[rules-users] Drools flow web console (5.1.M1) deployment in JBoss

[satjo]

I have set the data source. Following is the stack trace.

When I go to Settings->System->Overview, I see that
org.jboss.bpm.console.server.plugin.ProcessEnginePlugin is not green.

I must have missed something in the installation or copying a dependant jar
file. 


URL: 'http://localhost:8080/gwt-console-server/rs/process/definitions' 
Action: 'org.jboss.bpm.console.client.process.UpdateDefinitionsAction' 
Exception: 'class com.google.gwt.http.client.RequestException'
HTTP 500: 
HTTP Status 500 -
