If I have tableA with id "a_ID" and tableB with id "b_ID" and property "b_PROP" and many to many lookup table with properties "a_ID" and "b_PROP" is there any way I can map this many to many relationship with Hibernate?

My understanding is the collection key would have to be "a_ID". The column property in the many to many association would be the "b_prop" of the lookup table, but I don't see where I can stop it from using b_ID when linking to tableB. Can I use collection index for this or is this just not doable?

Thanks,

Have a look at property-ref attribute. I don't know if it will fit you needs, anyway.
