Starting up Tomcat using "$CATALINA_HOME\bin\startup.bat" command

Question

Hello,

Trying to get an working environment for Struts 2, I'm trying to do things as suggested by this tutorial.

1. I've downloaded Eclipse Helios Which, I heard, comes whith JDK 1.6.
2. I've downloaded Tomcat 7.00-preconfigured.

I'm told to (1) Unzip the Tomcat files, then (2) start Tomcat by executing the "$CATALINA_HOME\bin\startup.bat", and (3) check to state of the installation by typing localhost:8080 to see.

So,

1. I went to the bin directory and r-click on the Cataline Windows Bat file, but I get 404 file not found when I type localhost:8080 on my browser.1.
2. I've tried also to run "Startup" file, but with no more success.

So, what's that CATALINA think? I've been on it for over 3 days now. I'm trying to write a basic "Hello World" in STRUTS.

Thanks for Helping
