Two web services are involved in creating the above output -- a web service that retrieves Shakespeare quotations (WSDL) and a web service that translates from English to Pig Latin (WSDL). I used NetBeans IDE 4.1 to consume the web services, which means that my complete ignorance of SOAP was not an obstacle -- a wizard did most of the work and all I had to do was add some code to process the data returned from the web services.
I find it a little bit disconcerting that, after digging through a lot of web services, I can say with a reasonable degree of confidence that the only reliable web service that translates English into any other language is one that translates it into Pig Latin. How bizarre! All other -- without a single exception -- translation web services just don't work.
