  • Design for tagging system in GAE-J

    - by tempy
    I need a simple tagging system in GAE-J. As I see it, the entity that is being tagged should have a collection of keys referring to the tags with which it's associated. A tag entity should simply contain the tag string itself, and a collection of keys pointing to the entities associated with the tag. When an entity's list of tags is altered, the system will create a new tag if the tag is unknown, and then append the entity's key to that tag's key collection. If the tag already exists, then the entity's key is simply appended to the tag's key collection. This seems relatively straight-forward and uncontroversial to me, but I would like some feedback on this design, just to be sure.

  • Does anyone know how to make a custom search in Bugzilla?

    - by Mugen
    I'm trying to make a search in Bugzilla which is used during our evaluation. The search basically lists how many defects were logged by each employee. Does anyone know how we can do this in Bugzilla? (The advanced search page has options for "Advanced Searching Using Boolean Charts: ". I think it could probably be using that? )

  • Link to another file in chrome extension

    - by Hintswen
    I want to have a link in the popup.html file for my extension that loads another file (which will be included with the extension) how can I do this? or will I need to keep it in the same page? I tried using this code: <a href="/mail.html"> <img id="newmail_icon" src="" width="16" height="16" /> <span id="newmail">loading</span><br /> </a> But when I click the link nothing happens. I just found out that adding target="_blank" to the link will make it work and open in a new tab, but I can't get it to open in the popup. I have tried target="_self" but it didn't do anything.

  • How to call a javascript function from one frame to another in Chrome/Webkit

    - by bambax
    I have developped an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in FF but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in FF 3.6 and Chrome 3 but in Chrome 5 it throws the above error...

  • Refactored App Engine project - now Eclipse is infinitely building the project without end

    - by Yog
    I renamed some files in my App Engine project and refactored code, changing references to variables. Everything seemed fine until I changed the references in the web.xml for the project. Then I got a complaint about some error with the DataNucleus enhancer and now the project build process is stuck at 22%. I tried stopping Eclipse and restarting but the build process keeps hanging. Any tips on how to clean out whatever it's getting stuck on?

  • is jQuery 1.4.2 compatible with Closure Compiler?

    - by Mohammad
    According to the official release statement version 1.4 has been re-written to be compressed with Closure Compiler yet when I use the online version of closure compiler I get 130 warnings. This is the code I use. // ==ClosureCompiler== // @compilation_level ADVANCED_OPTIMIZATIONS // @output_file_name default.js // @code_url http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js // ==/ClosureCompiler== And as far as I know you get the real benefit of Closure Compiler if you include the library with your code also, so it removes the unused functions. Yet my testing show that I can't get any further than compressing the library itself.. What am I doing wrong? Any kind of insight will be much appreciated.

  • How to set Chrome's user script version number.

    - by Atli
    Hey. I've been wondering how I might set the version number displayed for user-scripts in Chrome's extension tab So far the obvious methods have failed: // ==UserScript== // @version 1.1.5 // @uso:version 1.1.5 // ==/UserScript== I know Greasemonkey for Firefox doesn't use a version value, but since Chrome actually displays a version number, I thought it might. Perhaps this is a feature that has not been implemented? Or maybe it was never intended to be there, but it is there because extensions have version numbers, and user-scripts are currently installed as extensions? (I'm using the Linux beta, version: 4.0.249.43, by the way) Thanks. Edit: Seems this is listed as an unconfirmed bug in the Chromium bug database (Issue 30760)

  • Give me a practical use-case of Multi-set

    - by Calm Storm
    I would like to know a few practical use-cases (if they are not related/tied to any programming language it will be better).I can associate Sets, Lists and Maps to practical use cases. For example if you wanted a glossary of a book where terms that you want are listed alphabetically and a location/page number is the value, you would use the collection TreeMap(OrderedMap which is a Map) Somehow, I can't associate MultiSets with any "practical" usecase. Does someone know of any uses? http://en.wikipedia.org/wiki/Multiset does not tell me enough :) PS: If you guys think this should be community-wiki'ed it is okay. The only reason I did not do it was "There is a clear objective way to answer this question".

  • RoR - Polyline in GoogleMaps

    - by Arwed
    I'm using Ym4r and want to add a polyline to my map. This works: polyline = GPolyline.new([[27.4037755983,89.4263076782],[27.5155793659,89.3245124817]],"#ff0000",3,1.0) @map.record_init @map.add_overlay(polyline) But this doesn't: polystring = "[27.4037755983,89.4263076782],[27.5155793659,89.3245124817]" polyline = GPolyline.new([polystring],"#ff0000",3,1.0) @map.record_init @map.add_overlay(polyline) Any idea why? Regards Arwed

  • GAE and Socket Data

    - by Vinod
    I have a field device which keeps on sending data over to any designated port using sockets. I am planning to use GAE for server-side infrastructure. I read GAE does not support sockets. But i can configure the device to send the data over port 80. so we wrote a genericservlet to capture this data on GAE. But it is not obtaining any values from the client. any suggestions to fix this issue?

  • JTA or LOCAL transactions in JPA2+Hibernate 3.6.0?

    - by Pangea
    We are in the process of re-thinking our tech stack and below are our choices (We can't live without Spring and Hibernate due to the complexity etc of the app). We are also moving from J2EE 1.4 to JEE 5. Tech stack JEE 5 JPA 2.0 (I know JEE 5 only supports JPA 1.0 but we want to use Hibernate as the JPA provider) Hibernate 3.6.0 (We already have lots of hbm files with custom types etc. so we doesn't want to migrate them at this time to JPA. This means we want both jpa/hbm mappings work together and hence the Hibernate as the JPA provider instead of using the default that comes with App Server) Now the problems is that I want to stick with local transactions but other team members want to use JTA. I have been working with J2EE for last 9 years and I've heard time and again people suggesting to stick with local transactions if I doesn't need two phase commits. This is not only for performance reasons but debugging/troubleshooting a local transaction is lot easier than a distributed transaction. My suggestion is to use spring declarative transaction management + local transactions (HibernateTransactionManager) I want to make sure if I am being paranoid or I have a valid point. I'd like to hear what the rest of the JEE world thinks. Thank you.

  • Problem with GwtUpload on GAE

    - by weesilmania
    I'm using GwtUpload to upload images on GAE. The problem is that the images seem to get much bigger when I move them into a blob. I've noticed the same for simple text fields and in that case I've realised that some weirdo characters are being appended to the end of the field values (encoding right?). Can anyone help? public class ImageUploadServlet extends AppEngineUploadAction { /** * Maintain a list with received files and their content types */ Hashtable<String, File> receivedFiles = new Hashtable<String, File>(); Hashtable<String, String> receivedContentTypes = new Hashtable<String, String>(); private Objectify objfy; public ImageUploadServlet() { ObjectifyService.register(Thumbnail.class); objfy = ObjectifyService.begin(); System.out.println("ImageUploadServlet init"); } /** * Override executeAction to save the received files in a custom place and * delete this items from session. */ @Override public String executeAction(HttpServletRequest request, List<FileItem> sessionFiles) throws UploadActionException { Thumbnail t = new Thumbnail(); for (FileItem item : sessionFiles) { //CacheableFileItem item = (CacheableFileItem)fItem; if (false == item.isFormField()) { System.out.println("the name 1st:" + item.getFieldName()); try { // You can also specify the temporary folder InputStream imgStream = item.getInputStream(); Blob imageBlob = new Blob(IOUtils.toByteArray(imgStream)); t.setMainImage(imageBlob); System.out.println("blob: " + t.getMainImage()); } catch (Exception e) { throw new UploadActionException(e.getMessage()); } } else { System.out.println("the name 2nd:" + item.getFieldName()); String name = item.getFieldName(); String value; try { InputStream is = item.getInputStream(); StringWriter writer = new StringWriter(); IOUtils.copy(is, writer,"UTF-8"); value = writer.toString(); writer.close(); System.out.println("parm name: " + name); System.out.println("parm value: " + value + " **" + value.length()); System.out.println(item.getContentType()); if (name.equals("thumb-name")) { t.setName(value); } } catch (IOException e) { // TODO Auto-generated catch block System.out.println("Error"); e.printStackTrace(); } } removeSessionFileItems(request); } objfy.put(t); return null; } As an example the size of the image is 20kb, and the lib has some debugging that confirms that this is the case when it's uploading the file but the blob ends up being over 1 MB.

  • Error handling in the RequestHandler without embedding in URI

    - by hyn
    When a user sends a filled form, I want to print an error message in case there is an input error. One of the GAE sample codes does this by embedding the error message in the URI. Inside the form handler (get): self.redirect('/compose?error_message=%s' % message) and in the handler (get) of redirected URI, gets the message from request: values = { 'error_message': self.request.get('error_message'), ... Is there a way to accomplish the same without embedding the message in the URI?

  • Chrome extension sendRequest from async callback not working?

    - by Eugene
    Can't figure out what's wrong. onRequest not triggered on call from async callback method, the same request from content script works. The sample code below. background.js ============= ... makeAsyncRequest(); ... chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { switch (request.id) { case "from_content_script": // This works console.log("from_content_script"); sendResponse({}); // clean up break; case "from_async": // Not working! console.log("from_async"); sendResponse({}); // clean up break; } }); methods.js ========== makeAsyncRequest = function() { ... var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function() { if (xhr.readyState == 4) { ... // It works console.log("makeAsyncRequest callback"); chrome.extension.sendRequest({id: "from_async"}, function(response) { }); } } ... }; UPDATE: manifest configuration file. Don't no what's wrong here. { "name": "TestExt", "version": "0.0.1", "icons": { "48": "img/icon-48-green.gif" }, "description": "write it later", "background_page": "background.html", "options_page": "options.html", "browser_action": { "default_title": "TestExt", "default_icon": "img/icon-48-green.gif" }, "permissions": [ "tabs", "http://*/*", "https://*/*", "file://*/*", "webNavigation" ] }

  • Chrome not sending POST requests on localhost, Firefox works fine

    - by AP257
    I have copied the simple Django forms example exactly, running on localhost. The basic contact form example should submit a POST request when you click the Submit button. I'm running Chrome on Mac Snow Leopard, and whenever I submit the form, the page simply reloads with an empty form: I can see from the runserver output that it's not sending a POST - instead it's sending a GET request. If I open the same page in Firefox on Mac Snow Leopard, and submit the form, I can see it's sending a POST request (as it should be). Looking at the source in Chrome, the form definitely says method="post". <form action="/contact/" method="post"> <p><label for="id_subject">Subject:</label> <input id="id_subject" type="text" name="subject" maxlength="100" /></p> <p><label for="id_message">Message:</label> <input type="text" name="message" id="id_message" /></p> <p><label for="id_sender">Sender:</label> <input type="text" name="sender" id="id_sender" /></p> <p><label for="id_cc_myself">Cc myself:</label> <input type="checkbox" name="cc_myself" id="id_cc_myself" /></p> <input type="submit" value="Submit" /> </form> External sites with POST forms seem to work OK in Chrome. In addition, if I fill the form in incorrectly, in Chrome the page just reloads, with a GET request, as before; in Firefox the form gets validated, as it should. I've tried with other POST forms on localhost and got the same result. I know Chrome for Mac has its quirks, but what on earth is going on?
