Hi I'm a beginner with JBoss, jBpm, Drools and stuff. We have a simple jBPM process and drools rules. We are unable to integrate both. Getting many errors. We r getting WorkingMemory not found error. And when we used KnowledgeBuilder we are getting the error: builder.add:no such method not found. We have set the class path with all the required jars too. Please help us out.
