Hello

I'm using Hibernate 2 in JBoss.
hibernate2.jar and all 3rd party libs are in server/default/lib.
when JBoss is started fresh and application is deployed first time, it's OK
when I work with app and then redeploy it, I'm getting the following exception

net.sf.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.vocognition.project.ige.domain.IgeSessionState.setMission

when I set hibernate.cglib.use_reflection_optimizer=false, it looks like this

all these problems DISAPPEAR when I put hibernate2.jar and 3rd party libs in same EAR
however it's not convenient because "recompile-redeploy" time of <10 seconds becomes >30 seconds

is there any good way around this?

thanks in advance

I do not see the cause, but I think it is ClassCastExeption.
You need to drop old configuration after reploy and to configure a new SessionFactory,
I think it stores references to old model classes and it will cause memory leaks too, if you do not redeploy hibernate itself.

BTW, try to develop outside container, it is one of the most useful hibernate features (POJO and testability).

Check the forum, somebody has the same problem recently. I can remember it's a JBOSS bug solved in the CVS (You'll have to check to be sure).
