The org.jbpm.db.jmx.JbpmService seems to have moved to org.jbpm.jmx.JbpmService and the own subproject jboss. This I think is a good idea to better sperate the JBoss stuff from jbpm core.
Nevertheless, the build-file in jboss/jmx is not working. To get the jar I needed I have added some lines in the build file (mainly copied from the identity build file) and one property in the build.properties:
yes. ok. i'll have a look at it later on.
thanks for the update!
