In this chapter, we have re-built the application that we developed in the last three chapters, but this time in a proper, scalable structure using separate workspaces for separate parts of the application. Based on ADF libraries built on the three foundation workspaces, we have developed two separate subsystems and deployed these as ADF libraries as well.
Finally, we built a master application putting these libraries together to a finished application. In this way, you can build any size of system by splitting it up in various task flows and subsystems.
If you followed along in JDeveloper while reading this chapter, you will probably have experienced a thing or two that did not work the first time. To find errors, logging and debugging is an important part of application development. That is the topic of Chapter 6 , Debugging ADF Applications.
