Most likely you are not using IPv6, but if you are, you also need this line: ::1 localhost If you have any other line, such as this: 192.168.0.100 somehostname where 'somehostname' is your PC's host name, make sure that the IP address is correct. I also asked about CPU utilization - is that info also confidential? anonymous wrote : Why is it not successfully running in other system.?[/quoute] | | I have no idea. I have run JBoss AS, from version 3.2.3 up through 5.1.0, on dozens of Windows and Linux machines without errors. And all I did was unzipped the download and ran it. Also, it looks like the error output scrolled off of the command prompt buffer - I suggest increasing the buffer size (mine is at 9000) or redirecting stdout to a file. You really need to catch the first error - it is the only interesting one. | | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246750#...
