Yes, you need to have the jar file to get all the class files needed.
Make sure the jar file can be found by the web browser -- that is a
problem I have sometimes had.

(this HTML snippet was copied from the Jython demo applets on
jython.sourceforge.net/applets/index.html)

<APPLET CODE="HelloWorld" WIDTH="160" HEIGHT="50"
    ARCHIVE="appletdemo.jar" 
    NAME="HelloWorld"
    ALIGN="BOTTOM" 
    alt="This browser doesn't support JDK 1.1 applets.">

In the <APPLET> tag the CODE and ARCHIVE are the most important
arguments.  The ARCHIVE must specifiy the path to the jar file.  The
CODE argument specifies the fully qualified Java name of your "main"
class (include packages separated by a '.').

With Netscape 6 on Windows 2000 there is the "Java console" which is
really helpful for displaying error messages (such as the JVM not
being able to find the jar/class) and (Java) stack traces.  You can
see this console if you right-click on the Duke guy in the System Tray
and selecting "Show Console".
