No ClassLoaders found for: org.jboss.envers.event.VersionsEv

toby451 Feb 10, 2009 2:29 AM

Hi,

Oddly, I am having problems getting the envers-jar picked up by our application. The application is a rather big seam + hibernate search ... thing. Eventhough I ensure that the envers-jar is put in the lib of the ear I get:

Any ideas?
I would be very thankful.

Hello,

are you also bundling Hibernate with your app?
If not, then you are using the version bundled with the app server. Then you must put the Envers jar next to the Hibernate jars (so in server/default/lib).

However, 3.2.4.sp1 is quite an old version of Hibernate, which won't be supported by Envers in the future, so I would recommend updating to Hibernate 3.3.1. You can do that by simply bundling the jars with your ear.

Thanks for the reply. I'll give it a try.

I am not sure how well Hibernate 3.3.x works with jboss-4.2.3.GA and seam 2.1.0.GA though. I have had troubles upgrading before ... for other reasons ... see this post of mine: http://www.seamframework.org/Community/HibernateSearch310GA

Maybe you have any good insights into how to proceed given the the app server version + seam version?

Thanks anyway ... looking forward to swap out our own entity versioning in favor of yours.

I did some Seam+Hibernate applications, and when upgrading I think I just bundled the new JARs and that's it - don't remeber having any problems. The only thing is that you need to add a slf4j-log4j jar, but apart from that, nothing I think.

Perfect thanks! Finally I got it all working.

(A small note which you might be aware of already: When creating the schema using Ant there are really some cryptic messages (NPE on CollectionMetadataGenerator.addOneToManyAttached) when all I seemed to have missed was to add an @Audited on the child-entity).

Really?

That shouldn't be like this ;)
Can you please create a JIRA bug for that?

Thanks,
