how to use dwr with jsf and netbeans 6

Hello friends..
I am developing a small community site application. I am using jsf technology in netbeans 6 ide. I was supposed to use dwr (comet) to give ajax functionality to my pages. I tried it with ordinary jsp pages in eclipse. And it was success. But when it came to the JSF field, none was working. I think the system has not identified dwr.xml. because, it shows an error , It couldn�t find dwr/util.js itself. I have done all the necessary steps, like in dwr.xml I gave creator as jsf and edited all configuration files. But not use. My cant resume my project without adding ajax functionality.
If anybody has succeeded in implementing dwr 2 perfectly with jsf, please give me a detailed information, so that I can check whether I maid any mistakes. Please help me
Thanks
