Raymond beat me to it but since I already wrote most of this up, here are the
steps that I've used in the past (these are the same things used by the sample
that Raymond is referring to):
1.) Get the WSDL for the service you want to access
2.) Run wsimport on the WSDL
3.) Add an attribute (for the reference) to your component of the service
interface type that was generated via wsimport and use the Reference
annotation. So something like:
import org.osoa.sca.annotations.Reference;
import com.ext.FooService;
public class SomeComponent implements SomeService {
@Reference
protected FooService fooService;
...
}
4.) Add the reference info to the component in your .composite file:
<component name="SomeComponent">
<implementation.java class="bar.SomeComponent" />
<reference name="fooService">
<binding.ws
wsdlElement="http://ext.com#wsdl.port(SvcName/PortName)"
uri="http://somehost/FooService"; />
</reference>
</component>
So, when your composite app loads up, the runtime will take care of populating
the reference with a valid WS client pointing to the endpoint specified in your
.composite file. If you leave off the uri attribute, I believe whatever
endpoint was specified in the original WSDL will be used.

Subject: Re: reference to jax-ws external web service (calling it)
Please take a look at the sample at [1]. It uses "wsimport" to generate java
interfaces from a WSDL, and use it to talk to external weather WS using
Tuscany SCA.
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0";
targetNamespace="http://weather"; name="WeatherForecast">
<component name="WeatherForecastService">
<implementation.java class="weather.WeatherForecastImpl" />
<reference name="weatherForecast">
<binding.ws
wsdlElement="http://www.webservicex.net#wsdl.port(WeatherForecast/WeatherForecastSoap)"
/>
</reference>
</component>
</composite>
Please note binding.ws is used.
