Summary

This chapter discussed the way JDBC is used in the context of Enterprise JavaBeans. An overview of the different bean types and database access available in the EJB framework showed that developers face several choices when choosing to develop with J2EE application servers. Of course, usual JDBC code can be used in J2EE components, but what you were introduced to in this chapter shows that a great deal of the complexity of accessing databases from Java objects has been addressed by the designers of J2EE. It is therefore possible to hide such complexity in both container-managed entity beans and bean-managed entity beans.

The next chapter provides examples that illustrate several techniques discussed in previous chapters.
