The Problem GWT (Google Web Toolkit) allows compiling Java into JavaScript source. I like to use it to create client-only JavaScript applications (this can be very useful for testing purposes). The GWT compiler will place all the compiled JavaScript sources in your project directory and the applications can be tested
Widgets in GWT are essentially elements in the DOM tree of a web document. GWT widgets enable convenient control over these elements. For instance, a call of the widget method setSize(String width, String height) will set the dimensions of the HTML element underlying the widgets. Values to define the
It seems in the Session List for Google I/0 2011 there is no easy way to see all the Google Web Toolkit (GWT) sessions in one glance. So here is a quick overview: GWT and Ui GWT + HTML5: A web developers dream!, John Labanca GWT + UI Designer: Enterprise Web
Problem It is quite easy to deploy application to a Tomcat instance using the Tomcat manager (usually accessible under the url /manager). However, by default the applications are available under a path equal to their WAR file name: e.g. an application 'test_application.war' would be available

The Ext GWT framework offers some rather sophisticated support for drag and drop in GWT applications. However dealings with drag and drop in TreeGrids can be complicated at times, since only limited documentation apart from the examples in the showcase is provided. Here some information, how it can be controlled,

If there are multiple dependent projects in an eclipse workspace, it can be tedious to run the unit test of all these projects manually. Often, a failed unit test caused by a change in a different project than where the unit test is located is only discovered with a significant
The question of the right programming language is one that has always spurned much controversy. Likewise, the idea that one day we could develop software by simply 'drawing' expressive models has as many advocators as opponents. The idea of domain specific languages could be one which helps us
Ubiquitous devices of all sizes have radically changed our reading experiences in the last couple of years. I have no problem in reading entire books using iBooks on the iPhone. Reading on the iPad has often been criticized for the potential strenuous effects of screen brightness. However, I most struggle
There are a number of plugins for eclipse, Maven and/or subversion, which allow the convenient and automatic determination of important project statistics such as the total lines of code in a project or the number of Java classes. However, sometimes one just needs these statistics quick and dirty and
Problem Java lists manage inserted objects based on their equality (see List JavaDoc).
