Hibernate stops working when app is redeployed

[daborg]

Hi,

We have a problem with Hibernate on JBoss 3.2.3.

When we redeploy our application, Hibernate stops working.

More specifically, we get this error when trying to access Hibernate objects:

"net.sf.hibernate.MappingException: No persister for: <persistent object class>"

To get it working, we have to restart JBoss. This is obviously a pain in the neck.

Does anyone have any ideas what could be causing this problem?

Any help would be gratefully received!

I saw a similar problem with cglib hanging onto old classes.
Is cglib in your application or server/default/lib?

I'm having the exact same problem as daborg, Hibernate 2.1.5, JBoss 4.0.1

I've tried it both with the hibernate and related jars in both /lib/ and inside the sar i'm using to deploy hibernate (which itself is in an EAR)

Is there a fix / workaround / solution to this problem?

(oops, I guess angle brackets in posts aren't a good idea, anyway, to continue...)

I've tried it both with the hibernate and related jars in both the server/lib/ dir and in the SAR file i'm using to deploy hibernate (which in turn is contained in an EAR)

Is there a fix / workaround / solution for this at all??

i've redeployed hibernate in a HAR archive in my application.. and also tried deploying it outside of the application EAR... still no joy at all

here's a stacktrace (of sorts):

Any ideas? Should I open a bug on this?
