The Book
Chapter 2 Examples from Java Servlet Programming, 2nd Ed

  • 2-1: A servlet that prints "Hello World"
  • 2-3: A servlet that knows to whom it's saying hello, modified to return quickly in response to HEAD requests

Examples from other chapters:

Example 2.1: A servlet that prints "Hello World."
This servlet prints a simple hello world. Note that the book has an interesting history on the first documented "Hello World!" program.

Example 2.3: A servlet that knows to whom it's saying hello, modified to return quickly in response to HEAD requests
This servlet uses the request's getMethod() method to improve performance by detecting HEAD requests in the doGet() method so that it can return early.
