ClassCastException in Eclipse 3.0M

[Joel]

I am unable to open XSD files in Eclipse 3.0.M6 and 3.0M7. The stacktrace of the logs is below. Am I missing a dependent plugin? Thanks.

Hi Joel,

Please make sure you open the schema with oXygen, select Open With -> Oxygen XSD Editor from the contextual menu (right click in Windows).

Best Regards,
George
