After you have set up the CLASSPATH in your environment, to invoke this sample using WSIF's DII, run the DynamicInvoker class. Specify as command line arguments the location of the WSDL file for the stockquote sample followed by the operation you wish to invoke and the symbol for the company whose stockquote you are interested in. For example,
java clients.DynamicInvoker samples/simplesoap/StockquoteSOAP.wsdl getQuote IBM
