It's a dynamically-generated subtype of whatever type that you specify in the field declaration. So, you need to have a no-args constructor and the class can't be final. If you declare the field to be an interface type and you don't initialize the field to anything, I don't remember how we decide what impl to use. -Patrick _______________________________________________________________________ Notice: This email message, together with any attachments, may contain information of BEA Systems, Inc., its subsidiaries and affiliated entities, that may be confidential, proprietary, copyrighted and/or legally privileged, and is intended solely for the use of the individual or entity named in this message.
