Attached is my working copies of what you want with a little difference. I use uni-directional relationship from user to role. I wonder why you want a bi-directional one. Besides, you cann't do cascade delete unless the other side of the relationship has a multiplicity of one. That is to say, in your case of n-m relationship, you cann't do this. You might need to adust your requirement a bit. Also I use value object generate by XDoclet, if you don't use it, just comment out the value object tag both at class level and method level.
Hope it helps. guo --- "R. P.
