In this chapter, we continue our in-depth survey of Java MVC. We talk about some topics that you’ll encounter less frequently compared to the topics discussed in the last chapter, but that could be important to your project, depending on the circumstances. This includes bean validation, injectable context, partial page updates, and observer classes. We also deepen our knowledge about state handling, and we include some configuration topics.
