Error in ADF Web Service Connection

Question

Hello everyone.
I have the following problem.
Create a "Web Services Proxy" to consume a Web Services outside the application.
Web services require authentication and create a Web ADF Services Connection to authenticate, but when you programmatically use the ADF Web Service Connection I get the following error:
java.lang.NullPointerException
     at java.lang.Class.isAssignableFrom(Native Method)
     at oracle.j2ee.ws.common.jaxws.runtime.GenericJavaType.create(GenericJavaType.java:97)

     at edu.esade.portal.wsclient.wordpress.WordPressCliente.main(WordPressCliente.java:167)
The code I use to get the connection is:
private DatosBlogsBndQSService getDatosBlogsBndQSService () {
Context ctx;
try {
ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("DatosBlogsBndQSService");
System.out.println("wsc:"+wsc.toString());
DatosBlogsBndQSService proxy = wsc.getJaxWSPort(DatosBlogsBndQSService.class); // line 62
return proxy;
} catch (NamingException e) {
e.printStackTrace();
return null;
Finalmente la configuración del recurso es:
<Reference name="DatosBlogsBndQSService" className="oracle.adf.model.connection.webservice.impl.WebServiceConnectionImpl" credentialStoreKey="DatosBlogsBndQSService" xmlns="">
<Factory className="oracle.adf.model.connection.webservice.api.WebServiceConnectionFactory"/>

<operation name="listarBlogs">

<output name=""/>
<input name=""/>
</operation>
</port>
</service>
</model>
</wsconnection>
</Contents>
</XmlRefAddr>
<SecureRefAddr addrType="transportPassword"/>
<SecureRefAddr addrType="transportUserName"/>
</RefAddresses>
</Reference>
When the Web Service did not require authentication to work without problem, the error arises when you need to login and use the "ADF Web Services Connection", is there some other way to log in using the Web Service proxy client directly?
Any help is welcome.
Regards.

Hi Shay.
I not use Web service data control, I use only Web Service proxy and the client class for populate data to view object programmatically.
However, in a test class do I have this:
public class WordPressCliente {
private final static Logger logger = Logger.getLogger(WordPressCliente.class);
public WordPressCliente() {
super();
private DatosBlogsBndQSService getDatosBlogsBndQSService () {
Context ctx;
try {
ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("DatosBlogsBndQSService");
System.out.println("wsc:"+wsc.toString());
DatosBlogsBndQSService proxy = wsc.getJaxWSPort(DatosBlogsBndQSService.class);
return proxy;
} catch (NamingException e) {
e.printStackTrace();
return null;
private DatosBlogsPT getDatosBlogsPortClient() throws Exception {

URL url = new URL(baseUrl,ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress"));

System.setProperty("http.username", "atsistemas");
System.setProperty("http.password", "atsistemas2011");
DatosBlogsBndQSService integracionWordpress = new DatosBlogsBndQSService(url,qName);
DatosBlogsPT wordpressPT = integracionWordpress.getDatosBlogsBndQSPort();
if (ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress.autenticacion").equals("true")) {
System.out.println("hay que validar el WS");
BindingProvider bp = (BindingProvider)wordpressPT;
bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress.usuario"));
bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress.clave"));

return wordpressPT;
