Hi,
do you use jbpm-installer? It should work out of the box there.
If you deploy jBPM .wars into JBoss AS, you have to configure several things by yourself. In this case you need to modify $JBOSS_HOME/standalone/configuration/standalone.xml in this way:
| <subsystem xmlns="urn:jboss:domain:ee:1.1"> |
| <global-modules> |
| <module name="org.jboss.netty" slot="main"/> |
| </global-modules> |
| <spec-descriptor-property-replacement>false</spec-descriptor-property-replacement> |
| <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement> |
| </subsystem> |
