In this book you'll find nearly 100 servlet examples. The code for these servlets is all contained within the text, but you may prefer to download the examples rather than type them in by hand. You can find the code online and packaged for download at http://www.oreilly.com/catalog/jservlet/. You can also see many of the servlets in action at http://www.servlets.com.
All the examples have been tested using Sun's Java Web Server 1.1.1, running in the Java Virtual Machine (JVM) bundled with the Java Development Kit (JDK) 1.1.5, on both Windows and Unix. A few examples require alternate configurations, and this has been noted in the text. The Java Web Server is free for education use and has a 30-day trial period for all other use. You can download a copy from http://java.sun.com/products. The Java Development Kit is freely downloadable from http://java.sun.com/products/jdk or, for educational use, from http://www.sun.com/products-n-solutions/edu/java/. The Java Servlet Development Kit (JSDK) is available separately from the JDK; you can find it at http://java.sun.com/products/servlet/.
This book also contains a set of utility classes--they are used by the servlet examples, and you may find them helpful for your own general-purpose servlet development. These classes are contained in the com.oreilly.servlet package. Among other things, there are classes to help servlets parse parameters, handle file uploads, generate multipart responses (server push), negotiate locales for internationalization, return files, manage socket connections, and act as RMI servers. There's even a class to help applets communicate with servlets. The source code for the com.oreilly.servlet package is contained within the text; the latest version is also available online (with javadoc documentation) from http://www.oreilly.com/catalog/jservlet/ and http://www.servlets.com.
