  • RequestDispatcher forward between Tomcat instances

    - by MontyBongo
    I have a scenario where I have single entry point Servlet and further Servlets that requests are forwarded to that undertake heavy processing. I am looking at options to distribute this load and I would like to know if it is possible using Tomcat or another platform to forward requests between Servlets sitting on different servers using a cluster type configuration or similar. I have found some documentation on clustering Servlets and Tomcat but none indicate if Servlet request forwarding is possible from what I can see. http://java.sun.com/blueprints/guidelines/designing_enterprise_applications_2e/web-tier/web-tier5.html http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html

  • How to unit test a Spring MVC controller using @PathVariable?

    - by Martiner
    I have a simple annotated controller similar to this one: @Controller public class MyController { @RequestMapping("/{id}.html") public String doSomething(@PathVariable String id, Model model) { // do something return "view"; } } and I want to test it with an unit test like this: public class MyControllerTest { @Test public void test() { MockHttpServletRequest request = new MockHttpServletRequest(); request.setRequestURI("/test.html"); new AnnotationMethodHandlerAdapter() .handle(request, new MockHttpServletResponse(), new MyController()); // assert something } } The problem is that AnnotationMethodHandlerAdapter.handler() method throws an exception: java.lang.IllegalStateException: Could not find @PathVariable [id] in @RequestMapping at org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter$ServletHandlerMethodInvoker.resolvePathVariable(AnnotationMethodHandlerAdapter.java:642) at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.resolvePathVariable(HandlerMethodInvoker.java:514) at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.resolveHandlerArguments(HandlerMethodInvoker.java:262) at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.invokeHandlerMethod(HandlerMethodInvoker.java:146)

  • Linux Kernel Module - Creating proc file - proc_root undeclared error

    - by Zach
    I copy and paste code from this URL for creating and reading/writing a proc file using a kernel module and get the error that proc_root is undeclared. This same example is on a few sites so I assume it works. Any ideas why I'd get this error? Does my makefile need something different. Below is my makefile as well: Example code for a basic proc file creation (direct copy and paste to get initial test done): http://tldp.org/LDP/lkmpg/2.6/html/lkmpg.html#AEN769 Makefile I'm using: obj-m := counter.o KDIR := /MY/LINUX/SRC PWD := $(shell pwd) default: $(MAKE) ARCH=um -C $(KDIR) SUBDIRS=$(PWD) modules

  • What is the simplest way to implement multithredding in c# to existing code

    - by Kaeso
    I have already implemented a functionnal application that parses 26 pages of html all at once to produce an xml file with data contained on the web pages. I would need to implement a thread so that this method can work in the background without causing my app to seems unresponsive. Secondly, I have another function that is decoupled from the first one which compares two xml files to produce a third one and then transform this third xml file to produce an html page using XSLT. This would have to be on a thread, where I can click Cancel to stop the thread whithout crashing the app. What is the easiest best way to do this using WPF forms in VS 2010 ? Note: I cannot use the BackgroundWorker component as it is grayed out in the toolbox.

  • Asp.Net MVC Create/Update/Delete with composite key

    - by nubm
    Hi, I'm not sure how to use composite key. My Categories table has CategoryId (PK,FK), LanguageId (PK,FK), CategoryName CategoryId | LanguageId | CategoryName 1 | 1 | Car 1 | 2 | Auto 1 | 3 | Automobile etc. I'm following this design The default action looks like // // GET: /Category/Edit/5 public ActionResult Edit(int id) { return View(); } and ActionLink <%= Html.ActionLink("Edit", "Edit", new { id= item.CategoryId }) %> Should I use something like <%= Html.ActionLink("Edit", "Edit", new { id= (item.CategoryId + "-" + item.LanguageId) }) %> so the url is /Category/Edit/5-5 and // // GET: /Category/Edit/5-5 public ActionResult Edit(string id) { // parse id return View(); } or change the route to something like /Category/Edit/5/5 Or there is some better way?

  • setting jQuery .data() within .getJSON callback

    - by hackmaster.a
    I'm doing a couple of .getJSON calls and if any one of them succeeds, I'm trying to set a bool to true so I can then do some other stuff elsewhere on the page. I was trying to use jquery's .data() function, but I don't seem able to set it from inside the .getJSON callback. for example: $('#citations_button').data('citations', false); $.getJSON(apaurl, function(data) { $('#apacite').html("<td class=\"bibInfoLabel\">APA Citation</td><td class=\"bibInfoData\">"+data+"</td>"); $('#citations_button').data('citations', true); }, "html"); // other .getJSONs look like above... console.log("citations? "+$('#citations_button').data('citations')); prints false, even when I know the data came through. I thought this would work since .data() uses the cache to store the key/value pair. how can i flag successes?? appreciate any assistance!!

  • Get the currently saved object in a view in Django

    - by mridang
    Hi, I has a Django view which is accessed through an AJAX call. It's a pretty simple one — all it does is simply pass the request to a form object and save the data. Here's a snippet from my view: form = AddSiteForm(request.user, request.POST) if form.is_valid(): obj = form.save(commit=False) obj.user = request.user obj.save() data['status'] = 'success' data['html'] = render_to_string('site.html', locals(), context_instance=RequestContext(request)) return HttpResponse(simplejson.dumps(data), mimetype='application/json') How do I get the currently saved object (including the internally generated id column) and pass it to the template? Any help guys? Mridang

  • How to login to wordpress programmatically?

    - by T-Rex
    I need to perform some action in wordpress admin panel programmatically but can't manage how to login to Wordpress using C# and HttpWebRequest. Here is what I do: private void button1_Click(object sender, EventArgs e) { string url = "http://localhost/wordpress/wp-login.php"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); CookieContainer cookies = new CookieContainer(); SetupRequest(url, request, cookies); //request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; //request.Headers["Accept-Language"] = "uk,ru;q=0.8,en-us;q=0.5,en;q=0.3"; //request.Headers["Accept-Encoding"] = "gzip,deflate"; //request.Headers["Accept-Charset"] = "windows-1251,utf-8;q=0.7,*;q=0.7"; string user = "test"; string pwd = "test"; request.Credentials = new NetworkCredential(user, pwd); string data = string.Format( "log={0}&pwd={1}&wp-submit={2}&testcookie=1&redirect_to={3}", user, pwd, System.Web.HttpUtility.UrlEncode("Log In"), System.Web.HttpUtility.UrlEncode("http://localhost/wordpress/wp-admin/")); SetRequestData(request, data); ShowResponse(request); } private static void SetupRequest(string url, HttpWebRequest request, CookieContainer cookies) { request.CookieContainer = cookies; request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; uk; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)"; request.KeepAlive = true; request.Timeout = 120000; request.Method = "POST"; request.Referer = url; request.ContentType = "application/x-www-form-urlencoded"; } private void ShowResponse(HttpWebRequest request) { HttpWebResponse response = (HttpWebResponse)request.GetResponse(); responseTextBox.Text = (((HttpWebResponse)response).StatusDescription); responseTextBox.Text += "\r\n"; StreamReader reader = new StreamReader(response.GetResponseStream()); responseTextBox.Text += reader.ReadToEnd(); } private static void SetRequestData(HttpWebRequest request, string data) { byte[] streamData = Encoding.ASCII.GetBytes(data); request.ContentLength = streamData.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(streamData, 0, streamData.Length); dataStream.Close(); } But unfortunately in responce I get only HTML source code of login page and it seems that cookies don't contain session ID. All requests which I perform after that code also return HTML source of login page so I can assume that it does not login correctly. Can anybody help me to solve that problem or give working example? Main thing which I want to achieve is scanning for new images in Nextgen Gallery plugin for Wordpress. Is there XML-RPC way of doing that? Thanks in advance.

  • AjaxSubmit File Upload - Trying to get response $(document).ready() to fire

    - by ncyankee
    I'm using the jquery form plugin (http://malsup.com/jquery/form/) to upload a file via ajax which is processed in the background. The upload is working correctly, and I am using ASP.Net MVC to return a partial view which contains a $(document).ready call to setup a 'timer' to check on the status of the upload file's processing status. When I return the partial view which contains a script block wit ha $(document).ready call, it is never fired, therefore the 'timer' to check for the status of the upload is never started. When I do this via a regular $.post call (without upload) the function fires correctly after the html is loaded into the DOM. Is there anything else I need to do when calling the ajaxSubmit function to get this to fire? Just a sample bit of code: $('form').live('submit', function () { $(this).ajaxSubmit({ success: function (data) { $('#statusDiv').html(data); } }); return false; });

  • Erb with Sinatra in ruby

    - by JP
    So I have a webserver I've built using sinatra, the meat of which goes like this: set :variable,"value" get '/' do erb :index end And, of course, the template in views/index.erb which looks something like this: <html> <!-- etc --> <ul> <% my_array.each do |thing| %> <%="Something: #{thing}, variable from sinatra: #{settings.variable}"%> <% end %> </ul> </html> If you try running code like this you'll notice that you can't access sinatra's settings variable from inside erb templates. Any ideas how I can achieve this while keeping its simplicity? Thanks in advance!

  • Integrating CKeditor to my symfony2 project

    - by Jishnu G Nair
    I was trying to integrate ckeditor to my symfony2 project so that some of the textarea will have the ckeditor html editor. I brought the ckeditor on my required textarea by calling the class="ckeditor" in my form. The issue that I am facing now is that when I use the ckeditor the submit button of my form will not work instead I will have to use the built in "Save" option of the ckeditor toolbar for submitting the form. When I remove the ckeditor from the textareas and use normal textarea the submit button seems to work. I do not want to use the "Save" button on the ckeditor toolbar to submit my form. Is there a workaround to make the submit button work? Tried googling out for possible solutions but could not find any. P.S: I would also like to know if there are other html text editors like ckeditor that would work well with symfony2 and link to implementation instructions.

  • Shopping Portal based on XML Data - XSLT or PHP?

    - by buggy1985
    For my bachelor thesis I want to implement a shopping (price comparison) portal prototype based on XML Data. The main requirement is to get a very clear and customizable HTML template, which should be hosted by the customer on his own webserver. I'm not very sure if XSLT meets this requirements, as it generates a lot of xsl-related code. It is not easy to understand for people with little HTML skills. I have some experience with the PHP templating engine Smarty. The syntax is much better, but I'm not sure if it's a good idea to parse the XML data with PHP, as it is very complex. Which language should I choose for a web application with high complexity? XSLT or PHP?

  • javascript onkeypressed not giving current text box content

    I have an html form like this: <form id="boxy" action="layout.html" method="get" accept-charset="utf-8"> <input type="text" id="a" onkeypress="Boxy.Check(this);"> </form> Invoking javascript like this: Boxy.Check = function() { input = document.getElementById(this.currentSelector.id).value; console.log("\"" + input + "\""); }; However, this.value is the previous value before onkeypress. For example, if I just type "A" into the form, console.log() prints "". And if I type "AA", console.log prints "A". Is there a way to get the current content of the input?

  • Drupal node_save and special characters.

    - by Pierre
    Hello, i'm trying to create nodes and taxonomy terms through a custom php script by using the node_save() function. I'm working on drupal 6. It's working well (thanks to previous questions on stackoverflow) except for accented letters. Indeed, when a title or a taxonomy term contain "é", "è" or "à", the sentence is cut before those special characters. For example, a title like that: "Bonjour les éléphants" will create a node with "Bonjour les " as title. I don't know if it's linked to my database or if i have to use a special encoding in php (iconv() blabla) The fact is, for drupal titles, i can not use html encoding (for example: é is é in html) because drupal will render &eacute and not é... When i create a taxonomy or a title manually, i have no problems and the accented letter is saved in the database as "é". Soo if you can help me to create terms and title with accented letters, that will be great : ) Thank you !

  • curl object moved here error, bash

    - by adam n
    I'm trying to download an html file with curl in bash. When I download it manually, it works fine. However, when i try and run my script through crontab, the output html file is very small and just says "Object moved to here." with a broken link. Does this have something to do with the sparse environment the crontab commands run it? I found this question: http://stackoverflow.com/questions/1279340/php-ssl-curl-object-moved-error but i'm using bash, not php. What are the equivalent command line options or variables to set to fix this problem in bash? (I want to do this with curl, not wget)
