problem with path and classpath

Hi all,
 
I am not sure whether this is the place to post my queries to, but anybody please let me know if there is any other place where I can go for help.
 
I have written a chat application using openjms. It works fine if I run it from prompt mode but it gives the following error if I try to run the application through an applet. I am not sure if it has something to do with the browser.
 
The error is:
java.lang.NoClassDefFoundError: javax/jms/MessageListener
 at chattest.init(chattest.java:16)
 at sun.applet.AppletPanel.run(AppletPanel.java:348)
 at java.lang.Thread.run(Thread.java:536)
 
But I have set the path and class path of openjms library properly both in autoexec.bat and the system's envornmental variables.
 
Could anybody please help?
 
Thanks for any help in advance.
 
-Vidya.
