hello,
i´ve read the documentation. i changed the web.xml files in the following locations:
\task-service\target\war
E:\jbpm-installer 5.3\task-service\resources\war
and as part of the war file:
\jboss-as-7.0.2.Final\standalone\deployments
i entered 'hornetq' in all of them. unfortunately, the problem stays the same.
:(
