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

Friday, 23 October 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.

 Thanks for your response!
 It did fix the problem and I do not get the exception after I log in
 if I
 run org.drools.task.RunTaskService.

 I, however, get exception if I click on 'Process
 Definitions'->'Definition
 List'.
 Here is the stack trace.
