Does anyone know of a good article or tutorial on the Internet demonstrating the use of GWT leveraging a (ASP.NET) web service cross domain? To my knowledge, interacting with either XML or JSON should be possible from GWT, but becomes a lot more difficult when the web service is on a different domain. I've tried finding an article that ...
Hi, I'm currently experimenting with GWT and Spring. More specifically I wanted to make the GreetingService sample to work with Spring on the server side. There are a couple of articles available for realizing this (I'm linking them here since some of you may be interested): http://ice09.wordpress.com/2009/05/25/google-app-engine-spri...
How can I centralize management of a "loading" icon for GWT async RPC calls? I'm looking for a way to have every async call automatically kick off a timer. When the timer fires, if the RPC has not yet completed, a "loading" icon should be displayed. When the RPC completes (either onSuccess() or onFailure()) the loading icon should be ...
I have some JavaScript files, a main HTML file, a main CSS file, and some CSS files that get imported into the main one. I understand that I can put static files in two places: a) the 'war' folder; or b) the 'public' folder. Where is the best place to put my static files? Are the two locations treated differently? Is there a 'best prac...
I have a Composite whose main widget has two children, thus: public MyComposite() { child1 = new FlowPanel(); child1.getElement().setId("child1"); child2 = new FlowPanel(); child2.getElement().setId("child2"); panel = new FlowPanel(); panel.add(child1); panel.add(child2); initWidget(panel); } Some time after construction of ...
I've drawn a blank. Does GWT have a widget that produces the HTML P tag? I want just the P tag to appear in the DOM, without any extraneous DIV's. ...
How do I add MouseEvents, specifically MouseOutHandlers to an AbsolutePanel without creating a Composite widget? Or is this possible? From what I can tell it involves adding a DomHandler, and a HandlerRegistration. A detailed example would be greatly appreciated considering I am quite new GWT and Java. Thanks, Eric ...

My problem is that I have to use a HTML template for all of my items, but I want to build GWT/Ext-GWT widgets instead, so I'm using div placeholders that I will replace with the proper widgets. How can I replace my div with a widget? my first attempt wa...
I'm having this problem with GWT when it's behind a reverse proxy. The backend app is deployed within a context - let's call it /context. The GWT app works fine when I hit it directly: http://host:8080/context/ I can configure a reverse proxy in front it it. Here's my nginx example: upstream backend { server 127.0.0.1:8080; } ...
I was going over the tutorials for GWT and was confused by this piece of code. The code is at GWT tutorials private void addStock() { final String symbol = newSymbolTextBox.getText().toUpperCase().trim(); newSymbolTextBox.setFocus(true); // Stock code must be between 1 and 10 chars that are numbers, letters, ...
The home page for gchart, a client side charting add-in for Google Web Toolkit (GWT), has a long screed about how the project's only maintainer thinks his Google account has been hacked and because of that he will be "disavowing/abandoning my own project and Google account". Does that mean the project is an orphan? Is somebody taking i...
I'm trying to call a web service in my back end java code when it's running in hosted mode. Everything loads fine, the GWT RPC call works and I can see it on the server, then as soon as it tries to call an external web service (using jax-ws) the jetty falls over with a Internal Server Error (500). I have cranked the log all the way...

Hi. I made in GWT custom modal message box. It has also bottom layer. This means that I expect restriction of any user action at the page except clicking 'Ok'. I made something like this (click on the 'show dialog box'). I have made bottom layer that covers all bottom controls. It has style: .glass { background-color: #000; op...
I've run into a rather annoying issue that is preventing from running any GWT projects (including unmodified wizard generate projects). Any project I try to run in hosted mode only generates HTTP 400 errors; I have turned all logging levels up as high as the will go and get the same output I would expect if everything was working fine. T...

When I add this composite widget to my panel I use a do while loop to pull data from an XML file and populate the composite data. When I instantia...
