JasperReports Server requires an application server in order to run. The installer is pre-configured to run with the Apache Tomcat server. When you run the installer, two options appear on Setup — Please select the Tomcat configuration you want to use:

If you choose this option, the installer puts an instance of Tomcat 6 onto your system. Later, after choosing a bundled or existing database, you are prompted for the server port and shutdown port that Tomcat will use. Most users accept the default values that are displayed. Accept the default values or enter alternate values, then click Next.

If you already have an instance of Tomcat on your system, you can choose this option. Later, after choosing a bundled or existing database, you are prompted for the location of Tomcat. You can browse to the folder where you installed Tomcat, such as C:Apache Software FoundationTomcat 7.

After selecting a PostgreSQL configuration, you are prompted for Tomcat's server port and shutdown port. Accept the default values, 8080 and 8005 by default, or enter alternate values.
