Consumption problem of a SOAP web service

Question

My mission is to develop a web application using JSF2, EJB3 on a JBOSS7 application server.
The application is very simple, however I have to consume a web service developed by other people (soap / wsdl).
With the help of SOAPUI, the said web service works perfectly. The problem: when integrating into a Java code, the error message is displayed: " The server sent HTTP status code 404: null"
Can I have your advice?
Thank you

WSDL enter image description here
Test with SoapUi: enter image description here
Note: During the test phase with soapUi, you must manually integrate the endpoint URL and the soapaction value.

Class : ResponseHeader.java

package com.myproject.site;

public class ResponseHeader {
    private int code;
    public ResponseHeader() {
        super();
        // TODO Auto-generated constructor stub
    }

    public ResponseHeader(int code) {
        super();
        this.code = code;
    }

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

}

Interface SiteService.java:

package com.myproject.site;

@WebService(targetNamespace = "http://www.monsite.com/webservices/app-homeSecurityValidation-ws", name = "app-homeSecurityValidation-ws")
public interface SiteService {

    @WebMethod
    public ResponseHeader HomeSecurityValidationRequest(
        @WebParam(name = "verif", targetNamespace = "")
        java.lang.String verif,
        @WebParam(name = "login", targetNamespace = "")
        java.lang.String account,
        @WebParam(name = "password", targetNamespace = "")
        java.lang.String password
    ) ;
