I've tiny bit confusion regarding apache tomcat installation.

So, I must realize that what is the main difference between your .zip and also the .exe tomcat ?

Thanks ahead of time...

The exe will install Tomcat like a Home windows Service. The zip file will help you to stop and start Tomcat using batch files in order to by hand install the service. If you wish to integrate Tomcat by having an IDE, you'll need the zip file, because the needed batch files aren't incorporated within the exe version.
