Download and install Sun Java SE JDK 6 Update 21 or later. At this time these are the only versions of any JDK supported with OpenIG.

Download and install Tomcat 6 or Tomcat 7.

`$TOMCAT_HOME` refers to the location where you have installed Tomcat.

Configure Tomcat to listen on the same port and protocol of the application you are protecting with OpenIG. If your application listens on both an HTTP and an HTTPS port you must configure Tomcat to do so as well. If you are installing to run the samples you do not have to modify the Tomcat port configuration since both the Tomcat default and the samples use port 8080.

To configure Tomcat to use a port other than 8080 modify the defaults in `$TOMCAT_HOME/conf/server.xml`. The quickest way to do this is to search for the default value of 8080 and replace it with the new port number.
