When you need greater processing power beyond what basic HTML and scripting has to offer, NetWare offers two choices: Tomcat and Novell exteNd™ Application Server.The one you choose depends on what you need.
For example, if you need Java API support beyond servlets, JSPs, tag libraries, or basic JavaBeans* components, either immediately or in the future, you should select the Novell exteNd Application Server. Also, if you are going to use any of the high-end development tools included with NetWare, such as exteNd Director™ and exteNd Composer™, exteNd is the better choice because Tomcat is not supported by these tools. (For more information about Novell exteNd, see the exteNd documentation.)
However, if you need only very basic Java servlets and JSPs and you do not plan to migrate to a more robust solution, you should select Tomcat. Tomcat is also the better choice if you are not experienced with Java programming.
