It turns out, there are quite a few places on the web to practice your Java skill level.
First I found out about http://codeeval.com/ .
I tried to do a puzzle just for fun and to see how the site is (code is not optimized or anything, just trying out their UI) :).
At the end there are some screenshots.
At the below link you can read a very interesting report about the future of GWT.
I’ll write another post with opinions if I have any (or time 🙂 ).
This post will explain the cause of this exception and provide an easy fix – with no need to add extra jars to your classpath or manually manipulate your jars.
I first saw this exception when I upgraded a project from GWT 2.4 to GWT 2.5.
The project also uses GXT 2 and 3 running side by side.
After the upgrade I saw this in the logs:
Caused by: java.lang.NoClassDefFoundError: com/google/gwt/core/client/GWTBridge
