david zhang commented on OPENJPA-91: ------------------------------------ Hi, Patrick, what kind of DB2 driver info we should put into the config? DB2 connection pool driver class name? > java.lang.VerifyError on websphere after application reload > ----------------------------------------------------------- > > Key: OPENJPA-91 > URL: https://issues.apache.org/jira/browse/OPENJPA-91 > Project: OpenJPA > Issue Type: Bug > Environment: Using OpenJPA (openjpa-all-0.9.6-incubating.jar) in > Rational Developer 7 ( Websphere 6.1 test environment ) connected to Oracle > 9.2 database. > OS: WinXP SP2 > Reporter: Anders Monrad > Priority: Minor > Fix For: 0.9.8 > > > Hi .. > Not sure if this is a bug or just the way websphere reacts to openjpa. > I have a small test program using OpenJPA against an Oracle database. I am > running this program in the Websphere 6.1 test environment included with > Rational Developer 7. This is all working just fine. But when I make changes > to some ressource in the application, the chagnes are automatically published > to the test environment and the app is restarted. After this I get the > Exception below, whenever I try to access an EntityManager. > If I restart the entire server, the app is running fine again. So I guess > this is related to restarting the application. > Caused by: java.lang.VerifyError: class loading constraint violated (class: > org/apache/openjpa/kernel/BrokerImpl method: > newQueryImpl(Ljava/lang/String;Lorg/apache/openjpa/kernel/StoreQuery;)Lorg/apache/openjpa/kernel/QueryImpl;) > at pc: 0 > at java.lang.J9VMInternals.verifyImpl(Native Method) > at java.lang.J9VMInternals.verify(J9VMInternals.java:59) > at java.lang.J9VMInternals.initialize(J9VMInternals.java:120) > at java.lang.Class.forNameImpl(Native Method) > at java.lang.Class.forName(Class.java:131) > at > org.apache.openjpa.conf.OpenJPAConfigurationImpl.class$(OpenJPAConfigurationImpl.java:65) > at > org.apache.openjpa.conf.OpenJPAConfigurationImpl.<init>(OpenJPAConfigurationImpl.java:182) > at > org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.<init>(JDBCConfigurationImpl.java:110) > at > org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.<init>(JDBCConfigurationImpl.java:100) > at > org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.<init>(JDBCConfigurationImpl.java:91) > at > org.apache.openjpa.jdbc.kernel.JDBCBrokerFactory.newInstance(JDBCBrokerFactory.java:55) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:615) > at org.apache.openjpa.kernel.Bootstrap.invokeFactory(Bootstrap.java:117) > at > org.apache.openjpa.kernel.Bootstrap.newBrokerFactory(Bootstrap.java:57) > at > org.apache.openjpa.persistence.PersistenceProviderImpl.createEntityManagerFactory(PersistenceProviderImpl.java:70) > at > org.apache.openjpa.persistence.PersistenceProviderImpl.createEntityManagerFactory(PersistenceProviderImpl.java:78) > at > javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83) > at > javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:60) > at > util.EntityManagerFactoryHelper.getEntityManagerFactory(EntityManagerFactoryHelper.java:22) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
