YUI plugin -please suggest me how to imlementing it

[Varun Deep]

Hello to all
 
I am using the YUI plugin with my struts2 based application. I
downloaded jsonplugin-0.30.jar put it in the lib directory.
I have also done the required coding for it. But still I am not able to
load the required class file.
Please suggest me the steps required to implement it.
 
Thanks in advance
