Servlet Error

First, a useless post because I can't post a thread with URL if this is my first post....

Hi guys, sorry for my english...

I just decided to post here because after passing 2 days debugging, I finally admit that I need some help. I am a beginner in Java and Spring and don't find a lot of documentation/tutorial for spring-ws, the few sources I found are maven based and I got a firewall which blocks all the jar downloading need by the projects (not sure my sentence is very clear, sorry...)

I must develop some Web services using spring-ws and I get a short example code to learn how spring-ws works (or not works actually), composed of a web service and a client. I apologize for asking such help but I really don't get it.

Here is the code of the webservice:

spring-ws-servlet.xml:

First, I had the

<oxm:jaxb2-marshaller id="marshaller" >
		<oxm:class-to-be-bound
			name="fr.bdf.modec.service.model.util.NombreUtilisateurs" />
		<oxm:class-to-be-bound
			name="fr.bdf.modec.service.model.util.NombreUtilisateursResponse" />
	</oxm:jaxb2-marshaller>

but I had an error:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'oxm:jaxb2-marshaller'

so I put:

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
            <list>                <value>fr.bdf.modec.service.model.util.NombreUtilisateurs</value>
                <value>fr.bdf.modec.service.model.util.NombreUtilisateursResponse</value>
            </list>
        </property>
        <property name="schema" value="classpath:org/springframework/oxm/schema.xsd"/>
    </bean>

instead because I didn't understand the error and thinks it was kindda similar, am I good?

So config is over, Here's my Endpoint:

public class UtilisateurEndPoint extends AbstractJDomPayloadEndpoint{

	/**
	 *
	 */
	private Jaxb2Marshaller marshaller;

	public Jaxb2Marshaller getMarshaller() {
		return marshaller;
	}

	public void setMarshaller(Jaxb2Marshaller marshaller) {
		this.marshaller = marshaller;
	}

protected Element invokeInternal(Element entree) throws Exception {

return null; //just for testing
}
}

For what I understood, MessageDispatcherServlet takes control when a request is coming, creates beans, and then looks for Endpoint, then the Endpoint which extends AbstractJDomPayloadEndpoint unmarshall request, treats request, buld response and send it to the client, am I good?

Here is the client code:

public void customSendAndReceive() {
StreamSource source = new StreamSource(new StringReader(MESSAGE));
StreamResult result = new StreamResult(System.out);
WebServiceMessageCallback wsmc = new WebServiceMessageCallback() {

public void doWithMessage(WebServiceMessage message)
					throws IOException, TransformerException {
Result res = message.getPayloadResult();
AbstractSoapMessage abstractSoapMessage = (AbstractSoapMessage) message;
SoapHeader entete = abstractSoapMessage
						.getSoapHeader();
				abstractSoapMessage.getSoapBody().addNamespaceDeclaration("tt", "http://fr.bdf.modec/utilisateur/");
				abstractSoapMessage.setSoapAction("http://fr.bdf.modec/utilisateur/");
				System.out.println(res);
			}
		};
		try {
			FaultMessageResolver fmr = new FaultMessageResolver(){
	public void resolveFault(WebServiceMessage message)	throws IOException {
DOMResult res=(DOMResult) message.getPayloadResult();
System.out.println("Interception de la faute"+res);
DOMBuilder db = new DOMBuilder();

SaajSoapMessage saajSoapMessage = (SaajSoapMessage) message;
String test = saajSoapMessage.getFaultReason();
Source src = message.getPayloadSource();
System.out.println("source de l'erreur "+test+" "+src);
				}
			};

webServiceTemplate.sendSourceAndReceiveToResult("http://localhost:8080/ModecWS",source, result);
		} catch (Exception e) {
			System.out.println("ERREUR interceptee");
			System.out.println("## CODE ## " + e.getMessage());
			System.out.println("## Local M ## " + e.getLocalizedMessage());
			e.printStackTrace();
		}
	}

Executing this client results in a:
ERREUR interceptee
## CODE ## Erreur Interne de Servlet [500]
## Local M ## Erreur Interne de Servlet [500]

If somebody find the time to help me, I'll be really grateful.

Thanks.
