We are receiving an Persistence error while building a busing a project for external data source. Please see the details of the error ,  Persistence configuration, Marshaling settings   of the Project.

The version we are using  is JBPM Version 7.17.0.Final and Apache Software License 2.0

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 ?
