Java SE 6: Mustang and WS-TMI
Filed under: javase6

Did you know that Java SE 6, Mustang, features a subset of the Java EE Web Services stack ?

I've been tinkering with it, check it: Its JAX-WS (JSR 224) with a helping of JAXB (JSR 222) for its data binding, a good dollop of WS Metadata Annotations (JSR 181), with a sprinkling of a few of its own. Of course you've already teased a coulis of XML strained with WSDL in a JAX-RPC boullion with sun-dried MTOM/XOP and hand-crushed swaRef...

Yawn, W H A T E V E R . Too much information. Way.

Let's try it this way around....you have a neat little program, see ? It does something cute like adding a couple of numbers, which is self-evidently your market-dominating online service in thin disguise:

public class NumberAdderUpperer {

   public int addNumbers(int number1, int number2) {
        return number1 + number2;
    }
}

And naturally, you know you want to tell all your friends to use it, so in Mustang, they made it so you can do this:

import javax.jws.WebService;

@WebService
public class NumberAdderUpperer {

   public int addEmUp(int number1, int number2) {
        return number1 + number2;
    }

}

OK, so now you'd hit deploy in your IDE of course and stick it on the corporate app server, tell the world, and be done. But for the slightly more cautious amongst you, let's you and I do it with nothing more than the Mustang SDK, which has its own mini-Http server just for things like this:-

      import javax.xml.ws.Endpoint;
            ... 
        Endpoint.publish("http://localhost:8080/ws-tmi/adderupperer", new NumberAdderUpperer ());

Oops ! And now your new number adding service is published at:  "http://<hostname>:8080/ws-tmi/adderupperer".

Could it BE any easier ? (actually, maybe you think it could - let me know....)

And I did mention that adding numbers is an incognito book ordering or drug prescription authorisation service, and your soi-disant friends unmasked: they're your customers or patients, right ?

Ya, two imports and an annotation: that's the kind of simplicity I can go for.
