How to pass a class from Jdev.class diagram to VPUML class diagram

I’ve the SDE-Jdeveloper 2.1 modeler edition.
I need to use the class diagram, part of the Jdeveloper diagrams and also the VP-UML class diagram.
I’m in trouble because I can’t copy nor import classes from one diagram to the other.
Is there any simple way to do it?

Dear hein,

There is no simple method to transfer JDeveloper diagrams to SDE or VP-UML. If JDeveloper does provide export of UML model to XMI, you can try exporting the model from it and then import the XMI to SDE or VP-UML.
