here is a site that list free web services. xmethods.net. Oracle JDeveloper has a wizzard where you put in the url (uri?) and it gives you a list of all the available methods. then you are able to call those methods in your code like they were local methods and the wizzard has written code that takes care of all the underlying message and communications protocols (xml and http). It's similar to RMI or CORBA or any other remote procedure call.
