Hi,
In CMP Entity beans, fields that can not be mapped automaticaly to primitive
SQL type are
serialized and saved as Object in the database. One problem is then if you
want to change the Object, you have to take care of Serialization
versions,...
everything is not possible here. Another problem is if you want to give
access
to your db to a non Java world.
One solution for that could be to XMLize the object to a VARCHAR/String
format.
The power on changes of the Object will be more powerfull by implementation
of
method like "importXML" and "exportXML".
What do you think of a feature like that ?
What I try to avoidby using that is BMP , TopLink/Castor, XML/Object
Databases.
Vincent.
