I installed Tomcat for the first time. When I start it, it hangs?

I try to start Tomcat and an extra window appears with no errors. The
extra window, I have also ran it in the same window to check for
errors, gets to the line:

INFO: Server startup in xxxx ms

Then it does nothing. It just hangs?

Since I am a newbie, this has to be something simple. Any help would
greatly be appreciated.

Thanks,

Gary
