Hey Guys,

I am working with J2EE since 1 month and now I want to use jBPM 5. I got a very nice example from here:

http://community.jboss.org/people/bpmn2user/blog/2011/12/18/jbpm5-web-example--local-human-task

But it does not work for me, because of the datasource I think.

When I deploy I get this error:

INFO  [org.jboss.as.server.controller] (DeploymentScanner-threads - 2) Deployment of "jbpmwebexample.war" was rolled back with failure message {"Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.jbpmwebexample.jbpmwebexample.env.datasources.jbpmDS missing [ jboss.naming.context.java.jboss.resources.datasources.jbpmDS ]"]}

I know where I can "change" this. In the web.xml

 <resource-env-ref>
    <resource-env-ref-name>datasources/jbpmDS</resource-env-ref-name>
    <resource-env-ref-type>javax.sql.DataSource</resource-env-ref-type>
  </resource-env-ref>

But I don´t know what I should write in...

I got a datasource configuration for a h2-database (installed with jBPM installer): java:jboss/datasources/jbpmDS

My persistence.xml look like this:
