Hi. I'm having some problems when generating an application with SeamGen 2.1.1.GA. I can create the application and it works well, no problem. But the console shows me an error message every time I do any action in the application.

The error message:

ERROR [[default]] Servlet.service() for servlet default threw exception
java.lang.NoClassDefFoundError: Could not initialize class sun.awt.Win32GraphicsEnvironment

Does any body know what is this? I've already worked with this kind of application and have never had problems.
