  • tomcat multithreading problem

    - by jutky
    Hi all I'm writing a java application that runs in Tomcat, on a multi-core hardware. The application executes an algorithm and returns the answer to the user. The problem is that even when I run two requests simultaneously, the tomcat process uses at most one CPU core. As far as I understand each request in Tomcat is executed in separate thread, and JVM should run each thread on separate CPU core. What could be the problem that bounds the JVM or Tomcat to use no more than one core? Thanks in advance.

  • Possible to map a new file extension to an existing handler in ASP.NET?

    - by Dave
    I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension. I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension. First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests? Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way? Thanks, Dave

  • Redirecting the response from a filter throws an IllegalStateException

    - by Ritesh M Nayak
    I am writing a filter that will handle all authentication related tasks. My filter is a standard servlet filter as shown below @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { UserSession attribute = (UserSession)request.getSession().getAttribute("user_session_key"); if(attribute!=null && attribute.isValid()) { //proceed as usual, chain.doFilter(req, res); return; } else { //means the user is not authenticated, so we must redirect him/her to the login page ((HttpServletResponse)res).sendRedirect("loginpage"); return; } } But when I do this, I get an IllegalStateException thrown by Tomcat's ResponseFacade. How do I acheive this in a filter. I read in other SO threads that in TOmcat this is a problem as the response object is already commited. How do I get past this ?

  • Bypass using Alter Access Mappings for to Open Web from SPItemEventProperties

    - by Greg Ogle
    In the following code, // class overrides SPItemEventreceiver public override void ItemAdding(SPItemEventProperties properties) { using (var site = new SPSite(properties.SiteId)) //SiteId is integer { ... } } The following exception is thrown: System.IO.FileNotFoundException: The Web application at http://URL could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application. One way to work around this is to hard-code (or configure) the URL specified in Alternate Access Mappings. Putting the correct URL in Alternate Access Mappings is ultimately the correct solution, but if possible, I need a work-around that doesn't require configuration.

  • Can you do a struts2 action redirect using POST instead of GET?

    - by Andy Pryor
    <action name="actionA" class="com.company.Someaction"> <result name="success" type="redirect-action"> <param name="actionName">OtherActionparam> <param name="paramA">${someParams}</param> <param name="paramB">${someParams}</param> <param name="aBoatLoadOfOtherParams">${aBoatLoadOfOtherParams}</param> </result> </action> In the above action map, I am redirecting from SomeAction to OtherAction. I am having issues, because unfortunately I need to pass a large amount of data between the two actions. IE7 will only allow GET requests to be like 2k, so its blowing up when I'm just over that limit when the response calls a get request to the other action. Is it possible for me to set this redirect, to end up with a POST being called to the other action?

  • How do I measure the time elapsed when calling a WCF Webservice?

    - by Manuel R.
    We want to track the time taken by a web service call between a client and the server. This time should not include the time taken by the server to process the request. The idea is that we want to see how much time of a web service call is lost due to the actual transfer trough the network. Does WCF already offer something in this direction? Of course I could just add a timer on the client and subtract the server processing time but that wouldn't be very elegant.

  • The whole site is blocked while one page is waiting for blocking operation (PHP, ASP.NET). Why?

    - by artvolk
    Good day! I've found interesting behaviour for both LAMP stack and ASP.NET. The scenario: There is page performing task in 2-3 minutes (making HttpWebRequest for ASP.NET and curl for PHP). While this page is processed all other requests to this virtual host from the same browser are not processed (even if I use different browsers from one machine). I use two pages written in PHP and C#. I've tested with Apache+PHP in both mod_php and fast_cgi modes on Windows and Debian. For ASP.NET I use IIS6 (with dedicated app pool for this site and with default app pool) and IIS7 in integrated mode. I know that it is better to use async calls for such things, but I'm just curious why single page blocks the entire site and not only the thread processing the request? Thanks in advance!

  • Consuming WCF from BizTalk 2006r1

    - by Rob Bowman
    Hi I need to create an Orchestration in BizTalk 2006r1 that will consume a WCF basicHTTP web service. Does anyone have a pointers on how to do this please? The WCF service has been created by another team but I am able to request that they create an additional endpoint with binding configuration set to make calling from BizTalk SOAP adapter possible. I just created a simple test basicHTTP service that runs fine when tested from a command line client. When I got to BizTalk add web reference I am able to browse to the service but then get a message "Failed to add web reference" and it bombs out! Any help gratefully received. Thanks Rob.

  • In Sinatra, best way to serve iPhone layout vs. normal layout?

    - by Doug
    I'm writing a Sinatra app which needs to render different layouts based on whether the user is using an iPhone or a regular browser. I can detect the browser type using Rack-Mobile-Detect but I'm not sure of the best way to tell Sinatra which layout to use. Also, I have a feeling that how I choose to do this may also break page caching. Is that true? Example code: require 'sinatra/base' require 'haml' require 'rack/mobile-detect' class Orca < Sinatra::Base use Rack::MobileDetect helpers do def choose_layout if request.env['X_MOBILE_DEVICE'] == :iPhone # use iPhone layout else # use normal layout end end end before do # should I use a before filter? choose_layout() end get '/' do haml :home # with proper layout end end #Class Orca

  • Passing URIs as URL arguments in Drupal

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • Ideas for building vulnerabilities into your site?

    - by Jaco Pretorius
    I'm trying to create a programming challenge that would require developers to hack into the MVC site I create. The idea is obviously to teach them about preventing these types of attacks. The current idea I have is to build multiple vulnerabilities into the site - but the second vulnerability would require the first to be completed, etc. So I was thinking the first could be a sql injection attack, the second would require a modified GET request, etc. Exploiting the final vulnerability would reveal a specific piece of information which is proof that you have completed the entire challenge. This will not be deployed on a public site - it's simply a learning tool for developers at my company. I'm not looking for MVC-specific vulnerabilities - I'm simply using MVC because it allows me to work with the 'raw' HTML. Any ideas on the different vulnerabilities I can use?

  • How to store the result of a JSP in a string?

    - by Spines
    I want to store the result of a JSP in a string. For example, I want to be able to call a function like: String result = ProcessJsp("/jspfile.jsp"); Also, this must be rather efficient. Making a url request to the jsp and then storing it would definitely be too slow. How could I do this? Here are my thoughts on how to do this, though I'm not sure if it would work, and I'm hoping there is something simpler: Do RequestDispatcher("/jspfile.jsp").include(hreq, hresp), but instead of putting the real HttpResponse object in there, you put your own where the getWriter() method returns something that writes to your String or a memory buffer, etc.

  • What type of websites does memcached speed up

    - by Saif Bechan
    I have read this article about 400% boost of your website. This is done by a combination of nginx and memcached. The how-to part of this website is quite good, but i mis the part where it says to what types of websites this applies. I know nginx is a http engine, I need no explanation for that. I thought memcached had something to do with caching database result. However i don't understand what this has to do with the http request, can someone please explain that to me. Another question I have is for what types of websites is this used. I have a website where the important part of the website consist of data that changes often. Often being minutes. Will this method still apply to me, or should I just stick with the basic boring setup of apache and nothing else.

  • Accepting bank account information in a form

    - by jeffthink
    What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

    we are building a NAT program,we change each packet that comes from our internal subnet, change it's source IP address by libnet functions.( catch the packet with libpcap, put it sniff structures and build the new packet with libnet) over TCP, the syn/ack packets are good after the change, and when a HTTP-GET request is coming, we can see by wireshark that there is an error on the checksum field.. all the other fields are exactly the same as the original packet. Is anyone knows what can cause this problem? the new checksum in other packets is calculated as it should be.. but in the HTTP packet it doesn't..

  • In App Purchase no valid Product IDs

    - by david
    I'm trying to get In App Purchase with my existing iPad App working. I'm stuck retrieving the Product Information from App Store: - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response The SKProductsResponse only contains invalid Product IDs. I tried every potential solution I found here or on the net: my App ID has In App enabled I generated a new provisioning profile and installed it on my device I restarted the device my App ID is the same as in my Info.plist (it's in the Store since weeks) I added In App Purchases for the App with "cleared for sale" checked I added Screenshots to my In App Purchases I tried different naming schemes for the Product ID I made triple checked that I pass the correct Product ID to the SKProductsRequest I'm passing a NSSet to the SKProductsRequest instead of a MutableSet I updated my App with the upcoming version containing in App purchase and submitted it for Review I approved one of my In App Purchases, just to see if that helps I waited more than 24 hours All of these actions brought me nothing but invalid Product IDs. I hope someone can point me into the right direction, because I'm running out of ideas.

  • How can I quickly set up a RESTful site using PHP without a Framework?

    - by Sanoj
    I would like to quickly set up a RESTful site using PHP without learning a PHP Framework. I would like to use a single .htaccess-file in Apache (no mod_rewrite) or a single rule using Nginx, so I easyli can change web server without changing my code. So I want to direct all requests to a single PHP-file, and that file takes care of the RESTful-handling and call the right PHP-file. In example: The user request http://mysite.com/test The server sends all requests to rest.php The rest.php call test.php (maybe with a querystring). If this can be done, is there a free PHP-script that works like my rest.php? or how can I do this PHP-script?

  • Postgres : Post statement (or insert) asynchronous, non-blocking processing.

    - by Hassan Syed
    I'm wondering if it is possible, that after a collection of rows is inserted, to initiate an operation that is executed asynchronously, is non-blocking, and doesn't need to inform the originator of the request - of the result. I am working with large amounts of events and I can guarantee that the post-insert logic will not fail -- I just want to have a single insert thread in my event-sources, and I want this thread to keep flying without blocking, and without being responsible for any post-delivery book-keeping. I can tell you that I would potentially have a 100 of these jobs executing concurrently and each job might operate on 5 tables with anywhere between 200-1000 inserts on each of these tables. A hint in the right direction should be enough.

  • Django paging object has issues with Postgresql QuerySets

    - by pivotal
    I have some django code that runs fine on a SQLite database or on a MySQL database, but it runs into problems with Postgres, and it's making me crazy that no one has has this issue before. I think it may also be related to the way querysets are evaluated by the pager. In a view I have: def index(request, page=1): latest_posts = Post.objects.all().order_by('-pub_date') paginator = Paginator(latest_posts, 5) try: posts = paginator.page(page) except (EmptyPage, InvalidPage): posts = paginator.page(paginator.num_pages) return render_to_response('blog/index.html', {'posts' : posts}) And inside the template: {% for post in posts.object_list %} {# some rendering jazz #} {% endfor %} This works fine with SQLite, but Postgres gives me: Caught TypeError while rendering: 'NoneType' object is not callable To further complicate things, when I switch the Queryset call to: latest_posts = Post.objects.all() Everything works great. I've tried re-reading the documentation, but found nothing, although I admit I'm a bit clouded by frustration at this point. What am I missing? Thanks in advance.

  • Replacing delimiter characters in file path

    - by salvationishere
    I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\...". So my question is how do I convert this file path into single "\"? To clarify more, this is my code in context. Currently it is entering the If Directory does not Exist section. protected void btnAppend_Click(object sender, EventArgs e) { string fullpath = Page.Request.PhysicalPath; fullpath.Replace('\\', '\'); if (!Directory.Exists(fullpath)) { string msg = "<h1>The upload path doesn't exist: {0}</h1>";

  • TcpListener Socket still active after program exits.

    - by lnical
    I'm trying to stop a TCP Listener as my program is exiting. I do not care about any data that is currently active on the socket or any of the active client sockets. The socket clean up code is essentially: try { myServer.Server.Shutdown(SocketShutdown.Both) } catch (Exception ex) { LogException(ex) } myServer.Server.Close(0) myServer.Stop() myServer is a TCPListener On some occasions, Shutdown will thrown an exception System.Net.Sockets.SocketException: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied at System.Net.Sockets.Socket.Shutdown(SocketShutdown how) When this happens, the socket is never released. Even after the application exits netstat shows the socket is still in the listening state. I have not been able to create definitive reproduction scenerio, it happens at seemingly random times. Client Sockets are cleaned up independently. Do you have any suggestions to help me make this socket die?
