[SOLVED] ClassNotFoundException Error

[dan0]

When I try to run my applet in a Firefox or IE browser I get the error below, anyone know how to resolve this?

load: class TestAppletGUI not found.

There are two classes TestAppletGUI and AppletGUI, which are in a named package - projects.web - both of these classes are archived in UserInterface.jar

In my web-page I use an applet tag:

<applet code="TestAppletGUI" archive="UserInterface.jar" width="500" height="500">
</applet>

I got the applet to run by:

1. Changing the code reference to: projects.web.TestAppletGUI (the FQCN)
2. re-archiving the class files

To create the jar file I used the following cmd:

jar cvf UserInterface.jar projects\web\AppletGUI.class projects\web\TestAppletGUI.class
