[rules-users] Drools flow web console (5.1.M1) deployment in JBoss

Fri Oct 23 14:24:08 EDT 2009

You pointed out the exact issue. This was what happened. I was using
defaultpackage of Guvnor, thinking it refers to the "default". 

After I created the new package called "default" and uploaded the
definition, it worked fine and it did not throw any exception.
