Again, as we've asked you numerous times, SPELL OUT YOUR WORDS
. And there's no way we can answer your question, since you provide no useful details. All you've told us is you've got some 'java application' that's now getting a network error.
Diagnose the problem as you would with ANY network issue. Try to ping the remote server. If you can't, then check your routers/switches/etc., until you CAN get a route to the server. If the remote server is yours, check the service(s) on it. If this WAS working, and now it ISN'T, then (quite obviously), SOMETHING changed.
