TOMCAT_HOME and JAVA_HOME

Hello,
I got a problem to define JAVA_HOME and TOMCAT_HOME environment variables. I am using Windows Vista. I downloaded Tomcat5.0.28, j2sdk1.4.2_17 and jdk1.5.0_12. I added jdk1.5.0_12 and j2sdk1.4.2_17 in PATH, but I do not know how to do the others. Could you please give me some advice and send me color pictures to show me how to define the environment variables?
I am able to run Tomcat. The
http://localhost:8080/ comes out correctly. However, after I type "cmd" from the start menu, in the directory C:\> I type: cd Tomcat5.0.28 it says "no such directory". I do not know what is wrong. I put Tomcat5.0.28 under C and I can see Tomcat5.0.28 icon on my desktop. "java -version" shows that j2sdk is installed correctly. I think there is problem with TOMCAT_HOME. Should I define CATALINA_HOME, too?
Could you please help me? Could you please email me about this problem?

Thank you very much for your time in advance.

Best wishes,
Sunny

I am able to run Tomcat.

just navigate to
tomcat related settings

However, after I type "cmd" from the start menu, in the directory C:\> I type: cd Tomcat5.0.28 it says "no such directory". I do not know what is wrong.

why shouldn't this error be thrown?
I could guess your tomcat installation directory is C:\program files\Tomcat5.0.28.

Hello Santomh,
