Import Java's Swing classes/packages into Visual J++??

Hi,
I am trying to get the answer to a question that has been touched on a few times in this board.

I have just downloaded the Java SDK 1.2.2 and want to use my Visual J++ 6.0 edition as the IDE.
Unfortunately, it will not compile due to being unable to find the swing packages in my file. Does anyone know how to include the necessary swing files into my project. It complains over:
javax.swing..etc

There are option settings under the Project properties classpath box to include/extend the classpath but don't know what to extend it to.

If anyone knows how to do this would be really grateful for any detailed help. I would not be deploying my projects - this is just for home use.

thanks,
mark
