Sval is a Web service which charts the closing price of a stock listed
on the American Bourses versus the closing values of the DJIA, NASDAQ,
and S&P500 over a given period of time. The chart is returned to the
user as a SOAP message attachment in PNG, JPEG, or SVG format. This
project is a testbed for investigating a wide variety of Web service
technologies by implementing the same Sval Web service using different
architectures.
