Hi!

I am using JPA on a JBoss 4.2 GA and the underlying Hibernate version is v3.2.1. My RDBMS is MySQL 5!

I have an EJB 3.0 Entity bean and it has 2 relationships of type OneToOne . Fetch Type Eager. 2 diffrent tables

Code:

    @OneToOne(cascade={CascadeType.ALL}, fetch=FetchType.EAGER)
    private ClassA insA;
    
    @OneToOne(cascade={CascadeType.ALL}, fetch=FetchType.EAGER)
    private ClassB insB;

Μy application wont deploy if both of these relationships have EAGER Fetch type

Code:

Caused by: org.hibernate.HibernateException: cannot simultaneously fetch multiple bags 

Ι am aware of the same proble regarding OneToMany relationships and the proposed solutions , according to this post and several others!

That means that the problem now must be known to OneToOne EAGER relationships as well?

Of course if I make Lazy one of them or remove one of them the app is being deployed!

Any hints would be much appreciated!
