Business Objects (EJB Components)

These are general Java classes used to transport information between the different layers. Instead of beans being sent across the layers to the view end, the retrieved information is packaged into respective business objects and placed in MVCAppValueObjects. Listings C.34 C.38 are the detailed listings for each of the business objects. These files are to be placed in the directory called ejb_components_src, discussed on Day 16, and the deployable is to be put in the classpath where the Web components are compiled.
