I've created a JNLP file and placed in the server.It's working fine now.
My idea is - If someone was accessing the jnlp file from some locations,i cannot update the supported jar files..
In that case, how will one update the jar files... ?
Thanks Thompson for your comment.
One can update the jar file on server irrespective if some-one was using your jnlp file or not..
Once you're uploaded the new jar file, the users who were accessing jnlp file will get updated immediately,when the jnlp file is started in their machine.
