Applet and JMS

Hi All,
I am rather new to the JMS technology and know only the basics as of now. I was wondering whether it is a problem to incorporate Applets to receive messages from the application server using the pub/sub model, and to display the message or not?
I have an applet in my JSP page and I want to display the message that it receives from an EJB (using JMS). How & where is the JNDI naming lookup handled?
I would be grateful if somebody could help me out and also tell me how the above may be achieved (basic architecture).
Regards, Sanjit
