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

[Rafal Rusin]

Hello,

I have similar problem while listing processes in gwt-console - 'Could
not initialize stateful knowledge session'.
I tried to go through manual to set up drools flow with humantasks. I
basicly went through
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch14.html#d0e3588
.
But I get this exception (listing human tasks works well):

org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException:

Detailed logs are in attachment.
I compiled 'default' package containing example flow in guvernor, but
this didn't help.

I think that guvnor.war doesn't use testDS1 datasource, so I suppose
it writes SessionInfo object somewhere else. Do you think I could
reconfigure jackrabbit to use testDS1 datasource? Does that make
sense?
I used http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk@30785
version from Sun Dec 20 18:50:08 2009. I deployed things on JBoss
5.1.0.GA.
Do you have some ideas why this doesn't work?
