I am converting my jBPM 4.4 code over to use 5.0.1 and am trying to configure
persistence. When I run my unit tests to see if everything is working as it did in 4.4 I
am getting this error:
No Persistence provider for EntityManager named org.jbpm.persistence.jpa
See the end for the full stack trace. I have been following the user guide and configured
a datasource.xml file and set up the EntityManagerFactory and used it in the creation of
the KnowledgeSession. What am I still missing? Any help would be appreciated.
Jim
EntityManagerFactory emf =
Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
Collection<StatefulKnowledgeSession> ksConfigs =
kbase.getStatefulKnowledgeSessions();
if (!ksConfigs.isEmpty()) {
KnowledgeSessionConfiguration[] sessionArray =
(KnowledgeSessionConfiguration[])ksConfigs.toArray();
if (ksConfigs.size() == 1) {
sessionConfig = sessionArray[0];
}
if (ksConfigs.size() > 1) {
throw new Exception("More than one KnowledgeSessionConfiguration" +
" object exists. We were only expecting one");
}
}
if (ksession == null) {
ksession = kbase.newStatefulKnowledgeSession(sessionConfig, env );
}
