Unzip the file into a directory and set an environment variable TOMCAT_HOME to your main Tomcat directory:

For example,
 
set TOMCAT_HOME=c:\tomcat

To start the server change to the tomcat\bin directory and type:

Open a web browser and in the address box type:

http://localhost:8080/  - this displays the example page.
