Hi David, You can use Filtering Classloader that weblogic server supports.

Apparently WebLogic 10 already includes a version of OpenJPA, but certainly an older version. Will I have any trouble using the latest OpenJPA just in my webapp? Is there something I need to do to prevent conflicts? I'm familiar with "prefer-web-inf-classes", but I'm not sure whether that will help.
