Re: [eclipselink-dev] Error in EMQueryJUnitTestSuite.testcreateNativeQueryWithSelectSQL on SAP NetWeaver
|
Hi Sabine,
I am not familiar with how the entity manager for the tests are created. The
part of the spec you are referring to is for Transaction-scoped entity managers.
Is the entity manager used in this test created in such a way that it will be
transaction-scoped on all servers?

Hi,
I’d like to get your opinion on an error I get when running the JPA
server tests inside an SAP NetWeaver application server (stack
shortened, executed on current trunk):
java.lang.IllegalStateException: Attempting to execute an operation on a
closed EntityManager.
at
org.eclipse.persistence.internal.jpa.EntityManagerImpl.verifyOpen(EntityManagerImpl.java:1516)

org.eclipse.persistence.internal.jpa.EJBQueryImpl.executeUpdate(EJBQueryImpl.java:492)

org.eclipse.persistence.testing.framework.server.TestRunnerBean.runTest(TestRunnerBean.java:87)
I run the test against a MySQL database. The MySQL driver throws an
SQLException in EMQueryJUnitTestSuite line 114: Can not issue
executeUpdate() for SELECTs.
Consequently, I end up in the catch block where the current transaction
is rolled back.
Chapter 7.9.1 of the JPA specification says:
“After the JTA transaction has completed (either by transaction commit
or rollback), The container
closes the entity manager by calling EntityManager.close.”
Apparently, this is what the JPA container in NetWeaver does. With the
closed entity manager, however, query2 becomes unusable.
In my opinion, it’s an error of the test rather than of the JPA
container, but I might be wrong. What do you think?
Thanks and best regards,
Sabine
