If you installed webMathematica as described above, you should be able to connect to this JSP via http://localhost:8080/webMathematica/Examples/Plot3DLive.jsp. (You may have some other URL for accessing your server.) It allows the user to enter a function to be plotted by the LiveGraphics3D applet. The source for this page is in webMathematica/Examples/Plot3DLive.jsp.

This example uses a number of evaluations to set up parameters. The last evaluation takes the values of these parameters and uses them in a call to Plot3D. The result of this goes to MSPLive3D, which calls the LiveGraphics3D applet. This gives a real-time rotation of the three-dimensional graphics object.
