Subject [jira] Commented: (OPENJPA-384) ClassCastException when trying to load OpenJPA 1.0.0 based webapp in WebLogic 10
Date Tue, 11 May 2010 17:16:40 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12866212#action_12866212
] 

David M. Karr commented on OPENJPA-384:
---------------------------------------

Does anyone know if this works any better if you use the OpenJPA 2.x release?  I'd hate to
have that be my main reason for upgrading the OpenJPA release, but it would be good to know
if that would make a difference.

> I am trying to deploy a web application which uses OpenJPA 1.0.0 into a WebLogic 10 environment.
The application deployment (and subsequent startup) fails with the following error:

versions of OpenJPA under WebLogic 10 (which packages OpenJPA 0.9.7 as part of Kodo).
