29  * This version of the ever so popular GetQuote shows how to use the
30  * Axis client APIs with and without WSDL. The first flavor (getQuote1)
31  * will use WSDL to prefill all of the data about the remote service.
32  * The second one (getQuote2) will do it all manually. Either way the
33  * service is invoked it should produce the exact same request XML and
34  * of course same results.
35  *
36  * This sample supports the use of the standard options too (-p ...)
