Summary


This marks the end of the business logic development on our example application, Plants-By-WebSphere. In this chapter, we started with the presentation logic we created in Chapter 4. We discussed briefly how component-based application development is a useful organizational model for separating presentation, business, and data logic, and how the EJB component model is especially well suited to the task of implementing business abstractions from that model.

We then focused on the model side of the Plants-By-WebSphere model-view-controller design, walking through the development of several principle EJBs that compose the implementation, step-by-step, including connecting the EJBs back into the presentation logic's model abstract layer.

Hopefully, this chapter has rounded out your picture of one way to partition and implement a common type of Internet application, and more specifically, how to apply WebSphere technology to that job. In the next chapter we'll take the next step in J2EE application development, by exploring the Assembly role and the WebSphere tools that support that task. We will also show you how to configure the WebSphere Studio test environment and take our nascent Plants-By-WebSphere application, now including both presentation and business logic, on a test drive.
