Not able to start Tomcat

[Babu parigi]

Hi All,
GM/GE, this my first post in the forum .
I am using windows 7 lappy, it came with java 7 installed by default.
I installed jdk 1.6 and given JAVA_HOME environment variable as C:\Program Files (x86)\Java\jdk1.6.0_17.
I downloaded apache-tomcat-6.0.35-src and unzipped it , when I start the server by clicking on startup.bat, a small window opens and closes in fraction of seconds.Am not able to see whats happening in that window. when I ran from command prompt I will get the below error,

F:\Babu\apache-tomcat-6.0.35-src\apache-tomcat-6.0.35-src\bin>startup.bat
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
F:\Babu\apache-tomcat-6.0.35-src\apache-tomcat-6.0.35-src\bin>

Here, I am not able to understand why am I getting this error though I defined the environment variable.
Also, am not able to see the log folder which holds the catalina log in my tomcat extraction.

I will be very much thankful for any suggestions and/or solutions ....

Thanks,

Babu

If startup.bat says

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

then something is wrong with your environment. Open a command prompt window and type SET to double check - recall that Java cares about case.
