Re: [rules-users] Unable to start drools-server 5.1.1 or 5.2.0.M1 under Tomcat 6.0.30

I'm just using a stock build from http://www.jboss.org/drools/downloads.html, and it has <drools:execution-node> defined in 5.1.1. When I remove it, I just get a error on the next xml tag. I tried again with the JBoss AS included with Drools Guvnor Standalone 5.2.0.M1, copying drools-5.2.0.M1-server.war to jboss-5.1.0.GA/server/default/deploy/drools-server.war, but get the following error: 14:19:57,160 INFO [PersistenceUnitDeployment] Starting persistence unit persistence.unit:unitName=#org.drools.grid 14:19:57,165 ERROR [AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=#org.drools.grid state=Create java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: org.drools.grid On Mon, Feb 28, 2011 at 4:04 AM, Esteban Aliverti < esteban.aliverti(a)gmail.com&gt; wrote:
