In this chapter, we will discuss how to develop and deploy Java servlets. Servlets allow us, as application developers, to implement server-side logic in Java web and enterprise applications.

Some of the topics covered include:

• An explanation of what servlets are
• Developing, configuring, packaging, and deploying our first servlet
• HTML form processing
• Forwarding HTTP requests
• Redirecting HTTP responses
• Persisting data across HTTP requests
• Initializing servlets via annotations
• Servlet filters
• Servlet listeners
• Servlet pluggability
• Configuring web applications programmatically
• Asynchronous processing
• HTTP/2 server push support
