Hi all,
I'm using hibernate 2.1.3 and jdk 1.4.2_05. I know that there might be a solution in hibernate 3.0, using getEntityName() in the interceptor.

Can anyone confirm that it will work with implementing the interceptor with getEntityName as well?
-------------
I'm integrating hibernate with spring's acegi (security framework). I want to add security checks on a persisted objects methods.
Becuase it is spring, I add a proxy (dynamic or cglib) with in front of the actual method. This all works fine but when use it together with load runner. The class is of course different.
Hibernate complains that it does not have a persister for the specific class.

What I do in detail, is that in the instantiate-method in hibernate's interceptor:
-----
public Object instantiate(Class clazz, Serializable id) throws CallbackException {

create object with a spring proxy in front
return the object.

}

Later when it loads it I get the error:
net.sf.hibernate.MappingException: No persister for: no.abmu.organisationregister.domain.LanguageImpl$$EnhancerByCGLIB$$ffe2eb75

at net.sf.hibernate.impl.SessionImpl.find(SessionImpl.java:1544)

Of course not really surpringsly but I expected to solve this somehow, but I have to admit that I'm stuck.

The problem is general in the sense that it would be nice to add a dynamic proxy to a persistent object for other reasons than the above.

Does anyone have any suggestions?

I know that there are a number of workarounds but this will be by far the most simple.
