Source code for the examples in Java Servlet Programming, 2nd Edition are available in one bundle as jservlet2.zip. (ZIP files are readable with the jar program: "jar xvf jservlet2.zip".) The com.oreilly.servlet example code needed to run many of the examples is available separately.

Note: Microsoft Internet Explorer users may have trouble viewing the "Source" links because IE sniffs the content of a page and if it recognizes the type (HTML, etc) IE will override the server Content-Type: text/plain setting and display the page as HTML. When this happens try "View -> Source" to view the actual page source. Don't like it? Complain to Microsoft.
