JBoss is an Open Source, standard compliant, Enterprise JavaBeans Application
Server implemented in 100% Pure Java. It is usable for both development and
production. JBoss is licensed under the LGPL. Which means that you are entitled to redistribute the jboss binary (the jar) free of charge without modifications. You can distribute your code under any license you wish. JBoss 2 is designed to be an EJB v1.1 container and server. Some parts of EJB 2.0 are supported in the 2.4.x versions, for example Message Driven Beans. JBoss 3.x supports EJB v2.0 including Container Managed Persistence. JBoss comes bundled with Jakarta Tomcat or Jetty to serve web pages, JSP pages and Servlets. JBoss can be run on different machines. There is no requirement for root access to run JBoss as none of the default ports are below the 1024 priveledged port range. JBoss will run very effectively on a machine with 64 megabytes of RAM, and requires only a few megabytes of disk (including source code!). One of the nicest features of JBoss is its support for "hot" deployment. What this means is that deploying a Bean is a simple as copying its JAR file into the deployment directory. If this is done while the Bean is already loaded, JBoss automatically unloads it, then loads the new version. There is a built-in SQL database server for handling persistent beans, and this starts up automatically with the server.
