[rules-users] Debuggin in Eclipse

[Kris Verlaenen]

Have you tried creating a new empty project (but similar to the one
you're using, not sure which type of project you have created, like a
normal Java project or a J2EE project or whatever), convert that to a
Drools project, add a simple hello world rule and try to debug that? 
Being able to reproduce this on a rather simple project would probably
allow me to take a deeper look into this.
