Hi Friends,
I am looking for good reference for Advance Hibernate Mapping where I can read more about Composite ID other then this web sites. Also I want to know more about hibernate and struts. Currenlty I am working on most complex screen where my one table had 4 fields as composite primary key and all there fields point to other modal object to get more information. So i have to use composite id and some more complex queries. So plz somebody suggest me any book or website for more refrence.

Thanks
