UML 2.0 to XMI MOF

Using Poseidon tool, I have design a metamodel based on UML2.0. Later, using the same tool have imported it to XMI (1.2).

Then I tried to transform this XMI file to XMI MOF as I tend to use output for further processing.

I tried JunoMda a online transformation servlet, but failed (due to the JunoMda server problem).

Is there any other tool that can be suggested?? thank you.
