[jboss-user] [Beginners Corner] - Re: Naming Service Error(could not start on port 1099)

[PeterJ]

Some possibilities:

1) Port 1099 is in use but tcpview is not showing it (there was a while on XP where tcpview did not show all opened ports - a later XP patch fixed this). Try using netstat, see if that helps. Oh, another way to tell of a port is open it to use telnet to test it:

telnet localhost 1099

If the port is not open, you will get a connection error. If the port is open, you will see text+gibberish, and possibly a screen refresh (like using the 'cls' command)

2) You have a firewall and it is preventing the port from being opened.

3) The JVM is unable to open the port for some reason. JDK 1.3.1_01 is a very old version of 1.3.1, perhaps you should try using the latest patch for 1.3.1. (Looks like 1.3.1_19 is the latest for Windows)
