Error while starting Tomcat. First time using Tomcat.

[bryanbennett]

I am very new to Tomcat. This is my first day using it. I tried to start Tomcat and this error message popped up.

Bellow is the command line and below that is the Error:

C:\Program Files\Apache Group\Tomcat 4.1\bin>startup.bat
The JAVA_HOME environment variable is not defined
This environment variable is needed to run this program
Using CATALINA_BASE: ..
Using CATALINA_HOME: ..
Using CATALINA_TMPDIR: ..\temp
Using JAVA_HOME:
The system cannot find the file -Dsun.io.useCanonCaches=false.
C:\Program Files\Apache Group\Tomcat 4.1\bin>

the Error is:
Windows cannot find '-Dsun.io.useCanonCaches=false'

Nope - the first error is quote self explanatory :

The JAVA_HOME environment variable is not defined
This environment variable is needed to run this program

You need to add an environment variable called JAVA_HOME, which should point to your installed JDK.

thank you for this great advice.

When I press Start/control panel/system/advanced/environment variables I don't see a variable that says JAVA_HOME.

1) Should I add that variable name?
2) Then where should the path of that variable point to?
