[rules-users] Building a rule base from the content of a directory

[Bruno Freudensprung]

Hi Toni,

Thanks a lot for your investigations. What I've noticed so far is: when 
you add a "drools.package" file in the KnowledgeBuilder (as a DRL 
resource), then add the BRL file in the KB (as a BRL), the KB has 
errors. When both are concatenated then added (as a DRL) it works well.
Best reagrds,

Bruno.
