container, spring is often considered a substitute for ejbs. We think spring as a container for many applications and usage scenarios, combined with its rich support capabilities, is a better choice in the areas of things, ORM, and JDBC access. However, it must be noted that using spring does not prevent you from using EJBS. In fact, spring makes it easier to access EJBS and implement EJBS and its functions. In this chapter, we'll look at how spring can help you access and implement EJBS. Sprin
