Eclipselink assumes erroneous NoPlatform when target-server not set [message #1778898] Sat, 23 December 2017 08:16 Go to next message

Hello,
I use an own PersistenceProvider which is a wrapper around EclipseLink provider (2.7) in a JTA persistence unit on Tomee 7.0.2. Now eclipselink.target-server is not set by Tomee in PersistenceUnitInfo and EclipseLink sets NoServerPlatform which disables JTA. This is definitely wrong as the persistence unit is of transaction-type JTA. As a consequence I get TransactionRequiredException even if within a JTA transaction.

Proposed improvement: when transaction-type is JTA and eclipselink.target-server is not set, instead of silently setting NoServerPlatform an Exception should be thrown indicating that eclipselink.target-server must be set explicitly.
It took me a lot of hours to drill down the Eclipselink code to find this out.
thanks

Additional observation in Glassfish 4.1.2: Here a NullpointerException is thrown explicitly in the code if eclipselink.target-server is not set:
java.lang.NullPointerException
	at org.eclipse.persistence.platform.server.ServerPlatformUtils.createServerPlatform(ServerPlatformUtils.java:99)
	at org.eclipse.persistence.sessions.factories.SessionManager.init(SessionManager.java:77)
	at org.eclipse.persistence.sessions.factories.SessionManager.<clinit>(SessionManager.java:71)
	at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.addSessionToGlobalSessionManager(EntityManagerSetupImpl.java:907)
	at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.initSession(EntityManagerSetupImpl.java:2671)
	at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.deploy(EntityManagerSetupImpl.java:675)
	at org.eclipse.persistence.internal.jpa.EntityManagerFactoryDelegate.getAbstractSession(EntityManagerFactoryDelegate.java:205)
	at org.eclipse.persistence.internal.jpa.EntityManagerFactoryDelegate.createEntityManagerImpl(EntityManagerFactoryDelegate.java:305)
	at org.eclipse.persistence.internal.jpa.EntityManagerFactoryImpl.createEntityManagerImpl(EntityManagerFactoryImpl.java:337)
	at org.eclipse.persistence.internal.jpa.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:303)
	at org.glassfish.persistence.jpa.JPADeployer$2.visitPUD(JPADeployer.java:451)

In Glassfish/Toplink, additionally toplink.target-server must be set to the same value as eclipselink.target-server (SunAS9).
Please be a little more kind to us and give some more information in Exceptions and not only throw a NullPointerException if a required property is missing. Thank you
