Unable to write client for JAX-WS with Jetty embedded

I've been into this for days: I had a WS initially tested with the JDK deployment (SimpleHttpServerJaxWsServiceExporter). At this point the server and clients worked.

The target environment is not JDK, so I switched to deploying to an embedded Jetty. I used this example for guiding my configuration. I ended up with the following Jetty configuration:

Code:

---

<bean id="jettyServer" class="org.mortbay.jetty.Server"
      init-method="start" destroy-method="stop"> 
    <property name="connectors">
        <list>
            <bean id="Connector"
                  class="org.mortbay.jetty.nio.SelectChannelConnector"
                  p:port="8090" />
        </list>
    </property>
    <property name="handlers">
        <list>
            <bean class="org.mortbay.jetty.servlet.Context">
                <property name="sessionHandler">
                    <bean class="org.mortbay.jetty.servlet.SessionHandler" />
                </property>
                <property name="servletHandler">
                    <bean class="org.mortbay.jetty.servlet.ServletHandler">
                        <property name="servlets">
                            <list>
                                <bean class="org.mortbay.jetty.servlet.ServletHolder"
                                      p:name="spring-ws">
                                    <property name="servlet">
                                        <bean class="org.springframework.ws.transport.http.MessageDispatcherServlet" /> 
                                    </property>
                                    <property name="initParameters">
                                        <map>
                                            <entry key="contextConfigLocation" value="classpath:/jax-ws-embedded-context.xml" /> 
                                        </map>
                                    </property>
                                </bean>
                            </list>
                        </property>
                        <property name="servletMappings">
                            <list>
                                <bean class="org.mortbay.jetty.servlet.ServletMapping"
                                      p:servletName="spring-ws"
                                      p:pathSpec="/*" /> 
                            </list>
                        </property>
                    </bean>
                </property>
            </bean>
            <bean class="org.mortbay.jetty.handler.DefaultHandler" />
            <bean class="org.mortbay.jetty.handler.RequestLogHandler" />
        </list>
    </property>
</bean>

The referred jax-ws-embedded-context.xml is here too:

Code:

---

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
    <description>An endpoint mapping strategy that looks for @Endpoint and @PayloadRoot annotations.</description>
</bean>

<bean class="org.springframework.ws.server.endpoint.adapter.MarshallingMethodEndpointAdapter">
    <description>Enables the MessageDispatchServlet to invoke methods requiring OXM marshalling.</description>
    <constructor-arg ref="marshaller"/>
</bean>

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"
      p:contextPath="br.com.cflex.integration.doc.message" />

<bean id="MPRequestHandler" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition"
      p:portTypeName="MPRequestHandler"
      p:locationUri="/MPRequestHandler/"
      p:createSoap12Binding="true">
    <property name="schemaCollection">
        <bean class="org.springframework.xml.xsd.commons.CommonsXsdSchemaCollection"
                p:inline="true">
                <property name="xsds">
                        <list>
                                <value>classpath:/wsdl/MPRequestHandler_schema1.xsd</value>
                                <value>classpath:/xsd/Acknowledge.xsd</value>
                                <value>classpath:/xsd/CommonData.xsd</value>
                                <value>classpath:/xsd/Messages.xsd</value>
                        </list>
                </property>
        </bean>
    </property>
</bean>

My service seems to be deployed correctly as I can access the WSDL (with XSDs inlined) at http://localhost:8090/MPRequestHandler.wsdl.

But I cannot write a working client configuration. Here is my latest attempt:

Code:

---

<bean id="mpRequestHandlerClient"
        class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
        <property name="serviceInterface" value="br.com.cflex.integration.doc.service.MPRequestHandler" />
        <property name="wsdlDocumentUrl" value="http://localhost:8090/MPRequestHandler.wsdl" />
        <property name="namespaceUri" value="http://www.cflex.com.br/doc/service" />
        <property name="serviceName" value="MPRequestHandler" />
        <property name="endpointAddress" value="http://localhost:8090/MPRequestHandler" />
</bean>

---

When I start this client configuration, I get the following exception:

Code:

---

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mpRequestHandlerClient' defined in class path resource [auv-client-context.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

This NPE says absolutely nothing to me, so does anyone has got a clue about what is wrong?
