Damn, the DroolsFlowCommandDelegate seems to be swallowing the
exception, as the exception caught there is not added as the root of the
thrown exception (line 68). There's no stack trace of a
NullPointerException in the log (right) before this error?
I also fixed this on trunk, so the caught NullPointerException is added
as the root cause now, so the stack trace should now contain the trace
of the NPE as well. If there's no NPE in the log, could you update your
code from SVN, rebuild the wars, try again and send me the stack trace
again?

I have set the data source. Following is the stack trace.
When I go to Settings->System->Overview, I see that
org.jboss.bpm.console.server.plugin.ProcessEnginePlugin is not green.
I must have missed something in the installation or copying a
dependant jar
file.
