Error Description : Error when creating container TestProjectEIEI_1.5 by extension jBPM KIE Server extension due to datasources/EIEIMYSQL -- service jboss.naming.context.java.jboss.datasources.EIEIMYSQL.

I am wondering whether I am missing any other configuration steps for external data Persistence objects. If so Can you provide the steps ?
