JAX WS WebServiceClient Problem

We are developing an application in java and since a few weeks ago we have a problem that we are not able to solve.

This is a call to a webservice to obtain a series of data with certificates.

We have followed the following steps for the creation of the artifacts and the subsequent call

wsimport -keep https://xxx/xxx/xxx.svc?singleWsdl -s C:\Users\mvelasco\Documents\xx\xxxx\src\main\java -Xauthfile C:\Users\mvelasco\authwsdl.txt

It generates a series of classes with the structures of the ws and the datacontract.

keytool -importcert -keystore "C:\Program Files\java\jdk1.7.0_60\jre\lib\security\cacerts" -file <ruta certificados> -alias x

private static void llamadaAlServicio() {
  IDocumentosService port = (new DocumentosService())
        .getBasicHttpBindingIDocumentosService();
  BindingProvider prov = (BindingProvider) port;
  log.error("Username: "+ContextProperties.getAsiturWsUsuario());
  log.error("Password: "    +ContextProperties.getAsiturWsPassword());

  prov.getRequestContext().put(BindingProvider.USERNAME_PROPERTY,
        ContextProperties.getAsiturWsUsuario());
  prov.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY,
        ContextProperties.getAsiturWsPassword());

  ArrayOfAttachmentDTO arrAttachmentDTO = port
            .getAllAttachments("1234567");
}

The DocumentService class is generated by JAX-WS

@WebServiceClient(name = "DocumentosService", targetNamespace = "http://tempuri.org/", wsdlLocation = "https://xxx/xxx/xxx.svc?singleWsdl")
public class DocumentosService
    extends Service
{

    private final static URL DOCUMENTOSSERVICE_WSDL_LOCATION;
    private final static WebServiceException DOCUMENTOSSERVICE_EXCEPTION;
    private final static QName DOCUMENTOSSERVICE_QNAME = new QName("http://tempuri.org/", "DocumentosService");

    static {
        URL url = null;
        WebServiceException e = null;
        try {
            url = new URL("https://xxx/xxx/xxx.svc?singleWsdl");
        } catch (MalformedURLException ex) {
            e = new WebServiceException(ex);
        }
        DOCUMENTOSSERVICE_WSDL_LOCATION = url;
        DOCUMENTOSSERVICE_EXCEPTION = e;
    }

    public DocumentosService() {
        super(__getWsdlLocation(), DOCUMENTOSSERVICE_QNAME);
    }

    public DocumentosService(WebServiceFeature... features) {
        super(__getWsdlLocation(), DOCUMENTOSSERVICE_QNAME, features);
    }

    public DocumentosService(URL wsdlLocation) {
        super(wsdlLocation, DOCUMENTOSSERVICE_QNAME);
    }

    public DocumentosService(URL wsdlLocation, WebServiceFeature... features) {
        super(wsdlLocation, DOCUMENTOSSERVICE_QNAME, features);
    }

    public DocumentosService(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }

    public DocumentosService(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
        super(wsdlLocation, serviceName, features);
    }

    /**
     * 
     * @return
     *     returns IDocumentosService
     */
    @WebEndpoint(name = "BasicHttpBinding_IDocumentosService")
    public IDocumentosService getBasicHttpBindingIDocumentosService() {
        return super.getPort(new QName("http://tempuri.org/", "BasicHttpBinding_IDocumentosService"), IDocumentosService.class);
    }

    /**
     * 
     * @param features
     *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.
     * @return
     *     returns IDocumentosService
     */
    @WebEndpoint(name = "BasicHttpBinding_IDocumentosService")
    public IDocumentosService getBasicHttpBindingIDocumentosService(WebServiceFeature... features) {
        return super.getPort(new QName("http://tempuri.org/", "BasicHttpBinding_IDocumentosService"), IDocumentosService.class, features);
    }

    private static URL __getWsdlLocation() {
        if (DOCUMENTOSSERVICE_EXCEPTION!= null) {
            throw DOCUMENTOSSERVICE_EXCEPTION;
        }
        return DOCUMENTOSSERVICE_WSDL_LOCATION;
    }

}

4.The PROBLEM is that from our machines in local windows we get the ws to respond correctly with this implementation. However, when we went into pre-production environments under Linux, we could not connect. The trace that appears is the following

We have been stuck with this problem for weeks. Any kind of help would be appreciated. Greetings and thanks
