Lab #2 - Introduction to Servlet Technology

CS 183 - Hypermedia and the Web

The goal of this laboratory assignment is to gain familiarity with starting the Tomcat server, and with creating and executing a simple servlet you have written.

If you are performing the assignment on the CATS machines, you should first perform the following setup steps.

Note: CATS has requested that students in CS 183 not run the Tomcat server on the machine unix.ic. Instead, please run the Tomcat server on an individual workstation in one of the labs. Effectively, this means you'll need to perform your lab assignment (or at least test it, prior to submission) in one of the CATS labs.

There is only one part to this lab assignment.

1. Modify the SAX parser from the first lab assignment so that it:

• Runs as a servlet, instead of a standalone Java program
• Reads the XML file from a URL (i.e., using HTTP), rather than from a file.

Note that the XERCES SAX parser already supports reading an XML file via HTTP from a URL.

Additional Information

• A sample solution to the SAX parsing problem from the first assignment can be found here.
• The currency converter application, as found in the Tomcat Kick Start book, on pages 60-61, doesn't work on our version of Tomcat. Mark Slater has created a working copy of this applet, which you can use to deploy a sample applet. For instructions on how to use and deploy this applet, go here.
