Hi there! I have a ManyToMany relation between ClassA and ClassB, defined in the following way: ClassABean.java: | @ManyToMany | @JoinTable(name="a_b", | joinColumns=@JoinColumn(name="aid", referencedColumnName="id"), | inverseJoinColumns=@JoinColumn(name="bid", referencedColumnName="id")) | public Set<ClassBBean> getMyBs() | ClassBBean.java: | @ManyToMany(mappedBy="myBs") | public Set<ClassABean> getMyAs() | The problem is that when I try to delete a ClassB entity, it fails with the violation if an integrity constraint (child record found). If I put a CascadeType.ALL in the ClassB definition, it deletes the corresponding ClassA entity, even if it has other associations... What I want is to just delete de ClassB entity! Can anyone help me? What am I missing? Thanks a lot in advance, AP View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139346#...
