Subject Re: [jira] Commented: (OPENJPA-91) java.lang.VerifyError on websphere after application reload
Date Tue, 10 Apr 2007 17:29:11 GMT
This has been commented on before.

You need to rerun the Enhancer on any Entity classes that are 
re-published and stop and start WebSphere.

It is best to turn off automatic publishing in WebSphere/RAD.

You can still run it in debug mode under RAD and change anything other 
than Entities without needing to restart.  I do this all the time.



>> Hi ..
>> Not sure if this is a bug or just the way websphere reacts to openjpa.

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.

related to restarting the application.
