anonymous wrote : Unabled to enlist resource, see the previous warnings This is coming from JBossTS TransactionManager used in JBoss 4.2.x, which is more strict about enlisting multiple resources in a single transaction than the previous implementation from JBoss 4.0.x. See http://wiki.jboss.org/wiki/Wiki.jsp?page=Multiple1PC for a discussion of this problem. To start with, I'd leave the jbpm.cfg.xml settings as they were and set the allowMultipleLastResources="true" switch in conf/jbossjta-properties.xml and see if you come around this issue. As this is not the recommended approach from a transactional perspective, you could then think of the other options as listed on the tx wiki and docs.
