    Correct me if i am wrong.

     I have read CMP Entity beans do not map to multiple tables.

    Regards

    hi chandra

    can you explain what you mean by working with multiple tables ?
    If you are talking about multiple joins ..none of the appservers have a full fledged cmp.
    they use a 3rd party persistence mgr viz
    CocoBase from Thought Inc
    or
    Toplink from (cant recollect)

    DOnt know if this helps
    Thanks

    One option is to use database view and a CMP bean.

    Hi,

    There is a catch using views over multiple tables in most databases, we cannot update/insert views, we can just select from them. So i guess view with one CMP may not work.

    u may use BMP(preferably) or a CMP with java objects as references that can have methods like load and save u can call from your bean's callback methods.

    Thanks!
