[SOLVED] Java - Send SOAP header (for authentication)

I've generated some Java code from a wsdl file and the request itself seems to be working, but I can't send my credentials.

I've tested the Webservice with a tool called "SoapUI" and everything seemes to be working like a charm.

Here is an example of the (working) xml:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:beac="url">
  <soapenv:Header>
    <nsAuthn:authnHeader xmlns:nsAuthn="url/auth">
      <nsAuthn:id>id</nsAuthn:id>
      <nsAuthn:password>password</nsAuthn:password>
    </nsAuthn:authnHeader>
  </soapenv:Header>
  <soapenv:Body>
    <beac:getData>
      <saisonid>int</saisonid>
    </beac:getData>
  </soapenv:Body>
</soapenv:Envelope>

And this is my attempt:

public RankDtoResponse getData(int saisonid) throws java.rmi.RemoteException, SOAPException {
    if (super.cachedEndpoint == null) {
        throw new org.apache.axis.NoEndPointException();
    }

    SOAPHeaderElement authentication = new SOAPHeaderElement("url","auth");
    SOAPHeaderElement user = new SOAPHeaderElement("url","id", "id");
    SOAPHeaderElement password = new SOAPHeaderElement("url","password", "password");
    try {
        authentication.addChild(user);
        authentication.addChild(password);
    } catch (SOAPException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    org.apache.axis.client.Call _call = createCall();
    _call.setOperation(_operations[3]);
    _call.setUseSOAPAction(true);
    _call.setSOAPActionURI("");
    _call.setEncodingStyle(null);
    _call.setProperty(org.apache.axis.client.Call.SEND_TYPE_ATTR, Boolean.FALSE);
    _call.setProperty(org.apache.axis.AxisEngine.PROP_DOMULTIREFS, Boolean.FALSE);
    _call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS); 
    _call.setOperationName(new javax.xml.namespace.QName("url", "getData"));


    setHeader(authentication);
    setRequestHeaders(_call);
    setAttachments(_call);
    try {        java.lang.Object _resp = _call.invoke(new java.lang.Object[] {new java.lang.Integer(saisonid)});

    if (_resp instanceof java.rmi.RemoteException) {
        throw (java.rmi.RemoteException)_resp;
    }
    else {
        extractAttachments(_call);
        try {
            return (RankDtoResponse) _resp;
        } catch (java.lang.Exception _exception) {
            return (RankDtoResponse) org.apache.axis.utils.JavaUtils.convert(_resp, RankDtoResponse.class);
        }
    }
    } catch (org.apache.axis.AxisFault axisFaultException) {
      if (axisFaultException.detail != null) {
        if (axisFaultException.detail instanceof java.rmi.RemoteException) {
          throw (java.rmi.RemoteException) axisFaultException.detail;
        }
        if (axisFaultException.detail instanceof SOAPException) {
          throw (SOAPException) axisFaultException.detail;
        }
    }
    throw axisFaultException;
  }  
}

Most of the code is autogenerated from a wsdl file by wsdl2java.

Do you need any more information? Am I missing something out?

Thanks in advance
