I have now removed proxy="dynamic" from all my class descriptors and I
no longer get the exception.
After doing some testing. I am finding that sometimes I get the
exception, sometimes it works and sometimes the contactMech is
populated with an instance of CPhoneNumber (which is what i want) and
sometimes it just populates with CContactMech. CPhoneNumber extends
CContactMech. I have modified the code on the server to use class hints.
The only pattern I am finding is that I can retreive the
PartyContactMech without an exception if the obejct was created during
the life of the server process. If i start the server and retreive
one that was not created during the life of the process then I get the
exception. Sounds like it works fine when the objects are cached, but
thats just an assumption.
I also stopped using a the dynamic proxy for PartyContactMech.

I have a similar error when using. I am able to set fields with
other objects when retreiving them from the db. This particular
class is giving me some problems.

I get and IllegalAccess exception when ojb tries to populate a
reference to another object. I have no problems storing the
object. The exception is attached and below is my code and mapping.
----- Code --------
Integer partyId = (Integer) getParameter("partyId");
Criteria crit = new Criteria();
crit.addEqualTo("partyId", partyId);
Query query = QueryFactory.newQuery(CPartyContactMech.class, crit);
setParameter("partyContactMechs",
getBroker().getCollectionByQuery(query));
---- Exception ---------
