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

Thu Oct 22 21:30:43 EDT 2009

When you uploaded your sample process to Guvnor, did you add it to the
"default" package (notice that the name should really be "default", and
not "defaultPackage", which is created in Guvnor by default)?  And after
adding the process to the package, did you build the package on Guvnor?

The NPE seems to indicate that it cannot find the knowledge base for
package "default" on Guvnor.
