Isn't there an FAQ on this?

1) Make sure another copy of Tomcat isn't already running.
  (We've all accidentally tried running two copies of Tomcat before.)

   ps -ef | grep java       (SysV)
   ps -auxww | grep java    (BSD)

2) Use
      netstat -a
   to see which ports are open by other programs.  In the default
   installation, Tomcat tries to open ports 8080 (listens for HTTP
   requests) and 8007 (listens for AJP requests from Apache).
   If another program is using one of those, Tomcat will not start.

   Using additional netstat options in conjunction with fstat,
   it should be possible to track down which program is using those
   other ports, but that's a rather tedious process.
