Running Java GUI apps on Cloud 9

问题

I'm trying to run a simple app that just creates a JFrame and displays it through the web IDE Cloud 9. I'm getting two separate errors

1. Exception in thread "main" java.awt.HeadlessException:
   No X11 DISPLAY variable was set, but this program performed an operation which requires it.

   When this issue is resolved here I then get this error:

2. Exception in thread "main" java.lang.UnsupportedClassVersionError:

Is it possible to run GUI programs through cloud 9? Does anyone know how to update the path variable/java version on cloud 9?

回答1:

It is not possible to run GUI programs on Cloud9.
