How do I install the com.oreilly.servlet package?
Unzip the com.oreilly.servlets distribution file using a unzip utility like WinZip or jar. Inside you’ll find a file cos.jar. Place this where your server will find it, such as the WEB-INF/lib directory for your web application. For server-wide availability you can also place it into the CLASSPATH used by your server. That’s it! For more information on the WEB-INF directory see “Java Servlet Programming, 2nd Edition” and for more information on CLASSPATH entries see any introductory Java book.
