Problem with web service proxy and connections.xml

Question

JDev 11.1.14
Hello
I'm trying to create a web service proxy that takes advantage of the connections.xml so that the endpoints can be changed without recompiling the code (as described here http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/web_services.htm#ADFFD548 - 13.2.2 How to Create a New Web Service Connection)
I created the web service proxy using the Jdev wizard and a test client. The access to the web service works as expected.
The client test code is :
package model;
import ch.mit.trac.ws.proxy.*;
import ch.mit.trac.ws.root.Currency;
import javax.naming.NamingException;
public class wsTest {
  public wsTest() {
    super();
  public void testIt() throws NamingException {
    CurrencyConvertor currencyConvertor = new CurrencyConvertor();
    CurrencyConvertorSoap currencyConvertorSoap = currencyConvertor.getCurrencyConvertorSoap();
    Double res = currencyConvertorSoap.conversionRate(Currency.CHF, Currency.USD);
    System.out.println("Hello");
    System.out.println(res);
  public static void main(String [] args) throws NamingException {
    wsTest tt = new wsTest();
    tt.testIt();
}I then create a connection as described in the docs.
I now have a connections.xml as follows:
<?xml version = '1.0' encoding = 'UTF-8'?>
<References xmlns="http://xmlns.oracle.com/adf/jndi">
   <Reference name="CurrencyConvertor" className="oracle.adf.model.connection.webservice.impl.WebServiceConnectionImpl" xmlns="">
      <Factory className="oracle.adf.model.connection.webservice.api.WebServiceConnectionFactory"/>
      <RefAddresses>
         <XmlRefAddr addrType="WebServiceConnection">
            <Contents>
               <wsconnection description="file:/C:/JDeveloper/mywork/WebServiceTest/Model/src/ch/mit/trac/ws/proxy/CurrencyConvertor.wsdl" service="{http://www.webserviceX.NET/}CurrencyConvertor">

                           <operation name="ConversionRate">
                              <soap soapAction="http://www.webserviceX.NET/ConversionRate" xmlns="http://schemas.xmlsoap.org/wsdl/soap/"/>
                              <output name=""/>
                              <input name=""/>
                           </operation>
                        </port>
                        <port name="CurrencyConvertorSoap" binding="{http://www.webserviceX.NET/}CurrencyConvertorSoap">
                           <soap addressUrl="http://www.webservicex.com/CurrencyConvertor.asmx" xmlns="http://schemas.xmlsoap.org/wsdl/soap/"/>
                           <operation name="ConversionRate">

                              <output name=""/>
                              <input name=""/>
                           </operation>
                        </port>
                     </service>
                  </model>
               </wsconnection>
            </Contents>
         </XmlRefAddr>
      </RefAddresses>So far so good.
I then created a new jspx page with a button that calls a method in a request scoped bean.
The method is supposed to use the connections.xml to get the web service proxy in order to call the web service.
The bean code is as follows :
package ch.mit.test;
import javax.faces.event.ActionEvent;
import ch.mit.trac.ws.proxy.*;
import ch.mit.trac.ws.root.Currency;
import javax.naming.Context;
import javax.naming.NamingException;
import oracle.adf.model.connection.webservice.api.WebServiceConnection;
import oracle.adf.share.ADFContext;
public class test {
  public test() {
  public void testIt() throws NamingException {
    Context ctx;
    ctx = ADFContext.getCurrent().getConnectionsContext();
    WebServiceConnection wsc;
    wsc = (WebServiceConnection) ctx.lookup("CurrencyConvertor");
    CurrencyConvertor currencyConvertor = wsc.getJaxWSPort(CurrencyConvertor.class);   -- NPE here
    CurrencyConvertorSoap currencyConvertorSoap = currencyConvertor.getCurrencyConvertorSoap();
    Double res = currencyConvertorSoap.conversionRate(Currency.CHF, Currency.USD);
    System.out.println("Hello");
    System.out.println(res);
  public void testws(ActionEvent actionEvent) {
    try {
      testIt();
    } catch (NamingException e) {
}When running the application and clicking on the button I keep getting the following error at the line marked NPE Here above:

Hi Frank
The page is ADF bound, I've added the page source and the adfc-config source below :
Page
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
          xmlns:f="http://java.sun.com/jsf/core"
          xmlns:h="http://java.sun.com/jsf/html"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
  <jsp:directive.page contentType="text/html;charset=UTF-8"/>
  <f:view>
    <af:document id="d1">
      <af:form id="f1">
        <af:commandButton text="commandButton 1" id="cb1"
                          actionListener="#{test.testws}"/>
      </af:form>
    </af:document>
  </f:view>
</jsp:root>adfc-config
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
  <view id="view1">
    <page>/view1.jspx</page>
  </view>
  <managed-bean id="__4">
    <managed-bean-name id="__3">test</managed-bean-name>
    <managed-bean-class id="__2">ch.mit.test.test</managed-bean-class>
    <managed-bean-scope id="__1">request</managed-bean-scope>
  </managed-bean>
</adfc-config>It seems to be the same sort of problem as in Re: Error in ADF Web Service Connection
