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)
at org.eclipse.persistence.internal.jpa.EJBQueryImpl.executeUpdate(EJBQueryImpl.java:492)
at org.eclipse.persistence.testing.tests.jpa.relationships.EMQueryJUnitTestSuite.testcreateNativeQueryWithSelectSQL(EMQueryJUnitTestSuite.java:121)
at org.eclipse.persistence.testing.framework.junit.JUnitTestCase.runBareServer(JUnitTestCase.java:463)
at 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
