Thanks for the link. I have followed the instruction given in the link. However, it does not work. It still shows the error message "*** Socket error: Port 0 is already in use. ***". I have also tried to start the second JBoss instance with -b option (different IP address on the same NIC). But still it gives the same error. I am wondering what could be the reason for that error ?
