After some more tinkering and searching, I realized that I had not installed the required grails plugins. So after installing gwt-grails and hibernate for good measure, and updating GWT-Ext (was complaining about something) it actually works. Although its not displaying anything and I get lots of "[WARN] Deprecated use of gwt.typeArgs for field children; Please use java.util.ArrayList as the field's type" errors... I'll try inside eclipse now :) thanks. Ahh, forget what I said above.

So, I take it that you developed it in eclipse, judging from the remnants that it leaves. Sadly however, I cannot get it to work inside eclipse, and not even outside of eclipse in a shell. When I run grails run-app I get a bunch of errors telling me that groovyc can't find the com.gwt.* classes (although I'm asking myself why it tries to compile the client-side .java files in the first place). As for inside eclipse: I have the groovy plugin for eclipse installed, and even GWT-tooling support, but nothing works. After fixing all the imports for grails, groovy and GWT in my build path, I can start the 'findme' run conf, but get a NullPtrEx from within GrailsMain.main. And I have absolutely no idea whats going on... Do you have any helpful ideas or pointers? Thanks. I guess my next step is to try to rebuild your example from scratch, using above steps... lets see if that works ;) Hey there,
