Gerald Löffler is a Java Architect with the Sun Java Center, Sun Microsystems' Java consulting division, and provides consulting services in the area of OOA&D, software architecture and Java implementation, with a focus on enterprise software systems and J2EE. He holds a PhD in Bioinformatics.

Message Driven Beans (MDBs) bring together asynchronous messaging and the enterprise component architecture of EJBs. After a very brief introduction to the Java Messaging Service (JMS) and the nature of MDBs, we present some scenarios from recent projects in which MDBs have proven useful. Familiarity with the fundamentals of J2EE and EJBs is assumed in this talk.
