Appel d'un webservice

**tweetysat** · 10/10/2011, 14h14

Bonjour.
Je suis en train de me familiariser avec les webservices.
Pour commencer j'ai essayé simplement avec ceci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

package be.toto.webservice;
 
import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
 
@Stateless
@WebService
public class Toto
{
	@WebMethod
	public String sayHello()
	{
		System.out.println("--Hello World Web Service--");
		return "Hello World Web Service";
	}
 
}

et dans le pom.xml

Code :

    	<dependency>
      		<groupId>axis</groupId>
      		<artifactId>axis-jaxrpc</artifactId>
      		<version>1.4</version>
    	</dependency>
  	<dependency>
      		<groupId>axis</groupId>
      		<artifactId>axis</artifactId>

   		<artifactId>javaee-api</artifactId>

  	</dependency>
</dependencies>

Après le package, je déploie je jar sur un serveur glassfish 3.0.1.
Dans la console, l'application est bien déployée, je vois le bean toto.
Dans show end point j'ai :
...
Tester /TotoService/Toto?Tester
WSDL /TotoService/Toto?wsdl
...
les deux liens fonctionnent. Avec le tester il m'affiche bien la fonction sayHello(). Quand je clique dessus :

Code :

Method returned
java.lang.String : "Hello World Web Service"
SOAP Request
 
    <?xml version="1.0" encoding="UTF-8"?>
    <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
        <S:Header/>
        <S:Body>
            <ns2:sayHello xmlns:ns2="http://webservice.toto.be/"/>
        </S:Body>
    </S:Envelope>
 
SOAP Response
 
    <?xml version="1.0" encoding="UTF-8"?>
    <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
        <S:Body>
            <ns2:sayHelloResponse xmlns:ns2="http://webservice.toto.be/">
                <return>Hello World Web Service</return>
            </ns2:sayHelloResponse>
        </S:Body>
    </S:Envelope>

et j'ai bien le sysout dans le log.

Ensuite j'essaie ceci :

public class App
{
	public static void main(String[] args) throws Exception
	{
		String endPoint = "http://127.0.0.1:8080/TotoService/Toto";
 
		Service service = new Service();
		Call call = (Call) service.createCall();
		call.setTargetEndpointAddress(new java.net.URL(endPoint));
		call.setOperationName("sayHello");
		System.out.println(call.invoke(new Object[0]));
 
	}
 
}

Mais ça ne marche pas :

et le sysout n'apparaît pas dans le log. Donc le service ne s'exécute pas.
Mais pourquoi ?
Y'a un problème avec le end point ?
Des idées ?

Merci.
