Conclusion

In this chapter you saw how to create a simple Mentawai web application and touched the surface of topics such as actions, input, output, consequence, results, filters, tags, html forms, etc. All these topics will be explored in greater details in later chapters.

You learned that an action (unless it is a POJO action, which can be a misleading name) should not implement the business model of an application. The action should provide the link between the HTTP web request and the business model of a web application.

You also learned about POJO actions, which are actions that are not coupled in any way to the Mentawai framework. The classic scenario is to make your business model become a POJO action so that it will handle the HTTP web requests with the help of filters and without any need for an action.

Before we start exploring some of the Mentawai main features, let's discuss in greater detail the Mentawai architecture so you can have a better foundation to move on.
