Error shows that you dont have configure Tomcat properly in your machine . Try to reinstall or give me more error logs so that I can able to help you further.
how do you stat the tomcat, do you use startup.bat file?If you use the Windows Task Manager, can you see Tomcat as a running process?
well,if you are still not able to find any solution doing all this.please reinstall Tomcat
Sometimes a re installation is the best thing to do any way. I find sometimes when i search too long for a problem I only get a few attempts to fix it. By the 4th or 5th thing I try I find I am only making things worse!
