In this chapter, we discussed the e-mail support in Spring and JMS in Spring. We took a look at the JavaMail API and Spring API for JavaMail. Then, we developed a Spring Mail Application. We discussed Spring Java Message Service and understood message, messaging, and JMS components. We took a look at the MOM Service Provider and configured ActiveMQ. We also developed an application to perform messaging using a Spring JMS Template. Then, we discussed the exception on running the application.

In the next chapter, we will go through the solutions of all the exercises given thus far.
