    Use a tool which supports this like CoCobase from Thought inc.

    Weblogic uses Toplink to provide CMP. It is very vendor specific though, depends what kind of app server you are using.

    Yes, TopLink is very vendor specific and actually quite invasive to the application server. Thats why I like CoCo Base so much. Its not invasive, ports to every application server, and uses the EJB2 style CMP/BMP subclassiing model.

    We use it alot with Sybase EAServer
