problem with java swing

Currently, I am using Java AWT package as well as JRadioButton(I am only using one J command the rest is using AWT) for my project.

As the project is a web base project, I am trying to load the project into the web using JRun, but failed. There is an error, error as follow:
exception: java.lang.ClassNotFound Exception javax.swing.JRadioButton.

Can anyone please advise.
Thanks

In order to use swing components in web browsers you need to A) Install the Java Plug-in (which is just the JRE) and B)convert your html file using the HTML Conversion program supplied by Sun. The browsers run of JRE1.1.x, and thus don't know how to deal with swing since swing was only full introduced in jdk1.2.
