implementing Space based on JDBC

Hi

I want to implement store and forward module. Our Architecture is a
SAF  module that it closely work with Oracle Database.So I decided to
search the group and I have been informed about  a class in JPOS-EE
(org.jpos.saf.SAF() ), but this class uses JDBMSpace as a persistence
layer. So my Questions:
1- Is there any space implementation based on JDBC?
2- If not What Can I do? Can I convert JDBMSpace to JDBCSpace.

Best Regards.
