Oracle Forms

Hi,

I am testing our system on App Server 10g Rel2 trying to create a form with a graph and using the Formsgraph.jar bean.

I have done this a couple of years ago on a separate project with no problem.

This time it is not working, and I am getting this error in the java console log, and advice would be welcome:

java.lang.UnsupportedClassVersionError: oracle/forms/demos/bigraph/FormsGraph (Unsupported major.minor version 50.0)
