Finally...some magic was able to resolve the issues within guvnor by creating
some skelton classes for the util methods i was using from decision
tables...

When I try to access the package from java...it gives me...

[2010:01:11 13:01:356:info] KnowledgeAgent new KnowledgeBase now built and
in use


Is this due to my skeleton packages ? Why should I get a deserialization
exception ?

Thanks
