Hi, Im migrating an ALBPM 6.5 running on a WLS 10.0 to an Oracle BPM 10.3.1 running on WLS 10.3.1

I got some problems with the Oracle driver because the old driver (weblogic.jdbcx.oracle.OracleDataSource) was definitely removed from the server and is not longer supported. Instead I used the thin driver (oracle.jdbc.xa.OracleXADataSource), the database migration was executed succesfully but after that, when I try to deploy the engine ear in WebLogic I got exceptions asociated to the driver:

[     (cont)     ] Main: Caused by: weblogic.application.ModuleException: [HTTP:101216]Servlet: "engineStartup" failed to preload on startup in Web application: "/albpmServices/albpm_engine".

I was looking around for a solution but all is pointing to use the old driver, I think isn't a good practice to force the server to use this driver after Oracle remove it completely. Any suggestions or similar experiences??
