Hello Ulf, thank you for your reply.
I changed the codebase attribute as follows:
<jsp:plugin type="applet" code="GraphApplet" codebase="" jreversion="1.6" width="400" height="300" >
Because Eclipse indicated that codebase was a required attribute, I changed the value to "" instead of removing the attribute. This resulted in a new (slightly confusing) error. There is still a class not found exception but it is accompanied by a number of errors related to applets and graphics and the likes. Should I assume that my applet is causing this and continue my debugging there?

This line "Caused by: java.io.IOException: open HTTP connection failed:http://localhost:8080/GraphApplet.class" also strikes me as strange, why is the page looking for the class there? The url to the page that the applet is on is "http://localhost:8080/EPSTestWeb/ResultServlet".
Any suggestions?
