JBoss 3.0 Reduces Development Time and Cost
Dain Sundstrom, IBM

Track: Java
Date: Friday, July 26
Time: 1:45pm - 2:30pm
Location: Marina III

JBoss has always been focused on making J2EE development painless and efficient. The most recent JBoss release, JBoss 3.0, includes several features that highlight how the efficiencies of J2EE (including a decrease in coding time, testing time and administration) can be fully realized. Certain core JBoss features will be discussed in detail with regard to providing an example of how to develop with these efficiencies in mind.

  • CMP 2.0:
    The introduction of CMP 2.0 has expanded the original CMP specification and provides for a highly functional, developer-friendly, feature rich environment. CMP 2.0 includes container-managed relationships, an EJB focused query language, and many performance enhancements.
  • Clustering:
    Clustering in JBoss is simple to configure and use, and allows for the deployment of large applications across many inexpensive servers.
  • Hot-deployable services:
    JBoss has always had the ability to add, remove, and redeploy J2EE applications without restarting the server. In 3.0 this has been expanded to services such as database drivers, message queues, clustering, and even EJB itself.
  • JMX:
    JMX is designed to enable the efficient management of server components. However, it really shines as a tool for debugging running servers. JMX is built into the JBoss micro kernel, and by using one of the JMX connectors, a developer or sysadmin can adjust the properties of any running service.
