You can also use Jersey to marshall JSON based on jaxb annotations.

This is more specifically how to get around the same origin policy(SOP) of modern browsers using a new concept called JSONP or JSON with Padding. Technically JSONP services are RESTful web services, so it is indeed a web service. If you would like to make an HTTP request like you have suggested in the title provided, you would want to use the included HTTPRequestBuilder. The only problem is that this must obey the SOP. If you would like to access services outside the origin you will have to create a server-side proxy, but the issue with this is that the target service can't be authenticated because the request comes from the server and does not contain the client's credentials. Also, if not implemented properly this can appear to the provider as a DOS attack because all requests are coming from the same machine. I disagree with both titles actually.

As far as I can tell the eval call is necessary to create a unique function name. If you know of a way to create a unique function name I would happily change it in my code. I tried writing a function to do this same thing until I ran into this same problem and went looking and found this class. Thanks, Matt Ray,

It use often soap and wsdl technologies. For a good description of what a webservice is : http://en.wikipedia.org/wiki/Web_service But good tutorial and good site!
