Subject [jira] Updated: (OPENJPA-91) java.lang.VerifyError on websphere after application reload
Date Tue, 02 Jan 2007 13:17:27 GMT

]

Anders Monrad updated OPENJPA-91:
---------------------------------


I am using the type 4 driver, so there should not be any problems with native code. I tried
to add the libraries as a shared library in WAS6.1 but had the same issue.

Now I added the OpenJPA libraries to the <was61>\lib\ext library, and restarted the
server. This seems to be working!

> 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;)
