Or.. you could use TopLink For Weblogic to do real mapping of dependant
objects.
Or in fact use one of several App Servers which support mapping of dependant
objects from within
a CMP bean, some of these make use of Weblogic as well: PowerTier,
Websphere, Voyager Application Server, etc.

If you really, really want to use CMP with a dependent object in an entity
bean, consider the following steps.
* Define a byte[] field in the CMP entity bean sufficient to hold the
dependent object in serialized form
* in ejbStore(), serialize the dependent object to the byte array
* Container stores byte array to database column. Dependent object is not
mapped, only the byte array is.
......
* Container loads cmp fields from database - including byte array
* your ejbLoad() processes serialized object and writes to dependent object
In other words, use ejbLoad and ejbStore to transform the dependent object
into a form compatible with weblogic's simple container managed persistence
capability.
If you can convert the dependent object to/from a string, you can use that
instead of a serialized object.
There is definitely a performance hit with this approach but it does allow
the use of CMP.

Ive worked only with Weblogic 5.1. With Weblogic, it is not possible
to implement an Entity bean with dependant object as a CMP bean. You
should have to go for BMP.
