How to map MySQL Blobs/Clobs in Weblogic CMP descriptor?

Hey all...

I have been tasked with moving from an Oracle database to a MySQL database, running under BEA Weblogic Server 9.2. We have a bunch of EJB 2.1's that need to be ported.

The problem is, Weblogic seems to not know how to map Blobs and Clobs to MySQL, but only to Oracle and DB2. Specifying MySQL as the database-type in the CMP entity bean descriptor returns an error from the EJB compiler to that effect.

Has anyone successfully been able to move from Oracle to MySQL, using Weblogic, and EJB 2.1's using container-managed persistence? This is driving me nuts, as there seems to be very little info on this (and very few people who use this combination).
