Dynamic Endpoints

[John Baker]

Hi,

I'm trying to simplify the configuration of a pre-packaged Axis server which
already has a bunch of services deployed. I'd like users to be easily be
able to set the endpoint on services that were generated from wsdl, so I'm
using the Java stub as my deployed service. You can think of this model as a
proxy, in a rather simple sense; it does nothing more than call the same
service on another server.

I appreciate that it's possible to set an endpoint for a service through a
deploy.wsdd file. However I would like to do this dynamically and am
wondering how I would do this? I think I need to set the parameter
dynamically so everytime an instance of a service is created, an endpoint is
set.

I've got something like this:

org.apache.axis.client.Service service =  
  org.apache.axis.client.ServiceFactory.getService("MyService");
  Iterator pi = service.getPorts();
  javax.wsdl.Port port;
  while (pi.hasNext())
  {
    port = (javax.wsdl.Port)pi.next();
    port.addExtensibilityElement(new 
SOAPAddressImpl("http://localhost:9090/hello";));
}

But I suspect it would have to be a little more advanced than my simple
example :)

I'd also need to write my own SOAPImpl:

protected class SOAPAddressImpl implements 
javax.wsdl.extensions.soap.SOAPAddress
{
  private QName elementType;
  private Boolean required;
  private String uri;
                     
  public SOAPAddressImpl(String uri)
  { this.uri = uri; }
                                 
  public void setElementTpe(QName elementType)
  { this.elementType = elementType; }
      
  public QName getElementType()
  { return (elementType); }
                  
  public void setRequired(Boolean required)
  { this.required = required; }
                              
  public Boolean getRequired()
  { return (required); }
                                          
  public void setLocationURI(String uri)
  { this.uri = uri; }
      
  public String getLocationURI()
  { return (uri); }
}
                     
But I'm not sure what the elementType of required flag would require? Having
read the Axis source, I don't think they are used by the client.Service class 
anyway.

Any thoughts/pointers?

Thanks,
