WSDL Proxy – Making your WSDL application Ajax-portable

Ok, so you want to access a WSDL source and consume it in your web application, using Javascript. With a very nice Javascript SOAP Client available, everything looks peachy, safe and well documented. Except it uses Ajax, and inherently XHR (XML HTTP Request), which cannot reach cross domain. That’s a bugger, of course, because the whole point of WSDL and Web Services in general is to be available to any number of consumers far and wide, from granny to Mars. So, how do we deal with that?

WSDL Web Service querying a DB (Eclipse w/ client in PHP)

Prologue: I started out as your average guy with solid knowledge in WSDL and web services, to test out and build a minimal database connected service in Eclipse, and consume it in a web application somewhere else (anywhere else to be more specific, that is to make the data source available to any number of web servers having our application installed). And the reason I wrote this article is that I’ve had about three hours of “feeling dumb” penitence doing just that.
