoded; } So the first time I run it I get back 1606410046ecoded 1606410784ata2270.000000foo.bar0X1.001716P-1042baz from the dialog box. Immediately after I run it again I get this 1606410046ecoded 1606410944ata227369374562920703448982951250259562309742470533728899744288431318481119278377104028261651081181287077973859930826299575521579020410425419424562236383226511593137467590082636817579938932512039895040.000000foo.bar0X1.66E6156303225P+771baz Then if I run it AGAIN it goes back to the first one. It's really weird. If params is set to @"&" or @" " I just get back a "2" (w/o the quotes) in the dialog box. Also is there a way I can have the % signs be shown in the alert dialog? Thanks

  • Storing file permissions in Subversion repository

    - by graham.reeds
    How do you store file permissions in a repository? A few files need to be read-only to stop a third party program from trashing it but after checking out of the repository they are set to read-write. I looked on google and found a blog post from 2005 that states that Subversion doesn't store file-permissions. There are patches and hook-scripts listed (only one url still exists). Three years later does Subversion still not store file permissions and are hooks the only way to go about this? (I've never done hooks and rather use something that is native to Subversion.)

  • SignalR: hub invokation request

    - by Yuriy Pogrebnyak
    I'm writing custom SignalR client and I need to implement hub invokation. As I understood from .NET client code, I need to send post request to the following url (after establishing connection with server): http://serverurl/signalr/send?transport=serverSentEvents&connectionId=<my_connection_id> . In request body I need to send json string containing basic information about the invoked method. My question is how should this json look like? I'm trying to send smth like this (again, judging by .NET client code): {"data" : {"Hub" : "hubname", "Method" : "methodname", "Args" : {"message" : "msg"} } } But I get the following error: System.ArgumentNullException: Value cannot be null. Parameter name: s. What am I doing wrong? What are required parameters of sending json and how should it be formatted?

  • jQuery .ajax() call to page method works in FF only when async is false

    I'm calling a page method using .ajax() and it works in IE8 whatever the value of async is. However, in FF3.6, it only works with async set to false. When async is set to true, in Firebug, I just see status aborted. The page validates. I can work with async set to false, but any clues as to why FF can't work with async set to true? $("[id$='_www']").click(function() { var hhh = false; $.ajax({ async: false, cache: false, type: "POST", url: "/abc/def.aspx/jkl", contentType: "application/json; charset=utf-8", dataType: "json", data: "{ 'eee': '" + window.location.href.match(/\d{1,3}$/) + "', 'ttt': '" + $("[id$='_zzz']").val() + "' }", success: function(msg) { $("#ggg").html(msg.d); }, error: function(xhr, err) { hhh = true; } }); return hhh; });

  • NSMutableURLRequest not obeying my timeoutInterval

    - by kubi
    I'm POST'ing a small image, so i'd like the timeout interval to be short. If the image doesn't send in a few seconds, it's probably never going to send. For some unknown reason my NSURLConnection is never failing, no matter how short I set the timeoutInterval. // Create the URL request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:0.00000001]; /* Populate the request, this part works fine */ [NSURLConnection connectionWithRequest:request delegate:self]; I have a breakpoint set on - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error but it's never being triggered. My images continue to be posted just fine, they're showing up on Tumblr despite the tiny timeoutInterval.

  • get img src from an img loaded dynamically using jQuery

    - by Lee
    Hey Guys (and Ladies) I am looking at getting the image name from an image with a src loaded dynamically. Basically what I am doing is using the Google chat badge on a site to live chatting. And else where on the page, I have an image saying Live Chat:Online or Live Chat:Offline. And I want this to change depending on whether I am available to chat or not. Does this make sense? Anyway, the easiest way I figure to do this would be check the img url. If the img is offline.gif then obviously I am offline. An example of a dynamically loaded img would be something like <img src="http://www.google.com/talk/service/badge/Show?encrypted_acount_id_here" /> Once this image has loaded, it loads one of the following images "http://www.google.com/talk/service/resources/offlinef.gif" "http://www.google.com/talk/service/resources/idlef.gif" "http://www.google.com/talk/service/resources/onlinef.gif" Hopefully this make sense now. Thanks heaps

  • Remove characters after specific character in string, then remove substring?

    - by sah302
    I feel kind of dumb posting this when this seems kind of simple and there are tons of questions on strings/characters/regex, but I couldn't find quite what I needed (except in another language: http://stackoverflow.com/questions/2176544/remove-all-text-after-certain-point). I've got the following code: [Test] public void stringManipulation() { String filename = "testpage.aspx"; String currentFullUrl = "http://localhost:2000/somefolder/myrep/test.aspx?q=qvalue"; String fullUrlWithoutQueryString = currentFullUrl.Replace("?.*", ""); String urlWithoutPageName = fullUrlWithoutQueryString.Remove(fullUrlWithoutQueryString.Length - filename.Length); String expected = "http://localhost:2000/somefolder/myrep/"; String actual = urlWithoutPageName; Assert.AreEqual(expected, actual); } I tried the solution in the question above (hoping the syntax would be the same!) but nope. I want to first remove the queryString which could be any variable length, then remove the page name, which again could be any length. How can I get the remove the query string from the full URL such that this test passes?

  • Database design for very large amount of data

    - by Hossein
    Hi, I am working on a project, involving large amount of data from the delicious website.The data available is at files are "Date,UserId,Url,Tags" (for each bookmark). I normalized my database to a 3NF, and because of the nature of the queries that we wanted to use In combination I came down to 6 tables....The design looks fine, however, now a large amount of data is in the database, most of the queries needs to "join" at least 2 tables together to get the answer, sometimes 3 or 4. At first, we didn't have any performance issues, because for testing matters we haven't had added too much data in the database. No that we have a lot of data, simply joining extremely large tables does take a lot of time and for our project which has to be real-time is a disaster.I was wondering how big companies solve these issues.Looks like normalizing tables just adds complexity, but how does the big company handle large amounts of data in their databases, don't they do the normalization? thanks

  • regex search a mysql text column

    - by Ian
    Okay, I thought my head hurt with regular regex, but I can't seem to find what I'm looking for with regexp in mysql. I'm trying to look for situations in news articles where a Textile-formatted url has not ended with a slash so: "Catherine Zeta-Jones":/cr/catherinezeta-jones/ visited stack overflow is ok but "Catherine Zeta-Jones":/cr/catherinezeta-jones visited stack overflow is not. [just used Catherine as an example because I'm assuming an alpha search wouldn't catch the hyphen] One of these days I'll have to do that goat sacrifice so I can gain the proper knowledge of regex. Thanks everyone!

  • Injecting tenant repositories with StructureMap in a multi-tenant MVC applicaiton

    - by FreshCode
    I'm implementing StructureMap in a multi-tenant ASP.NET MVC application to inject instances of my tenant repositories that retrieve data based on an ITenantContext interface. The Tenant in question is determined from RouteData in a base controller's OnActionExecuting. How do I tell StructureMap to construct TenantContext(tenantID); where tenantID is derived from my RouteData or some base controller property? Base Controller Given the following route: {tenant}/{controller}/{action}/{id} My base controller retrieves and stores the correct Tenant based on the {tenant} URL parameter. Using Tenant, a repository with an ITenantContext can be constructed to retrieve only data that is relevant to that tenant. Based on the other DI questions, could AbstractFactory be a solution?
