Call a web service from Seam

Question

A simple question, but can someone provide a sample code on how someone will call a web service from the JBoss Seam framework and process the results?

I need to be able to integrate with the search platform provided by a private vendor that reveals its functionality as a web service. So, I'm just looking for some recommendations regarding how the code will look for calling this web service.

(As an example, you can choose any sample web service.)

Answer 1

gajillion HTTP- (Restlet , , - ), GET. , HttpClient Apache Commons:

HttpClient client = new HttpClient();
HttpMethod method = new GetMethod("http://api.search.yahoo.com/WebSearchService/V1/webSearch?appid=restbook&query=HttpClient");
client.executeMethod(method);

Answer 2

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! 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());
            }
        }
    }
}
