  • java.lang.ClassCastException: $Proxy99 cannot be cast

    - by svaret
    Hi, I am using JBoss4.2.2 and java6. The deployed ear's name is apa.ear In a servlet I have the following code line: placeBid = (PlaceBid) context.lookup("apa/" + PlaceBid.class.getSimpleName() + "/remote"); I have a generated jboss-app.xml like this: <jboss-app> <loader-repository>apa:app=ejb3</loader-repository> </jboss-app> When trying to get the PlaceBid via the context I get this exception java.lang.ClassCastException: $Proxy99 cannot be cast to se.nextit.actionbazaar.buslogic.PlaceBid The PlaceBid interface looks like this: @Remote public interface PlaceBid { Long addBid(String userId, Long itemId, Double bidPrice); } When I run the example coming with EJB3 in action it works. EJB3 in action sample code comes with ant building. I want to use Maven so I have rearranged the code some. However, I don't understan what I am doing wrong here. I have some thoughts about the jboss-app.xml file. I am not sure of how its content should look like. Grateful for any help. Best wishes Lasse

  • Unobtrusive jQuery and Rails with AJAX and form validation

    - by bogumbiker
    Hello, I am looking for a way to call successfully custom function from submitHandler to do proper ajax post. Here is my custom function: jQuery.fn.submitWithAjax = function() { this.submit(function() { $.post(this.action, $(this).serialize(), null, "script"); return false; }) return this; }; Before using validate plugin I had following which worked fine: $(document).ready(function() { $("#my_form").submitWithAjax(); } Now I have added the validation part and have no idea how to call my custom submitWithAjax function?? $(document).ready(function() { $("#my_form").validate({ /*Validations - works perfectly!! */ }, submitHandler: function(form) { /* $("#my_form").submitWithAjax(); - this works but introduces recursion */ /* how to call custom subitWithAjax() ????? */ } }); }) Thanks!

  • How can I marshall between XLOPER and VARIANT?

    - by Tim
    I'm working on an Excel plugin (XLL), which communicates with COM objects. So, I have to marshall between XLOPER and VARIANT. I've got most of this working, but arrays are definitely a pain. I need to support 1- and 2D arrays. I imagine someone has already had to deal with this before. Is there some library available to simplify this? Are there good tools for dealing with VARIANT, SAFEARRAY, and XLOPER (and XLOPER12)?

  • Netbeans Profile JUnit 4 problem

    - by Krishna K
    I have a unit test that takes 200 sec to run. I am trying to use NetBeans profiler to speed it up. But the profiler doesn't run the unit test. It just creates an object of the test and exits. Doesn't run the actual test methods or @Before / @After methods. This is a maven project with surefire and junit 4. And partial output is below.

  • JSP Googlemaps taglib not found, where have I gone wrong?

    - by James.Elsey
    I'm trying to add Google Maps onto my JSPs by using the Googlemaps taglib. I've added this into my maven pom <dependency> <groupId>com.lamatek</groupId> <artifactId>googlemaps</artifactId> <version>0.98c</version> <scope>provided<>/scope </dependency> This then included the googlemaps-0.98c library under my project libraries in NetBeans, I right clicked and selected Manually install artifact and located the googlemaps.jar file I had downloaded. I've then added this into my taglibs file <%@taglib prefix="googlemaps" uri="/WEB-INF/googlemaps" %> And have then included this where I actually want to show a map on my jsp <googlemaps:map id="map" width="250" height="300" version="2" type="STREET" zoom="12"> <googlemaps:key domain="localhost" key="xxxx"/> <googlemaps:point id="point1" address="74 Connors Lane" city="Elkton" state="MD" zipcode="21921" country="US"/> <googlemaps:marker id="marker1" point="point1"/> </googlemaps:map> But when I load up my application, I get the following error. org.apache.jasper.JasperException: /jsp/dashboard.jsp(1,1) /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found root cause org.apache.jasper.JasperException: /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found Have I missed something simple? I'm unable to spot what I've done wrong so far..

  • will_paginate undefined method error - Ruby on Rails

    - by bgadoci
    I just installed the gem for will_paginate and it says that it was installed successfully. I followed all the instructions listed with the plugin and I am getting an 'undefined method `paginate' for' error. Can't find much in the way of Google search and haven't been able to fix it myself (obviously). Here is the code: PostsController def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts = Post.paginate :page => params[:page], :per_page => 50 respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end /model/post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy cattr_reader :per_page @@per_page = 10 end /posts/views/index.html.erb <%= will_paginate @posts %>

  • Binding elements when modal window loads from AJAX (jQuery)

    - by thinkswan
    I'd like to set up a drag'n'drop list inside a modal window. The window's content is loaded via an AJAX call, so I believe I need to use jQuery's .live() method. Here is my current code: $('#cboxLoadedContent').live('load', function() { // Event for sortable page lists $('ul#pageList').sortable(); }); How can I set up bindings when the modal window loads? The modal window comes from the colorbox plugin. Note: I'm guessing that 'load' is not the right event to use, because if I throw a simple alert() in there, it doesn't even show up when the window loads.

  • Silverlight 4 crashing every browser (SL3 doesn't)

    - by Simon_Weaver
    I am testing my application on a number of machines. It is fine on every machine except 1. I'm having problems with one XP machine where in internet explorer, chrome and firefox the Silverlight plugin crashes on EVERY page with Silverlight. Pages that used to work fine with silverlight 3 crash instantly - including my app and the Silverlight Beta 4 demo page!!! The browser crashes instantly and doesn't even attempt to load the page. I don't know how to debug this because there's no error. It just crashes instantly in all these browsers. Reinistalling, rebooting didn't fix the problem.

  • Aptana/Eclipse "Mark for Publishing feature"

    - by Mickey Cheong
    Hi, I was wondering whether Aptana or Eclipse has a plugin/feature that allows you to "Mark for Publishing" once you save the file. So, as you working on different files, you can just save it and it will be mark for publishing. Once you are done with the files, you can just click "Publish All" and it will upload to the FTP server that setup with the Project. I learnt about this great feature in Coda (Mac). I was wondering if there is one in Eclipse/Aptana. Else, if there any alternative. Cheers, Mickey

  • jQuery/AJAX type-ahead/auto-complete

    - by Prasad
    I have read several articles/questions/forums discussing the best auto-complete plugin for jQuery. After trying several good ones, I've realized a flaw in most. If you are looking up countries and type 'In', a couple of countries show up. If you continue typing I-n-d-i-a, this results in 5 AJAX calls (see http://www.freeimagehosting.net/uploads/6f1bcd69e1.png) its quite natural that India is a subset of In, so why call again? We need to simply filter the retrieved list client-side. Anyone knows about such an implementation? What is the status of the Jquery Autocomplete feature? I read at StackOverflow that it is no longer available with Jquery; but the Jquery website has a 'New' mark besides the link to Autocomplete. Thanks

  • Sending Facebook notifications

    - by antpaw
    Hey i have a little facebook iframe application written with rails and the facebooker plugin. I can loop through the users friends and see whether they also have this application. To do this I use a fql qeury, and my own html (no fbml). Now i want to create a button right beside every friend who doesn't have this app, that sends an invite massage. Is it possible to do this without this FBML/JS voodoo? I looked through the RESTful api but the only thing i could found was this deprecated method :( Can someone provide me an code example on how to do this? I really don't want to use this FBML stuff because it doesn't fit into the ui concept of the app, but if that the only way, please explain how to do this (every fbml tag I've tried is just invisible :( ) Thanks a lot.

  • Should I use WPF or ASP.NET for my next Web Application development?

    - by gap
    We have a web application that has been built using MySQL / PHP / Javascript+JQuery, with server-side HTML generation. The problem is that of the 10 software developers that work for the company, none are PHP experts (we're all .NET / C# developers). I need to make a recommendation to my management team on which technologies to use as the platform for the next generation of web application products. I want to leverage the .NET / C# expertise which the company has and is otherwise building, and so am inclined to recommend some Microsoft technologies. We don't want a client-side plugin, and we don't need flashy animations/multimedia, so I'm ruling out Silverlight. Is WPF ready for primetime? Is ASP.NET deprecated by WPF? How do I choose between these two technologies? Big Question, I know... I can refine it based on your comments if necessary. Thanks for taking the time.

  • How can I prevent Rails from "pluralizing" a column name?

    - by Mike
    I'm using dwilkie's foreigner plugin for rails. I have a table creation statement that looks like: create_table "agents_games", :force => true, :id => false do |t| t.references :agents, :column => :agent_id, :foreign_key => true, :null => false t.references :games, :column => :game_id, :foreign_key => true, :null => false end However, this generates the following SQL: [4;35;1mSQL (2.7ms)[0m [0mCREATE TABLE "agents_games" ("agents_id" integer NOT NULL, "games_id" integer NOT NULL) [0m I want the columns to be called agent_id and game_id - not agents_id and agent_id. How can I prevent Rails from pluralizing the columns? I tried the following in my enviornment.rb file, which didn't help: ActiveSupport::Inflector.inflections do |inflect| inflect.uncountable "agent_id", "game_id" end

  • jQuery UI sortable issue with helper offset value being same as scroll offset on FireFox only

    - by James
    I have a problem with a jQuery UI 1.7.2 sortable list in Firefox, IE7-8 work fine. When I'm scrolled down a bit, the helper element seems to have an offset of the same height that I'm scrolled down which makes it impossible to see which item you originally started dragging. How do I fix this or work around the issue? If there is no fix what is a really good alternative drag-able plugin? Here are my initialization parameters for the sortable. $("#sortable").sortable( {placeholder: 'ui-state-highlight' } ); $("#sortable").disableSelection();

  • InvalidCastException when creating an instance using assembly.CreateInstance

    - by Yossi Dahan
    I'm looking for an explanation for the following - I have an assembly I'm loading using Assembly assembly = Assembly.LoadFrom(filename); I then loop on all the types in the assembly, and wish to try and find out if a type implements a particular interface and if so I want an instance of that type, I've tried several things which did not work, but when I fell back to the most basic (and probably inefficient) way, I realised there's something more fundamental I don't understand - foreach (Type t in assembly.GetTypes()) { foreach (Type i in t.GetInterfaces()) { if (i.FullName == pluginInterfaceType.FullName) { object o = assembly.CreateInstance(t.ToString()); IInterface plugin = (IInterface)o; That last line causes an InvalidCastException, despite the fact that the type created definitely implements that interface. Further more - if I use Activator.CreateInstance instead of Assembly.CreateInstance (which I don't want to do), casting to the interface works just fine.

  • Stack Overflow-like tag selector for Rails

    - by David Tildon
    I want to use tags for a model in my Rails application, and I'd like to have the same kind of tag selection mechanism that Stack Overflow has when asking a question. I.e. I type in 'rails' and it drops down a list of tags that include 'rails', and I can go on to add more tags from there. Is there a plugin that can do this? I'm comfortable putting together the tag model and migrations myself, that isn't an issue. I just need something to handle the AJAX and javascript. I'm using prototype and Rails 2.3.

  • How to hook Pivotal Tracker to Redmine?

    - by cloneofsnake
    Our company is currently using Redmine, it's great for general tasks / troubleshooting (operation) but for development, I would like to adopt a more agile tool... and I found it in pivotaltracker. I googled but couldn't find any info., so that gave me a good excuse to try StackOverflow. Has anyone done it? I'm thinking of using PivotalTracker as the main tool, and all activities will be posted back to redmine for archiving and reporting. (Redmine isn't particularly strong at that either, but it does have a budget plugin and I can query the database directly for my custom reports.) Thanks.

  • Git diff gone mad?

    - by dr Hannibal Lecter
    I'm trying to figure out what's going on with my local Git repo. I edit a file. Git reports everything has changed in the file (I only changed one line) At first I think "must be a newline problem", but it's not. I do a diff in TortoiseGit, everything looks fine. I do a diff with Netbeans (git plugin), everything seems fine. I do a reset, backup the file, modify it, git again reports everything has changed. I do a binary compare in Total Commander, the files have no differences except for the single line I changed. I do a hard reset again. Git tells me it was done successfully. Git status still says my file has changed. I diff the thing and there are no differences - bug git says there are. I've tried using both git bash and gui, with same results (I'm on Windows). Any clues, what's going on here?

  • JQuery treeview - add node(s) in middle of tree

    - by Chris
    Hi all, I'm just getting started with JQuery and the treeview plugin so this should be a relatively easy question: The example code for adding branches to the tree: var newnodes = $("<li><span class='folder'>New Sublist</span><ul>" + "<li><span class='file'>Item1</span></li>" + "<li><span class='file'>Item2</span></li></ul></li>").appendTo("#browser"); $("#browser").treeview({ add: branches }); Works fine for me, but adds the new branch at the end of the tree - instead what I want is to be able to select a specific node and add to that branch. I've managed to get the node being added by using the id of the particular node instead of the whole treeview in - appendTo("nodeID") However I can't get the tree to render correctly, either with: $("nodeID").treeview({ add: branches }); or $("browser").treeview({ add: branches }); or calling it on both without arguments. Cheers in advance

  • List of objects to JSON to Html Table?

    - by DaveDev
    If I have a list of objects IEnumerable<MyType> myTypes; Is it possible for me to return this to the client as JSON return Json(myTypes); and if so, is it possible for me to convert this (now JSON format) list to a when it gets to the client? Is there any jQuery plugin to do this? The thing is, there's loads of other stuff I need to send as JSON also, so generating a table with a PartialView and embedding that into the JSON is a extra complexity that I'd like to avoid. Thanks.

  • How to express inter project dependencies in Eclipse PDE

    - by Roland Tepp
    I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)
