[jboss-user] [jBPM] - Re: jbpm, process definitions, jboss - looking for knowledge

Piotr Tempes [http://community.jboss.org/people/carek] created the discussion "Re: jbpm, process definitions, jboss - looking for knowledge" To view the discussion, visit: http://community.jboss.org/message/597136#597136 -------------------------------------------------------------- one hundred thanks to you for this really great tutorial. I guess I'm now one step from reaching my target. However there's still one problem I can't handle - the persistence layer.  Maybe stack trace first: [code] [2011:03:90 22:03:122:info] ResourceChangeNotification created [2011:03:90 22:03:132:info] ResourceChangeScanner reconfigured with interval=60 [2011:03:90 22:03:132:info] ResourceChangeScanner created with default interval=60 [2011:03:90 22:03:132:debug] ResourceChangeNotification monitor added monitor=org.drools.io.impl.ResourceChangeScannerImpl@15a0305 [2011:03:90 22:03:134:debug] KnowledgeAgent building resource map [2011:03:90 22:03:135:info] KnowledgeAgent created, with configuration: monitorChangeSetEvents=true scanResources=true scanDirectories=true newInstance=true [2011:03:90 22:03:140:info] KnowledgeAgent has started listening for ChangeSet notifications (null: 3, 183): schema_reference.4: Failed to read schema document ' http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/...;, because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
