This section explores using Java to consume the ABAP web service created in Chapter 15.
Service consumers can be created in a variety of ways and visualized using Web Dynpro, JSPs, or ASPs, for example. In this section, we'll create a UI using Web Dynpro for Java. As mentioned earlier, Web Dynpro for Java is integrated into SAP NetWeaver Developer Studio as an Eclipse perspective.
