  • Decode amf3 object using PHP

    - by Xuki
    My flash code: var request=new URLRequest('http://localhost/test.php'); request.method = URLRequestMethod.POST; var data = new URLVariables(); var bytes:ByteArray = new ByteArray(); bytes.objectEncoding = ObjectEncoding.AMF3; //write an object into the bytearray bytes.writeObject( { myString:"Hello World"} ); data.data = bytes; request.data = data; var urlLoader:URLLoader = new URLLoader(); urlLoader.dataFormat = URLLoaderDataFormat.BINARY; urlLoader.addEventListener(Event.COMPLETE, onCompleteHandler); urlLoader.load(request); function onCompleteHandler(evt:Event):void { trace(evt.target.data); } PHP code: define("AMF_AMF3",1); $data = $_POST['data']; echo amf_decode($data, AMF_AMF3); Basically I need to send an AMF3 object from Flash to PHP and unserialize it. I'm using AMFEXT extension but couldn't get it to work. Any idea?

  • JQuery Deferred - Adding to the Deferred contract

    - by MgSam
    I'm trying to add another asynchronous call to the contract of an existing Deferred before its state is set to success. Rather than try and explain this in English, see the following pseudo-code: $.when( $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 1 done.') jqXhr.pipe( $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 2 done.'); }, }) ); }, }), $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 3 done.'); }, }) ).then(function(){ console.log('All done!'); }); Basically, Call 2 is dependent on the results of Call 1. I want Call 1 and Call 3 to be executed in parallel. Once all 3 calls are complete, I want the All Done code to execute. My understanding is that Deferred.pipe() is supposed to chain another asynchronous call to the given deferred, but in practice, I always get Call 2 completing after All Done. Does anyone know how to get jQuery's Deferred to do what I want? Hopefully the solution doesn't involve ripping the code apart into chunks any further. Thanks for any help.

  • ASP.NET MVC: How to validate an Ajax form with a specified UpdateTargetID?

    - by Bryan Roth
    I'm trying to figure out how to show validation errors after a user submits an Ajax form that has its UpdateTargetID property set. I'm stumped on how to update the Ajax form with the validation errors without returning the Create PartialView into the results div. If the form is valid, then it should return the Records PartialView. Create.ascx <% Using Ajax.BeginForm("Create", "Record", New Record With {.UserID = Model.UserID}, New AjaxOptions With { .UpdateTargetId = "results", .LoadingElementId = "loader" })%> Date Located <%= Html.TextBoxFor(Function(model) model.DateLocated)%> <%= Html.ValidationMessageFor(Function(model) model.DateLocated) %> Description <%= Html.TextBoxFor(Function(model) model.Description)%> <%= Html.ValidationMessageFor(Function(model) model.Description) %> <input id="btnSave" type="submit" value="Create" /> <span id="loader" class="loader">Saving...</span> <%End Using%> Records.ascx <div id="results"> ... </div> RecordController.vb Function Create(ByVal newRecord As Record) As ActionResult ValidateRecord(newRecord) If Not ModelState.IsValid Then Return PartialView("Create", newRecord) End If _repository.Add(newRecord) _repository.Save() Dim user = _repository.GetUser(newRecord.UserID) Return PartialView("Records", user) End Function

  • AS3 Memory Conservation (Loaders/BitmapDatas/Bitmaps/Sprites)

    - by rinogo
    I'm working on reducing the memory requirements of my AS3 app. I understand that once there are no remaining references to an object, it is flagged as being a candidate for garbage collection. Is it even worth it to try to remove references to Loaders that are no longer actively in use? My first thought is that it is not worth it. Here's why: My Sprites need perpetual references to the Bitmaps they display (since the Sprites are always visible in my app). So, the Bitmaps cannot be garbage collected. The Bitmaps rely upon BitmapData objects for their data, so we can't get rid of them. (Up until this point it's all pretty straightforward). Here's where I'm unsure of what's going on: Does a BitmapData have a reference to the data loaded by the Loader? In other words, is BitmapData essentially just a wrapper that has a reference to loader.content, or is the data copied from loader.content to BitmapData? If a reference is maintained, then I don't get anything by garbage collecting my loaders... Thoughts?

Why is this the case?

  • strategy for choosing proper object and proper method

    - by zerkms
    in the code below at first if statements block (there will be more than just "worker" condition, joined with else if) i select proper filter_object. After this in the same conditional block i select what filter should be applied by filter object. This code is silly. public class Filter { public static List<data.Issue> fetch(string type, string filter) { Filter_Base filter_object = new Filter_Base(filter); if (type == "worker") { filter_object = new Filter_Worker(filter); } else if (type == "dispatcher") { filter_object = new Filter_Dispatcher(filter); } List<data.Issue> result = new List<data.Issue>(); if (filter == "new") { result = filter_object.new_issues(); } else if (filter == "ended") { result = filter_object.ended_issues(); } return result; } } public class Filter_Base { protected string _filter; public Filter_Base(string filter) { _filter = filter; } public virtual List<data.Issue> new_issues() { return new List<data.Issue>(); } public virtual List<data.Issue> ended_issues() { return new List<data.Issue>(); } } public class Filter_Worker : Filter_Base { public Filter_Worker(string filter) : base(filter) { } public override List<data.Issue> new_issues() { return (from i in data.db.GetInstance().Issues where (new int[] { 4, 5 }).Contains(i.RequestStatusId) select i).Take(10).ToList(); } } public class Filter_Dispatcher : Filter_Base { public Filter_Dispatcher(string filter) : base(filter) { } } it will be used in some kind of: Filter.fetch("worker", "new"); this code means, that for user that belongs to role "worker" only "new" issues will be fetched (this is some kind of small and simple CRM). Or another: Filter.fetch("dispatcher", "ended"); // here we get finished issues for dispatcher role Any proposals on how to improve it?

  • Authenticated WCF: Getting the Current Security Context

    - by bradhe
    I have the following scenario: I have various user's data stored in my database. This data was entered via a web app. We'd like to expose this data back to the user over a web service so that they can integrate their data with their applications. We would also like to expose some business logic over these services. As such we do not want to use OData. This is a multi-tenant application so I only want to expose their data back to them and not other users. Likewise, the business logic we expose should be relative to the authenticated user. I would like let the user use an OASIS scheme to authenticate with the web service -- WCF already allows for this out of the box as far as I understand -- or perhaps we can issue them certificates to authenticate with. That bit hasn't really been worked out yet. Here is a bit of pseudo-code of how I envision this would work within the service: function GetUsersData(id) var user := Lookup User based on Username from Auth Context var data := Get Data From Repository based on "user" return data end function For the business logic scenario I think it would look something like this: function PerformBusinessLogic(someData) var user := Lookup User based on Username from Auth Context var returnValue := Perform some logic based on supplied data return returnValue end function The hard bit here is getting the current username (or cert info in the cert scenario) that the user authenticated with! Does WCF even enable this scenario? If not would WSE3 enable this? Thanks,

  • Is NSPasteboard thread-safe?

    - by Joe
    Is it safe to write data to an NSPasteboard object from a background thread? I can't seem to find a definitive answer anywhere. I think the assumption is that the data will be written to the pasteboard before the drag begins. Background: I have an application that is fetching data from Evernote. When the application first loads, it gets the meta data for each note, but not the note content. The note stubs are then listed in an outline view. When the user starts to drag a note, the notes are passed to the background thread that handles getting the note content from Evernote. Having the main thread block until the data is gotten results in a significant delay and a poor user experience, so I have the [outlineView:writeItems:toPasteboard:] function return YES while the background thread processes the data and invokes the main thread to write the data to the pasteboard object. If the note content gets transferred before the user drops the note somewhere, everything works perfectly. If the user drops the note somewhere before the data has been processed... well, everything blocks forever. Is it safe to just have the background thread write the data to the pasteboard?

  • What is the best software design to use in this scenario

    - by domdefelice
    I need to generate HTML snippets using jQuery. The creation of those snippets depends on some data. The data is stored server-side, in session (where PHP is used). At the moment I achieved this - retrieving the data from the server via AJAX in form of JSON - and building the snippets via specific javascript functions that read those data The problem is that the complexity of the data is getting bigger and hence the serialization into JSON is getting even more difficult since I can't do it automatically. I can't do it automatically because some information are sensible so I generate a "stripped" version to send to the client. I know it is difficult to understand without any code to read, but I am hoping this is a common scenario and would be glad for any tip, suggestion or even design-pattern you can give me. Should I store both a complete and a stripped data on the server and then use some library to automatically generate the JSON from the stripped data? But this also means I have to get the two data synchronized. Or maybe I could move the logic server-side, this way avoiding sending the data. But this means sending javascript code (since I rely on jQuery). Maybe not a good idea. Feel free to ask me more details if this is not clear. Thank you for any help

  • How to output JSON from within Django and call it with jQuery from a cross domain?

    - by Emre Sevinç
    For a bookmarklet project I'm trying to get JSON data using jQuery from my server (which is naturally on a different domain) running a Django powered system. According to jQuery docs: "As of jQuery 1.2, you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". jQuery automatically replaces the ? with the correct method name to call, calling your specified callback." And for example I can test it successfully in my Firebug console using the following snippet: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any& format=json&jsoncallback=?", function(data){ alert(data.title); }); It prints the returned data in an alert window, e.g. 'Recent uploads tagged cat'. However when I try the similar code with my server I don't get anything at all: $.getJSON("http://mydjango.yafz.org/randomTest?jsoncallback=?", function(data){ alert(data.title); }); There are no alert windows and the Firebug status bar says "Transferring data from mydjango.yafz.org..." and keeps on waiting. On the server side I have this: def randomTest(request): somelist = ['title', 'This is a constant result'] encoded = json.dumps(somelist) response = HttpResponse(encoded, mimetype = "application/json") return response I also tried this without any success: def randomTest(request): if request.is_ajax() == True: req = {} req ['title'] = 'This is a constant result.' response = json.dumps(req) return HttpResponse(response, mimetype = "application/json") So to cut a long story short: what is the suggested method of returning a piece of data from within a Django view and retrieve it using jQuery in a cross domain fashion? What are my mistakes above?

  • Hybrid EAV/CR model via WCF (and statically-typed language)?

    - by Pat
    Background I'm working on the architecture for a cloud-based LOB application, using Silverlight for the client, WCF, ASP.NET/C# for server and SQL Server for storage. The data model requires some flexibility per user (ability to add custom properties and define validation rules for them, for example), and a hybrid EAV/CR persistence model on the server side will suit nicely. Problem I need an efficient and maintainable technology and approach to handle the transformation from the persisted EAV model to/from WCF (and similarly allow the client to bind to the resulting data - DataGrid is a key UI element)? Admission: I don't yet know enough about WCF to understand if it supports ExpandoObject directly, but I suspect it will. Options I started off looking at WCF RIA services, but quickly discovered they're heavily dependent upon both static type data and compile-time code generation. Neither of these appeal. The options I'm considering include: Using WCF RIA services and pass the data over the network directly in EAV form (i.e. Dictionary), and handle the binding issue purely on the client side (like this) Using a dynamic language (probably IronPython) to handle both ends of the communication, with plumbing to generate the necessary CLR type data on the client to allow binding, and transform to/from EAV form on the server (spam preventer stopped me from posting a URL here, I'll try it in a comment). Dynamic LINQ (CreateClass() and friends), although I'm way out of my depth there and don't know what the limitations on that approach might be yet. I'm interested in comments on these approaches as well as alternative approaches that might solve the problem. Other Notes The Silverlight client will not be the only consumer of the service, making me slightly uncomfortable with option #1 above. While the data model is flexible, it's not expected to be modified heavily. For argument's sake, we could assume that we might have 25 distinct data models active at a given time, with something like 10-20 unique data fields/rules each. Modifications to the data model will happen infrequently (typically when a new user is initially configured).

  • Trouble adding video controls to video selected by XML comboBox

    - by user560128
    Hello, it's been a few years since I've touched flash, so perhaps I'm just overlooking something. If anyone could look at the code and offer any suggestions that would be awesome. What's working, I select a video from a combobox that is populated from an XML file, pick the video and it plays. I've been trying to add pause/play, stop, forward and reverse functionality, once I get that to work I also want to add a video scrubber(slider), and previous/next buttons to go to the previous/next video as listed in the xml file. At the moment I have a component button on the stage called playButton, which I'm trying to use for pause/play functionality. Below is my code, the player control is at the very bottom. Thanks. import fl.data.DataProvider; var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); var videosXML:XML = new XML(); var loader:URLLoader = new URLLoader(); var request:URLRequest= new URLRequest("xml/videos.xml"); var videos:Array = new Array({label:"Select a Video",data:""}); var client:Object = new Object(); theVideo.attachNetStream(ns); ns.client = client; loader.addEventListener(Event.COMPLETE,loaderOnComplete); loader.load (request); function loaderOnComplete(event:Event):void{ videosXML = new XML(event.target.data); for each (var video:XML in videosXML.video){ videos.push({label:video.name.toString(),data:video.url.toString()}); } moviesCB.dataProvider = new DataProvider(videos); } moviesCB.addEventListener(Event.CHANGE, changeHandler); function changeHandler(event:Event):void { if(ComboBox(event.target).selectedItem.data != ""){ ns.play(ComboBox(event.target).selectedItem.data); } }; client.onMetaData = metadataHandler; function metadataHandler(md:Object):void{ } //player controls playButton.onRelease = function() { ns.pause(); }

  • Flash/Flex sending XML to Rails App

    - by bdicasa
    I'm trying to send some XML to a rails app in Flex. I'm using the URLRequest and URLLoader objects. However, I'm having trouble determining how to send the XML and _method parameter to the rails app using these flash objects. Below is how I'm currently trying to achieve this. var request:URLRequest = new URLRequest(); request.method = URLRequestMethod.POST; request.data = new Object(); request.data.xml = Blog.xml.toXMLString(); request.contentType = "text/xml"; var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, saveCompleteHandler); var saveUrl:String = ""; saveUrl = BASE_URL; if (Blog.isNewBlog) { // Set the rails REST method. request.data._method = "POST"; saveUrl += "blogs.xml"; } else { // Set the rails REST method. request.data._method = "PUT"; saveUrl += "blogs/" + Blog.id.toString() + ".xml"; } request.url = saveUrl; //trace(request.data.toString()); loader.load(request); However the only data that is getting sent to the server is [Object object]. If some one could let me know where I'm going wrong I'd greatly appreciate it. Thanks.

  • Error: "Cannot simultaneously fetch multiple bags" when calling Configuration.BuildSessionFactory();

  • Using Doctrine to abstract CRUD operations

    - by TomWilsonFL
    This has bothered me for quite a while, but now it is necessity that I find the answer. We are working on quite a large project using CodeIgniter plus Doctrine. Our application has a front end and also an admin area for the company to check/change/delete data. When we designed the front end, we simply consumed most of the Doctrine code right in the controller: //In semi-pseudocode function register() { $data = get_post_data(); if (count($data) && isValid($data)) { $U = new User(); $U->fromArray($data); $U->save(); $C = new Customer(); $C->fromArray($data); $C->user_id = $U->id; $C->save(); redirect_to_next_step(); } } Obviously when we went to do the admin views code duplication began and considering we were in a "get it DONE" mode so it now stinks with code bloat. I have moved a lot of functionality (business logic) into the model using model methods, but the basic CRUD does not fit there. I was going to attempt to place the CRUD into static methods, i.e. Customer::save($array) [would perform both insert and update depending on if prikey is present in array], Customer::delete($id), Customer::getObj($id = false) [if false, get all data]. This is going to become painful though for 32 model objects (and growing). Also, at times models need to interact (as the interaction above between user data and customer data), which can't be done in a static method without breaking encapsulation. I envision adding another layer to this (exposing web services), so knowing there are going to be 3 "controllers" at some point I need to encapsulate this CRUD somewhere (obviously), but are static methods the way to go, or is there another road? Your input is much appreciated.

  • Can I delay the keyup event for jquery?

    - by Paul
    I'm using the rottentomatoes movie API in conjunction with twitter's typeahead plugin using bootstrap 2.0. I've been able to integerate the API but the issue I'm having is that after every keyup event the API gets called. This is all fine and dandy but I would rather make the call after a small pause allowing the user to type in several characters first. Here is my current code that calls the API after a keyup event: var autocomplete = $('#searchinput').typeahead() .on('keyup', function(ev){ ev.stopPropagation(); ev.preventDefault(); //filter out up/down, tab, enter, and escape keys if( $.inArray(ev.keyCode,[40,38,9,13,27]) === -1 ){ var self = $(this); //set typeahead source to empty self.data('typeahead').source = []; //active used so we aren't triggering duplicate keyup events if( !self.data('active') && self.val().length > 0){ self.data('active', true); //Do data request. Insert your own API logic here. $.getJSON("http://api.rottentomatoes.com/api/public/v1.0/movies.json?callback=?&apikey=MY_API_KEY&page_limit=5",{ q: encodeURI($(this).val()) }, function(data) { //set this to true when your callback executes self.data('active',true); //Filter out your own parameters. Populate them into an array, since this is what typeahead's source requires var arr = [], i=0; var movies = data.movies; $.each(movies, function(index, movie) { arr[i] = movie.title i++; }); //set your results into the typehead's source self.data('typeahead').source = arr; //trigger keyup on the typeahead to make it search self.trigger('keyup'); //All done, set to false to prepare for the next remote query. self.data('active', false); }); } } }); Is it possible to set a small delay and avoid calling the API after every keyup?

The basic architecture is this: Ping an external API to get back a JSON object Work client-side with that object, and eventually have a "download me" link This link sends the data to my server, which processes it and sends it back with a mime type application/json, which (should) prompt the user to download the file locally. Right now here are my pieces: Server Side Code <?php $data = array('zero', 'one', 'two', 'testing the encoding'); $json = json_encode($data); //$json = json_encode($_GET['']); //eventually I'll encode their data, but I'm testing header("Content-type: application/json"); header('Content-Disposition: attachment; filename="backup.json"'); echo $_GET['callback'] . ' (' . $json . ');'; ?> Relevant Client Side Code $("#download").click(function(){ var json = JSON.stringify(collection); //serializes their object $.ajax({ type: "GET", url: "http://www.myURL.com/api.php?callback=?", //this is the above script dataType: "jsonp", contentType: 'jsonp', data: json, success: function(data){ console.log( "Data Received: " + data[3] ); } }); return false; }); Right now when I visit the api.php site with Firefox, it prompts a download of download.json and that results in this text file, as expected: (["zero","one","two","testing the encoding"]); And when I click #download to run the AJAX call, it logs in Firebug Data Received: testing the encoding which is almost what I'd expect. I'm receiving the JSON string and serializing it, which is great. I'm missing two things: The Actual Questions What do I need to do to get the same prompt-to-download behavior that I get when I visit the page in a browser (much simpler) How do I access, server-side, the json object being sent to the server to serialize it? I don't know what index it is in the GET array (silly, I know, but I've tried almost everything)

  • Zend framework controller action helper

    - by guptanikhilchandra
    I am getting fatal error after adding the action helper class. I am trying to load layout corresponding to called layout. Following is my code snippet: First of all i added a helper class under application/controller/helpers: class Zend_Controller_Action_Helper_Layout extends Zend_Controller_Action_Helper_Abstract { public $pluginLoader; public function __construct() { // TODO Auto-generated Constructor $this->pluginLoader = new Zend_Loader_PluginLoader (); } public function preDispatch() { $bootstrap = $this->getActionController()->getInvokeArg('bootstrap'); $config = $bootstrap->getOptions(); $module = $this->getRequest()->getModuleName(); if (isset($config[$module]['resources']['layout']['layout'])) { $layoutScript = $config[$module]['resources']['layout']['layout']; $this->getActionController()->getHelper('layout')->setLayout($layoutScript); } } } Then i added a loader in bootstrap.php: protected function _initLayoutHelper() { $this->bootstrap('frontController'); Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH .'/controllers/helpers'); $layout = Zend_Controller_Action_HelperBroker::addHelper(new Zend_Controller_Action_Helper_Layout()); } Following is my application.ini: [production] autoloaderNamespaces.tree = "Tree_" phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers" resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" resources.frontController.helperDirectory = APPLICATION_PATH "/controllers/helpers" resources.modules[] = "" contact.resources.frontController.defaultControllerName = "index" resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.layout.layout = layout admin.resources.layout.layout = admin admin.resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.view[] = [staging : production] [testing : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 [development : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 While running this code i am getting following errors: Warning: include(Zend\Controller\Action\Helper\LayoutLoader.php) [function.include]: failed to open stream: No such file or directory in D:\personal\proj\renovate\library\Zend\Loader.php on line 83 Warning: include() [function.include]: Failed opening 'Zend\Controller\Action\Helper\LayoutLoader.php' for inclusion (include_path='D:\personal\proj\renovate\application/../library;D:\personal\proj\renovate\library;.;C:\php5\pear') in D:\personal\proj\renovate\library\Zend\Loader.php on line 83 Fatal error: Class 'Zend_Controller_Action_Helper_LayoutLoader' not found in D:\personal\proj\renovate\application\Bootstrap.php on line 33 Kindly let me know, how can i come out from this issue.

  • CGLIB proxy error after spring bean definition loading into XmlWebApplicationContext at runtime

    - by VasylV
    I load additional singleton beans definitions at runtime from external jar file into existing XmlWebApplicationContext of my application: BeanFactory beanFactory = xmlWebApplicationContext.getBeanFactory(); DefaultListableBeanFactory defaultFactory = (DefaultListableBeanFactory)beanFactory; final URL url = new URL("external.jar"); final URL[] urls = {url}; ClassLoader loader = new URLClassLoader(urls, this.getClass().getClassLoader()); defaultFactory.setBeanClassLoader(loader); final ClassPathBeanDefinitionScanner scanner = new ClassPathBeanDefinitionScanner(defaultFactory); final DefaultResourceLoader resourceLoader = new DefaultResourceLoader(); resourceLoader.setClassLoader(loader); scanner.setResourceLoader(resourceLoader); scanner.scan("com.*"); Object bean = xmlWebApplicationContext.getBean("externalBean"); After all above xmlWebApplicationContext contains all external definitions of beans. But when i am trying to get bean from context exception is thrown: Couldn't generate CGLIB proxy for class ... I saw in debug mode that in the bean initialization process first time proxy is generated by org.springframework.aop.aspectj.autoproxy.AspectJAwareAdvisorAutoProxyCreator and than it is tried to generate proxy with org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator but fails with mentioned exception.

  • JTable Insert row and refresh

    - by user269723
    Hi All, I am trying to create simple application where JTable gets updated and refreshed after data is changed.Structure is as follows. 1)Class Main which contains JFrame,JTable details. 2)SampleTableModel class which extends AbstractTableModel.I am overriding most of the methods.`import javax.swing.table.; import javax.swing.event.; import java.util.*; public class SampleTableModel extends AbstractTableModel { public SampleTableModel(){ // this.addTableModelListener( } String[] columnNames = {"A","B","C","D","E"}; int[][] data = {{1,2,3,4,5},{5,6,7,8,9},{12,13,14,15,16}}; Vector dataVector = new Vector(); public Object getValueAt(int rowIndex,int columnIndex) { return data[rowIndex][columnIndex]; } public int getColumnCount(){ return 5; } public int getRowCount(){ return 3; } public String getColumnName(int columnIndex){ return columnNames[columnIndex]; } public void setValueAt(Object value,int row,int column){ data[row][column] =99; } public void notifyTable(AEMessage message){ /* * This method will be called from another class to update JTable. * */ data[0][1]=999; data[0][2]=8838; data[1][1]=8883; fireTableRowsUpdated(0,3); } } ` As you can see, notifyTable will be called from another class(which is actually a thread-which calls this method frequently) Problem is I don't see data being changed in JTable.I see only the initialized data. In the Main class- I am setting like this- RVJDataTable.setModel(new SampleTableModel());
