Re: [drools-user] Dynamically Generated Classes as JBoss Rules Facts

Other thing that may be useful is that before loading the generated 
class I've tried this:

ClassFieldInspector cfi = new ClassFieldInspector(c);

and a "Class not found" is thrown.

I 've also tried the approach based on changing the compiler to JANINO, 
but I got the same errors.
