Subject [jira] Commented: (OPENJPA-91) java.lang.VerifyError on websphere after application reload
Date Fri, 22 Dec 2006 21:07:21 GMT
    [ ] 
Igor Fedorenko commented on OPENJPA-91:

Also, how do you configure database connection? Do you use WAS datasource or tell OpenJPA
driver/connection details? In the latter case, are you using type2 or type4 driver (hint:
switching to type4 might help).

> 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;)
