Spring is almost a platform rather than a framework. It is far beyond the scope of a single chapter to cover all of Spring's integration and other supporting services.
In this chapter we've seen:
How Spring simplifies working with JMS
How Spring can simplify working with scheduling
How you can send email with Spring
How Spring enables you to define application objects in languages other than Java, within the consistent overall architecture provided by the Spring IoC container
In the next chapter, we'll cover the important topic of security, discussing Acegi Security for Spring, a related project that is used in many Spring projects. We will also briefly introduce Spring RCP: Spring's sister project for developing thick client and standalone GUI applications.
