Following the above instructions, I can create an application and run
it as a GWT Web Application (which is a bonus). If I try to Debug As -
> Web Application I get problems. At debug startup Eclipse complains
that the source attachment does not contain the source for the file
URLClassPath.class. The debug session is suspended with a
FileNotFoundException. Here's the call stack from the Eclipse's Debug
window:

I have to click resume about 10 times before it'll properly start up.

I have completely wiped out my Eclipse workspace and recreated/
reimported the project and the same thing happens.

Any ideas?

Thanks,

Pete
