I have a JAX-WS client that needs to have a modified handler-chain. I am currently doing it by binding this XML when generated the WSDL stubs:

 <jaxws:bindings xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"> 
    <jws:handler-chains xmlns:jws="http://java.sun.com/xml/ns/javaee">
      <jws:handler-chain>
        <jws:handler>
          <jws:handler-name>ServiceRequestServiceClientHandler</jws:handler-name>
          <jws:handler-class>blah.ServiceRequestServiceClientHandler</jws:handler-class>
        </jws:handler>
      </jws:handler-chain>
    </jws:handler-chains>
</jaxws:bindings>

I was looking that the ServiceRequestService_Service object, and it seems like this could be done programmatically (easier in my opinion - less configuration files).

    new ServiceRequestService_Service().getHandlerResolver().getHandlerChain(PORTINFO).add(HANDLER);

But, I do not know what the PortInfo object is, or how to obtain it in relation to the specific service. Has anyone done this?
