  • Avoiding try/catch hell in my web pages

    - by Shaun_web
    I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

  • j_security_check to SSO in different module under Oracle App Server?

    - by thebearinboulder
    I have an existing j2ee application running on Oracle App Server. It is targeted towards paying customers so the content is secured and a SSO module properly intercepts all requests for secured content. Now the company is adding a unbranded public-facing module with a number of unsecured pages. At one point the user is expected to register for a free account and log in to proceed further. Think doctors adding a public-facing site with information for potential patients, or lawyers adding a public-facing site with information for potential clients. There's some information on the session and the usual approach would be to authenticate the user, persist the session information using the now-known user id, invalidate the existing session (to prevent certain types of attacks), the reload the session information before returning to the user. I can't just persist it under the session id since that's about to change. The glitch is that the existing application already has an SSO module and I get a 404 error every time I try to direct to j_security_check. I've tried that, /sso/j_security_check, even http://localhost/sso/j_security_check, all without success. I noticed that an earlier question said that tomcat requires access to a secured page before j_security_check is even visible. I don't know if that's the case with Oracle AS. Ideas? Or is the best approach to continue arguing that we have a different user base so it would be better to handle authentication in our own module anyway?

  • Java REST implementation: Jersey vs CXF

    - by dexter
    What do you think is the advantages/disadvantages between this two libraries? Which of these two are best suited for production environment? By the way I will be using JSON instead of XML. I also would like to know what library is most supported by the community e.g. tutorials, documentation.

  • Spring 3.0 REST implementation or Jersey?

    - by hnilsen
    Hi, SO! I'm currently trying to figure out which implementation of JSR-311 I'm going to recommend further up the food chain. I've pretty much narrowed it down to two options - Spring 3.0 with it's native support for REST - or use Sun's own Jersey (Restlets might also be an option). To me it doesn't seem to be much of a difference in the actual syntax, but there might be issues with performance that I haven't figured out yet. The service is meant to replace some heavy-duty EJB's and make a RESTful Webservice instead. The load is expected to be rather high, up in the 100k users per day (max) range, but will be seriously load balanced. Thanks for all your insights.

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

    How is it possible to allow a user to create a webpage containing some html, based on their entries in a form? ie. I would want them to be able to input a name and when the button is clicked, a webpage called that name would be created. I imagine that this must be possible in php, but what functions/code would I be using? Thank you!

  • Visual Studio Deployment Package - change the file structure the .zip creates?

    - by KevinUK
    Everything works as expected but I would like to improve the directory structure that the .zip produces. When I create a deployment package I have it create in a custom directory which works fine but the .zip it creates is in the structure of: content/c_c/users/pcName/documents/VS2010/Projects/ProjectName/obj/release/package/packageTmp Only in the packageTmp directory do I get to the files I want! Is there a way for the created zip to not include all of those empty directories?

  • how works applications which blocks web sites?

    - by noisy
    I know only one low-level way of blocking websites - hosts file. However, it is obvious that main stream programs has some other way of achieving this. I have an idea for new model of this kind of program, but without possibility of blocking sites it is useless :(

  • CSS: How the backgrounds can extend the border and overlap?

    - by AlexStack
    I'm designing a navigation bar as shown in image below (a) with the following code: <ul> <li class="unselected">Step 1</li> <li class="selected">Step 2</li> <li class="unselected">Step 3</li> <li class="unselected">Step 4</li> <li class="unselected">Step 5</li> </ul> I want to have one background image for unselected steps (d) and one for the selected step (c). For simplicity let's assume Step 1 and Step 5 use the same background as well. I want to adjust the button background in HTML only with a class name. The question is how can I achieve the result with CSS? I just want to know how background of two neighbor elements can overlap each other?

  • How to transfer visitors to the servers closes to them and where to place the servers?

    - by user2971623
    I am focusing on providing fast page refreshes for my visitors and I wonder where is the smartest spot to place my servers on? I understand that the best would be to place a server in every country or even city, but that is of course not doable with my economy. I am thinking of maybe setting up three servers, one in the middle of USA (Kansas?), one in Italy and one in Sweden. What do you think about that? I don't care about Africa since they haven't even got computers so I won't get traffic from there anyway. China, North Korea etc are probably just visiting chinese websites, they barely know english anway... The next problem is how do I redirect a visitor from Finland to the Swedish server? I don't want the visitor from Finland to be using the USA server or vice versa.

  • Virtual PC (XPMode) - How to access Webserver on guest from host

    - by sannoble
    I have Windows XP running inside Windows 7 via Virtual PC (XPMode) and installed Zend Server CE on the virtual XP guest. The webserver is running and can be accessed on the guest, but I cannot access the webserver from the Win7 host. I configured a static IP address and subnet of 255.255.255.0 on the guest and can ping this IP from the guest but not from the host. The other way it works fine, i.e. I can ping the host from the guest. I can also access the internet from the virtual XP guest. I tried different Network Options in the VirtualPC settings, but nothing helps. Googling the topic I couldn't find anything helpful yet. Any idea, what I could try to access the webserver on the virtual XP guest from the Win7 host?

  • Why is good UI design so hard for some Developers?

    - by Chris Ballance
    Some of us just have a hard time with the softer aspects of UI design (myself especially). Are "back-end coders" doomed to only design business logic and data layers? Is there something we can do to retrain our brain to be more effective at designing pleasing and useful presentation layers? Colleagues have recommended a few books me including The Design of Sites, Don't make me think and Why Software sucks , but I am wondering what others have done to remove their deficiencies in this area?

  • prevent IE Mobile from scaling web pages automatically

    - by Adam
    I have not been able to get IE mobile to stop automatically resizing my site design. I am using three stylesheets with media queries to display the site differently on different device screens. I've included the meta tag so it shows the mobile stylesheet on IE mobile but it keeps setting the viewport at 320X480 instead of using the actual size of 480X800. How can I force it to display at the actual screen size instead of scaling for a smaller resolution?

  • $_FILES is null, $_POST is not null

    - by Cory Dee
    When I am going to upload a file, my $_POST variable knows the file name, but the $_FILES variable is null. I've used this code before, so I'm really stumped. Here's what I'm using for input: <label for="importFile">Attach Resume:</label> <input type="hidden" name="MAX_FILE_SIZE" value="10000000"> <input type="file" name="importFile" id="importFile" class="validate['required']"> And for processing: $uploaddir = "E:/Sites/OPL/2008/assets/apps/newjobs/resumes/"; $uploadfile = $uploaddir . time() . '-' . urlencode(basename($_FILES['importFile']['name'])); if (!move_uploaded_file($_FILES['importFile']['tmp_name'], $uploadfile)) { echo 'Error uploading file. Error number: ' . $_FILES['importFile']['error']; var_dump($_FILES['importFile']); echo $_POST['importFile']; die(); } Which is giving me this result: Error uploading file. Error number: NULL Maintaining The OPL Website.doc Any help would be greatly appreciated.

  • What to do with lookup entities selected from drop down select ? How to send them to the service lay

    - by arrages
    I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

  • IE sends multiple cookies with same name?

    - by akach
    I have a strange bug that occurs in IE7/XP and IE8/Vista on my website. IE sends two cookies named PHPSESSID. How to reproduce: Clear cookies in IE (not necessary if you never visited unisender.com). Visit unisender.com (exactly without www to reproduce!) and it will redirect to www.unisender.com Login with any valid username and password (I've registered username testmsdn with password testmsdn - feel free to use for testing) Run your favourite capture-the-traffic program (I prefer wireshark) Now click any menu link (e.g. "messages") Look at captured traffic - you will see that IE sends double PHPSESSID cookie (and you are logged out after click because of this). It seems like first PHPSESSID is from unisender.com and second from www.unisender.com. Captured sample: GET /en/letter_list HTTP/1.1 Accept: image/gif, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/x-shockwave-flash, / Referer: http://www.unisender.com/en/intro Accept-Language: ru User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.5.21022; .NET CLR 3.5.30729; FDM; .NET CLR 3.0.30729) Accept-Encoding: gzip, deflate Host: www.unisender.com Connection: Keep-Alive Cookie: authchallenge=3a9cfcfc9fe33822e3e21d75c8a3d3e4; PHPSESSID=14ea1cb133632951592397c86eaf037e; us_reg_ref=unknown; us_reg_url=http%3A%2F%2Funisender.com%2F; __utma=1.778517853.1271204400.1271204400.1271204400.1; __utmb=1.3.10.1271204400; __utmc=1; __utmz=1.1271204400.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); PHPSESSID=65e110aeb995a66b9dc8da5656c7a3da; last_login_name=testmsdn I've tried to use session and non-session cookies, tried to use .unisender.com instead of unisender.com for cookie - nothing helps. I suppose there should not be cookies with same name. Am I right? Is it a bug in IE? If it's a bug then is there a workaround? Or am I wrong and it's an expected behavior?

  • Retrieve web user's Identity outside of request scope

    - by Kendrick
    I have an ASP.NET app that logs Audit reports using nHibernate's IPreUpdateListener. In order to set the current user in the Listener events, I was using System.Security.Principal.WindowsIdentity.GetCurrent(). This works fine when debugging on my machine, but when I move it to the staging server, I'm getting the ASP.NET process credentials, not the requesting user. In the ASP.NET page, I can use Request.LogonUserIdentity (which works fine since I'm using integrated authentication), but how do I reference this user directly without having to pass it directly to my event? I don't want to have to pass this info through the pipeline because it really doesn't belong in the intermediate events/calls.

  • Windows Service Start-Up Error 1069

    - by Gavin
    Hello, I am installing a new windows service coded in C# on a server. I installed the service fine on the server, but once i manually start up the service on a server, with the same login credentials that our other services use, i get the fatal error message notification: "Could not start the %service name% on Local Computer. Error 1069: The Service did not start due to a logon failure." I looked in the event log and i got a 7038 and 7000 event id error in that order. 7038 event id message: "The %service name% service was unable to log on as %login% with the currently configured password due to the following error: Logon failure: unknown user name or bad password. To ensure that the service is configured properly, use the Services snap-in in Microsoft Management Console (MMC)." 7000 event id message: "The %service name% service failed to start due to the following error: The service did not start due to a logon failure. " I have other services that are using the same exact login account and they work fine. Is there something simple I could be missing? Thanks
