I want to style this program and to do so, I'd like to have all of my elements become s so I can CSS style them properly -- can someone tell me how to go about doing that? Are there widgets in GWT that don't use tables, e...

In an attempt to get my old GWT project working again with GWT 2.0, I created a default GWT 2.0 project in Eclipse and was able to run it successfully.

Hi When using GWT I get following warning: Referencing deprecated class 'com.google.gwt.user.client.rpc.SerializableException' While it's only a warning, it's dead annoying having to look at every single time I run the project.

For example, consider the following events: A user requests a deletion of data, however, due to it's long-running time, we kick it off to a queue. The client receives a "Yes we completed your transaction successfully". The server delet...
I'm looking for Java rules engine options that will allow me to use the same rules in a server side backend, a GWT frontend, and JavaME apps. I'd also love to hear about the pitfalls of attempting to do such. The motivation is a push to use a rules engine in a server side code base that I am concerned may cause a schism between validati...
