Installing and running an application server
If you wish to use the Grouper user interface (UI) you will need to install an application server in which to run it. The application server must support the Java Servlet specification version 2.?, of which there is a wide choice, including:
Apache Tomcat
Jetty
IBM Websphere
Oracle app server
Oracle Glassfish
Grouper does not require any of the services provided by a JEE server beyond those required by the Servlet specification, so it would not be worth procuring an expensive commercial server for this reason. The majority of Grouper UI installation are running on Tomcat, so we will concentrate on this server.

We covered these procedures in the quick start section. Stop before setting up the web application.
