Install an application server
Depending on your requirements you may choose to install either Tomcat or JBoss - both of them are Java servlet application servers. Tomcat is lightweight and less complex to setup and use. JBoss, on the other hand, provides a full Java Enterprise Edition (JEE) stack and other technologies that are useful when working with enterprise Java applications.
We recommend that you install and use Tomcat. That’s because our applications don’t use the full range of JEE features, and choosing JBoss will just add a lot of complexity to deployment and resource overhead that will go unused. For example, the JBoss installation files are around an order of magnitude larger than Tomcat’s.
Our applications have been tested and verified to work with both application servers. Note, that it possible to have both Tomcat and JBoss installed on the same system.
