JSR-227 Standard Data Binding

Increasingly, enterprise applications model persistent datasources as Java classes and develop Business Services that query, manipulate, and persist these objects. However, developing interactive user interfaces that use Business Services to correctly manipulate the data objects requires understanding and coding against complex sets of design patterns and standards that underly the various Service technologies. This proposed specification will define a framework of classes, called Declarative Bindings, that formalize the characteristic interactions between typical UI components and values and methods available on Business Services.

By using the Declarative Bindings set forth in this specificiation, any Java UI rendering technology can declaratively bind to any Business Service. Example UI components and controller technologies include: JSP JSTL tags, JSF, Struts, and Swing. Example business services include SOAP Web Services, EJB Session Beans or any Java class being used as an interface to some functionality.
