This section presents a step-by-step tutorial on how to set up 'JBoss', the free Enterprise JavaBean (EJB) server, and create

It doesn't explain what Enterprise JavaBeans are, or how they are used; there are a number of good introductory articles on Sun's JavaSoft Web site. Although the description is based on the use of a Linux server, most of the issues discussed in this article will also apply to other platforms. If you are using a Windows platform you will need to pay attention to the directory names, which will be different from the one's I've assumed. JBoss is an implementation of the EJB 1.1 (and parts of 2.0) specification, that is, it is a server and container for Enterprise JavaBeans.


In this it is similar to Sun's 'J2SDK Enterprise Edition' (J2EE), but the JBoss core server provides only an EJB server. The JBoss core does not include a web container for servlets/JSP pages, although there are bundles available that include either Tomcat or Jetty. The minimal core offering means that JBoss has minimal memory and disk space requirements. JBoss will run very effectively on a machine with 64 megabytes of RAM, and requires only a few megabytes of disk (including source code!). Sun's J2EE requires a minimum of 128 megabytes of RAM, and 31 megabytes of disk space. Because of its small memory footprint, JBoss starts up about 10 times faster than J2EE.
