[jboss-user] [JBossCache] - JBoss Cache (PojoCache) with Hibernate Collections (Persiste

[mleur]

Hi, 

I am using PojoCache to store Pojo Objects created by Hibernate.
I want to use the replication mode with this cache, so I pre-compile with aopc (ant task) my classes.

But when I call PojoCache.putObject with an Object (which contains collections) loaded by Hibernate, I have an exception :

I have done many tests, I have reproduced the problem without Hibernate.
In fact, the problem is the Hibernate implementation of Collections e.g: org.hibernate.collection.PersistentSet.

When I create an Object which contains other objets within PersistentSet, I cannot put objets into PojoCache and I have the same exception.

So, Could PojoCache work with Hibernate Objects and its Collection implementations ???

Thanks for Help.
