Hi
I can think of any other reason as all I am doing is executing a query.
The service is defined as
@WebMethod
public List<AccountType> queryAccountTypeFindAll() {
return em.createNamedQuery("AccountType.findAll").getResultList();
}
The AccountType object has a reference to an a Collection of type
EntityAccountInformation and each instance of EntityAccountInformation has a
single reference to AccountType.
I don't know what I have done wrong here. Never seen this before to be
honest (this error that is) will dig deeper and see what I come across.
Thanks for the input thus far

Are you sure that the exception comes from the query? It seems like an xml
processing error.
thanks,
