Interfaces and Implementations not in the same JAR

Hi,
We are using the version 2.0.0-SNAPSHOT of ejb3unit and we are still experimenting problems when the Interfaces (Remote or Local) and the Bean Implementation are not in the same JAR.
The Error Messages are:
No class was found for interface...
More than 1 itf on class...

When will this feature be implemented? Without it we can not use ejb3unit.
Thank You for Your Help
