How to consume this asynchronous web service?

[W Pacharoen]

I want to invoke the asynchronous web service that is implemented by BPEL as following:

This is the WSDL of this service.

    
<?xml version="1.0" encoding="UTF-8"?>

    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
    <types/>
    
    <message name="AsynchronousServiceOperationRequest">
        <part name="request" type="xsd:string"/>
    </message>
    <message name="AsynchronousServiceOperationReply">
        <part name="response" type="xsd:string"/>
    </message>

        </operation>
    </portType>
    <portType name="AsynchronousServiceCallBackPT">

    </binding>
    
    <service name="AsynService">
        <port name="AsynServicePort" binding="tns:AsynServiceBinding">
            <soap:address location="http://localhost:8080/Asynchronous1/AsynchronousService/AsynService"/>
        </port>
        <port name="AsynServiceCallBackPort" binding="tns:AsynServiceCallBackBinding">
            <soap:address location="http://localhost:8080/Asynchronous1/AsynchronousService/AsynServiceCallBack"/>
        </port>
    </service>
    
    <plnk:partnerLinkType name="AsynchronousServicePL">              
        <plnk:role name="serviceProvider"

        </plnk:role>
        <plnk:role name="serviceRequestor"

</definitions>

This is the BPEL of this service. (If you want to implement, if not you can skip the following code.)

   
<?xml version="1.0" encoding="UTF-8"?>
<process
    name="AsynchronousService"
    targetNamespace="http://enterprise.netbeans.org/bpel/Asynchronous1/AsynchronousService"
    xmlns="http://docs.oasis-open.org/wsbpel/2.0/process/executable"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:tns="http://enterprise.netbeans.org/bpel/Asynchronous1/AsynchronousService">
        
    <import namespace="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
            location="AsynchronousService.wsdl" 
            importType="http://schemas.xmlsoap.org/wsdl/"/>
    
    <partnerLinks>
        <partnerLink name="PartnerLink1" 
            xmlns:tns="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
            partnerLinkType="tns:AsynchronousServicePL" 
            myRole="serviceProvider" 
            partnerRole="serviceRequestor"/>
    </partnerLinks>
    
    <variables>
        <variable name="AsynchronousServiceCallBackOut" 
                  xmlns:tns="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
                  messageType="tns:AsynchronousServiceOperationReply"/>
        <variable name="AsynchronousServiceOperationIn" 
                  xmlns:tns="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
                  messageType="tns:AsynchronousServiceOperationRequest"/>
    </variables>
    
    <sequence>
        <receive name="Receive1" 
                 createInstance="yes" 
                 partnerLink="PartnerLink1" 
                 operation="AsynchronousServiceOperation" 
                 xmlns:tns="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
                 portType="tns:AsynchronousServicePT" 
                 variable="AsynchronousServiceOperationIn"/>
        <assign name="Assign1">
            <copy>
                <from variable="AsynchronousServiceOperationIn" part="request"/>
                <to variable="AsynchronousServiceCallBackOut" part="response"/>
            </copy>
        </assign>
        <invoke name="Invoke1" 
                partnerLink="PartnerLink1" 
                operation="AsynchronousServiceCallBack" 
                xmlns:tns="http://j2ee.netbeans.org/wsdl/AsynchronousService" 
                portType="tns:AsynchronousServiceCallBackPT" 
                inputVariable="AsynchronousServiceCallBackOut"/>
    </sequence>
</process>

To note that, both request and response of this service are one way operation.
How do I write a Java web service (by e.g. JAX-WS, JAXB, etc.) to invoke this kind of asynchronous call back operation ("AsynchronousServiceCallBack" operation)?

Thank you in advance.
