Chapter 3: Façade Pattern
In this chapter we introduce the intent of the façade pattern with a brief discussion of the benefits that the implementation of this pattern brings.
We continue by discussing three ways that the pattern can be implemented: POJO, stateless and stateful session bean façade and the important differences between the stateful and stateless session bean façade.
The chapter ends with a discussion of when and where to use this pattern and warnings about its use and potential pit-falls.
