Since these exporters and client side endpoint accessors are defined using meta data for Spring IoC container, you can easily use dependency injection on them to set initial state and to 'wire up' the presentation tier, such as web forms, to the service layer. In addition, you may apply AOP aspects to the exported classes and/or service endpoints to apply behavior such as logging, security, or other custom behavior that may not be provided by the target distributed technology. The Spring specific terminology for this approach to object distribution is known as Portable Service Abstractions (PSA). As a result of this approach, you can decide much later in the development process the technical details of how you will distribute your objects as compared to traditional code centric approaches. Changing of the implementation is done though configuration of the IoC container and not by recompilation. Of course, you may choose to not use the IoC container to manage these objects and use the exporter and service endpoints programatically.
