Does any one know how can i fix it ?
You can try to download the JNLP file localy and starts it using a command : javaws file.jnlp you will have more informations about the potential errors.
JNLP is a little annoying initially if you don't get it right. I had the same experience, follow this tutorial, it works like a charm.
Also, please post some error/warning message. Your question is very broad.
