I am trying to instantiate a process instance based on a process definition for JBPM 5.1
from a EJB deployed in the JBoss application server. The EJB is part of a .ear file ,
using the MySQL database.
I have defined a persistence unit in persistence.xml within the META-INF folder and also
placed the corresponding JBPMorm.xml in the META-INF folder. The datasaource is deployed
in the deploy folder of JBOss 5.1

</local-tx-datasource>
</datasources>
When i deploy my .ear file
App Server is able to recognise the datasource, persistence unit for jbpm datasource from
persistence.xml and corresponding jbpmorm.xml.
However I get the exception : javax.persistence.PersistenceException: [PersistenceUnit:
org.jbpm.persistence.jpa.secureall] Unable to build EntityManagerFactory
On looking into the details for it I understand that EntityManagerFactory needs to be
loaded by the name: org.jbpm.persistence.jpa.secureall
Something like:
|
|
| EntityManagerFactory emf = |
|
|
| Persistence.createEntityManagerFactory(
"org.jbpm.persistence.jpa.secureall" ); |
|
|
| Environment env = KnowledgeBaseFactory.newEnvironment(); |
|
|
| env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf ); |
|
|
| env.set(EnvironmentName.GLOBALS, new MapGlobalResolver()); |
However I am not sure how do i define EntityManagerFactory by that name such that it gets
loaded by that name during deployment rather than during run time.
