In this chapter, we saw that EL 2.2 expressions can be used to dynamically access data (read and write) stored in JavaBeans components, to call arbitrary static and public methods, and to perform arithmetic and logic operations. Finally, we saw that EL allows us to extend its capabilities with custom resolvers. Starting with EL 3.0, we can take advantage of new operators, lambda expressions, and support when working with collection objects.

While reading this book, you will see many examples of EL expressions in real cases. For example, in the next chapter, you will use EL expressions to explore JSF communication capabilities.

See you in the next chapter, where we will discuss JSF communications.
