Hi everyone,

I am having trouble with XML encoding of a java application which uses hibernate. I get a null pointer on every serialisation attempt of my hibernate objects, and everytime a "EnhancerByCGLIB" is in the stacktrace.
I tried disabling cglib and using Hibernate.initialize(status); without success.
My mapping files were generated by MyEclipse - Hibernate Tools, should I modify them to disable lazy initialisation? There is about 50 or more mapping file so I'm not giving it a shot :(

I dont know where to look anymore, any advice would be great.

Hibernate version: 3.2

Full stack trace of any exception that occurs:

Quick reply, I finally found how to solve this with the following code :


// If this is a Hibernate Proxy, loads the object
if (this.operstd instanceof HibernateProxy) {
this.operstd = (Operstd) ((HibernateProxy) operstd).getHibernateLazyInitializer().getImplementation();
}

You may find more information on the forum by searching for HibernateProxy :)
