Hi..
we have an Application in that we are using NIoserver for Incoming Requests from then i am listening the remote
JBOSS JMS-Topic.its working fine
up to now.but it not working now.one thing we done is we changed the systems.
here my Question is what are the Ports that i should have permission for Lookup.
when i am doing lookup it not giving any error or Exception.simply the program is in Stop (Blocked). i don't know why this will happen??
can you give me any solution about this?
after a long time i got this Exception........
