The WebLogic Server did not start up properly.
Exception raised: 'weblogic.server.ServerLifecycleException: Server failed to bind to the requested port. See preceeding log message for details.'
Reason: Server failed to bind to the requested port. See preceeding log message for details.
Why it is saying this how will the change the port if already 7001 is used ?
Thanks,

Hi,
You're running startWebLogic.sh, so I'm assuming this is on a *nix platform.  Assuming that's the case, reboot your system (to make sure you have a clean start), then try running:
netstat -an|grep 7001
to see if there is something actually listening on port 7001.
If you do find something that is already listening on port 7001, try doing:
ps -ef | more
and review the output from that, to see if you can try to figure out what might be listening on port 7001.
