Most common cause of the problem: JAVA_HOME environment variable not set, or set incorrectly.
It should point to your java directory: ie C:\java1_4\ NOT C:\java1_4\bin
Another possible cause is spaces in the path names where you have installed applications.
Check out this page: http://www.coreservlets.com/Apache-Tomcat-Tutorial/ for a tutorial on installing tomcat.
If you can't sort it out on your own, we need more info:
Where have you installed Java?
Where have installed Tomcat?
What is the value of JAVA_HOME environment variable?
Good luck,
