Shreedhar, Sanjeev, The EJB 1.1 spec did not explain relationship semantics and how they should be implemented. However, our (EJB 1.1)Container does support relationships in pretty much the same way that the 2.0 spec defines the relationship semantics. Take a look at: http://www.borland.com/techpubs/books/appserver/appserver45/ejb-programmers/entity-beans.html#999808 for more details.
