Description of problem:

Section does not mention the need to add a datasource in EAP 6x. Out of the box EAP 6x only has a database named ExampleDS.  The BRMS EE6 deployable package is preconfigured for a HSQL database named jbpmDS. 

Recommend documentation describing:
1) Pointing to documentation for creating a datasource in EAP 6
2) Configuring the datasource name and dialect in:
     jbpm-human-task.war/WEB-INF/classes/META-INF/persistence.xml
   and
     business-central-server.war/WEB-INF/classes/META-INF/persistence.xml
