System Presentation

XMLbroker is the prototype of a middleware framework--based on the RPC paradigm--aimed at the integration of software over the Internet. We refer to this concept as Web integration because further than embracing the Internet as a transport media, XMLbroker adheres to technology standards defined by the World Wide Web Consortium (W3C). Namely HTTP 1.1, and SOAP 1.1.
XMLbroker builds upon the server-side Java software infrastructure (Java 2 Enterprise Edition, or J2EE), exposing Enterprise Java Beans (EJB) components as Web services. The software is composed of two entities:

1. a server built as an extension module to the JBoss application server (e.g. running in the same process)
2. a client, implementing the transparency layers between the host application and the server

The reasons that led to the choice of the Java platform will be discussed in Chapter 3.
