Setting a custom HTTP header dynamically with Spring-WS client

ClientInterceptor works great for static header value. But it is not possible to use it when a different value should be applied per each request. In that case WebServiceMessageCallback is helpful:

final String dynamicParameter = //...

webServiceOperations.marshalSendAndReceive(request, 
    new WebServiceMessageCallback() {
        void doWithMessage(WebServiceMessage message) {
            TransportContext context = TransportContextHolder.getTransportContext();
            CommonsHttpConnection connection = (CommonsHttpConnection) context.getConnection();
            PostMethod postMethod = connection.getPostMethod();
            postMethod.addRequestHeader( "fsreqid", dynamicParameter );
        }
}

public class AddHttpHeaderInterceptor implements ClientInterceptor {

public boolean handleFault(MessageContext messageContext)
        throws WebServiceClientException {
    return true;
}

public boolean handleRequest(MessageContext messageContext)
        throws WebServiceClientException {
     TransportContext context = TransportContextHolder.getTransportContext();
     HttpComponentsConnection connection =(HttpComponentsConnection) context.getConnection();
     connection.addRequestHeader("name", "suman");

    return true;
}

public boolean handleResponse(MessageContext messageContext)
        throws WebServiceClientException {
    return true;
}

}

    <bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
    ...
    <property name="interceptors">
        <list>
            <bean class="com.blah.AddHttpHeaderInterceptor" />
