[rules-users] Drools get value from stateful session

[Wolfgang Laun]

Digging a bit into Java's API always helps ;-) Note that
Class.getSimpleName() really does what it says, as opposed to
Class.getName().

It would be best to avoid the String representation:

Collection findFacts( StatefulKnowledgeSession session, Class factClass ){...
public boolean accept( Object object ){
   return object.getClass().( factClass );
}...}
