/**
 * This version of the ever so popular GetQuote shows how to use the
 * Axis client APIs with and without WSDL.  The first flavor (getQuote1)
 * will use WSDL to prefill all of the data about the remote service.
 * The second one (getQuote2) will do it all manually.  Either way the
 * service is invoked it should produce the exact same request XML and
 * of course same results.
 *
 * This sample supports the use of the standard options too (-p ...)
