In this chapter, we looked at how to create multi-module EJB projects using both standard NetBeans projects and Maven. We saw how these projects can contain multiple modules and how the Maven multi-module project type is especially powerful as it allows an almost unlimited project hierarchy to be created. We also noted that for simpler projects, a simple .War file deployment may be sufficient instead of a multi-module EJB project.

We looked at the different types of EJBs that can be created within NetBeans and created an example project to deploy an EJB and then invoke it from a remote client. We also saw how we can use NetBeans to easily generate a session bean façade for the existing @Entity classes within our applications.

Finally, we looked at some of the more advanced and newer features of Java EE. We saw how NetBeans can help us perform bean validation and create new bean validation constraints, and how it can be helpful when using CDI within our applications.
