An Enterprise Service Bus (ESB) brings flow-related functionality such as message routing and transformation to a Service-Oriented Architecture. An ESB also provides a layer of abstraction with endpoints for various protocols and transports. These features promote decoupling of integration logic from business functions, flexibility in the transport layer, and pluggability of POJO services.

While ESB is a vast topic, this session will offer a glimpse of a few technologies (scheduling, messaging, and remoting) within the context of an ESB. The content will be heavily example-based with a good deal of code and configuration. The emphasis will be on Spring's enabling role for implementing POJO-based solutions that achieve flexibility in the face of the constantly changing requirements of enterprise integration.
