GWT communication problems

Hi
this helps a lot, and i updgraded it, but the thing with another project doesn’t seem to work. I exported a gwt project into a jar and added it to my pom.xml because i am using maven. Then I clicked on the compile widget button and he compiles only the files for the default widget set and not for my specific gwt widget. In my .gwt.xml there is only the user agent property and the inheritance for the default widget set.
In earlier version there were a lot more inheritance tags, for inheriting external jars.
A step by step tutorial would be perfect if one exists,if not any other help is useful, too.
