I run shutdown.bat first but didnt work then i even restarted my system but still had problem then I closed process of my messenger and it worked. Sometimes it happens that messenger insalled in your system using port so you get conflicts while running jboss So close them and restart jboss server. But i would like to know if anyone can tell how manualy we can change and set ports and assign Jboss server a fixed port to use?
