POJO (Plain Old Java Objects) is a term that has been tossed about a lot lately, referring to code written as plain Java classes.

Secondly, the SCA programming model is a POJO programming model, it's based on annotations, XML configurations, and dependency injection.

The methods on a Service POJO are one-to-one with the Session Bean facade.

This gets around having to build POJO to SDO converters, since at the current time SCA only uses SDO for data types.

This method is generated for each reference defined by a POJO component.

The result is a simple POJO, as shown in Figure 29.

If not, I need to know how a Task POJO will access "sub" services in its method implementations.
