Subject RE: how to adjust classpath - version 3.1.2
Date Tue, 26 Oct 2010 14:45:19 GMT
Thanks, I added backport jar to my testing lib, and openejb works fine. What confused me is
my ear without this jar can still work fine in the Weblogic server (and I searched Weblogic
and I didn't find a backport jar there). Could it be the way HibernatePersistence invoked
by openejb somehow different from when it's loaded from the server that made the difference?
I agree with you on Hibernate/EHCache seems to be using it of course.
 
Regards,

Trimmed down the stack trace to the 'Caused by' clause and it looks Hibernate/EHCache related.

My guess is you need this jar: http://backport-jsr166.sourceforge.net <http://backport-jsr166.sourceforge.net/>


We used to include that in 3.1.2 as it was needed by ActiveMQ 4.  Now we use ActiveMQ 5 and
that jar is no longer required for any code we ship, but it looks like Hibernate still uses
it via EHCache.
