4.8. Summary

In this chapter, we discussed how to code, compile, assemble, deploy, and test the simplest of simple EJBs. We saw how the methods in the home interface and remote interface were realized in the EJB implementation class, and how and when the EJB container called those methods. The purpose of this chapter was to show that, despite the complexity of the underlying technology, development of EJBs is not that difficult. The problem is that when EJB-based applications become more complex than this simple example, developers really do need to understand the technology: That’s what the rest of the book is about.
