how to ship jar with applet

I have a problem in shipping jar files with applet.

I have a applet which does xml parsing using

org.w3c.dom.Document;

org.w3c.dom.Element;

javax.xml.parsers.DocumentBuilderFactory;

javax.xml.parsers.DocumentBuilder;

files.

For JRE 1.5,1.4 has the above files by default. But for lower versions iam planning to ship server.jar.

How can i ship both my app.jar and server.jar so that my applet runs in 1.3,1.2 without any user invervention.

Thanks in advance.
