gwt-2.5

We are trying to build a GUI framework using GWT. We are finding it hard to implement the cancel functionality in the framework. Required feature is this: We have CRUD screens which have pop-ups, grids and so on.

I've started taking advantage of GWT 2.5. The coolest feature of GWT 2.5 was the ability to write Java code directly in our HTML pages like so: <script type="text/java"> String helloWorld = "Hello world"; Window.alert(helloWorld); </script> The trick is to use a ServletFilter on the server side.

I'm using GWT 2.4 & Eclipse Juno. GWT is installed using the instructions at https://developers.google.com/web-toolkit/usingeclipse . I'd like to try GWT 2.5. How do I upgrade from GWT 2.4 to 2.5? Currently, GWT 2.5 is only available as a Release Candidate, and as such is not delivered via the usual Eclipse update site yet. However, it's easy to use Eclipse with any GWT version: Download the GWT SDK(s) you need from https://developers.google.com/web-toolkit/versions Extract it anywhere you like In Eclipse Preferences > Google > Web Toolkit, use the "Add..." button and navigate to the GWT SDK
