Hi all Is localhost always = 127.0.0.1 for Tomcat 4.0? I did check it on 5 machines. http://localhost:8080 always brings me "An error has occurred processing the request... Unable to contact site SERVER Press 'Refresh' on your browser to try again." http://127.0.0.1:8080 is OK.
You Don't want to remap localhost. This is a "magic" IP address and I don't know what would break but certainly wouldn't care to find out. On my Linux system, the OS install created a line in the /etc/hosts file tagged with the comment that removing the localhost definition would "cause various programs that require network funcitonality to fail". The Windows equivalent to /etc/hosts is %WINDOWS%\LMHOSTS, but that file is not present by default, so I suspect that the definition for localhost is either hard-coded in the OS or hidden in some sneaky part of the Registry. There are some OS's where localhost ISN'T defined by default - I believe I've read of Solaris being noted for that. However, it is ALWAYS defined for any Windows 9x/NT (or successor) networked machine. If you really want to write something tied to your specific machine (as opposed to whatever machine you're running the software on) refer to it by its hostname - which is the machine ID it was given by the LAN administrator (visible in Network Neighborhood/Properties, aka "My Network Places/Properties"). If you enter "http://localhost" or "http://127.0.0.1" in your browser, it will look for a web server running at TCP/IP port 80 on your computer. If you want to access that server from another computer in your LAN and the machine ID is "FRED123", then say "http://FRED123". Under Linux, IP 127.0.0.1 isn't attached to a physical network device - it uses a special device called the "loopback" device. Windows may be doing something similar for performance reasons.
