<p>A simple question, but could someone provide sample code as to how would someone call a web service from within the JBoss Seam framework, and process the results?</p>

<p>I need to be able to integrate with a search platform being provided by a private vendor who is exposing his functionality as a web service. So, I'm just looking for some guidance as to what the code for calling a given web service would look like. </p>

<p>(Any sample web service can be chosen as an example.)</p>

```
```
import org.restlet.Client;
import org.restlet.data.Protocol;
import org.restlet.data.Reference;
import org.restlet.data.Response;
import org.restlet.resource.DomRepresentation;
import org.w3c.dom.Node;

/**
 * Uses YAHOO!'s RESTful web service with XML.
 */
public class YahooSearch {
    private static final String BASE_URI = "http://api.search.yahoo.com/WebSearchService/V1/webSearch";

    public static void main(final String[] args) {
        if (1 != args.length) {
            System.err.println("You need to pass a search term!");
        } else {
            final String term = Reference.encode(args[0]);
            final String uri = BASE_URI + "?appid=restbook&query=" + term;
            final Response response = new Client(Protocol.HTTP).get(uri);
            final DomRepresentation document = response.getEntityAsDom();

            document.setNamespaceAware(true);
            document.putNamespace("y", "urn:yahoo:srch");

            final String expr = "/y:ResultSet/y:Result/y:Title/text()";
            for (final Node node : document.getNodes(expr)) {
                System.out.println(node.getTextContent());
            }
        }
    }
}
```
```
This code uses
Restlet
to make a request to Yahoo's RESTful search service. Obviously, the details of the web service you are using will dictate what your client for it looks like.
