CHAPTER 21: Sample Application in Detail > Configuration Details
Configuration Details
Having discussed the design details, let's proceed to the configuration of the SpringBlog application. In the following sections, we will discuss the various configurations of the application, from web deployment descriptor to Spring's WebApplicationContext hierarchy.
The Web Deployment Descriptor Configuration
Let's take a look on the web deployment descriptor (web.xml), which is shown in Listing 21-6.
Listing 21-6. The web.xml File
