<div>I have created proxy only on  server  grid02. So, server 02 delegates proxy to server grid03 ans server grid03 in turn delegates proxy to grid04 .<div><div><br></div><div>But when I run this Main program, job  is submitted properly. But next server grid03 fails to submit a job on server grid04. It gives me following exception.</div>
