In this chapter, we went through the EJB basics and changes in EJB 3.2 by following a simple lab example, which was enriched progressively. This example showed how the Maven project can be used from within the Eclipse environment to assist you in assembling the project with all the necessary dependencies.

Up to now, we have just coded a remote standalone client for our application. In the next chapter, we will see how to add a web frontend to our example using the context and dependency injections, to bridge the gap between the web tier and enterprise tier.
