Get screen size in Google App Engine

In a servlet I'm running on GAE, I'm trying to get the screen width in pixels of the device being used so that I can dynamically redirect the user to either the desktop or mobile jsp page. I first tried using the java.awt.Toolkit.getDefaultToolkit().getScreenSize() but receieved the error message: java.awt.Toolkit is not supported by Google App Engine's Java runtime environment. For now, I'm running the screen check in a jsp page using javascript but I'd like to move it to the servlets.

You can't move it to the servlets. The server is not aware of the user's screen or any details besides user-agent and what Javascript provides. You'll need to use Javascript and pass around the screen size in a cookie or in the requests.

java.awt.Toolkit.getDefaultToolkit().getScreenSize()

being run on GAE is not applicable as we don't care about GAE's screen which is nonexistent anyway.
