gwt-rf-queue

Simple demo http://gwt-rf-queue.appspot.com/ with gwt-rf-queue retrofitted to DynaTableRf.

Features

Pure GWT/Java RequestFactory module for:

• GMail like network retry.
• Detect/retry auth failure.
• Can drive the UI to indicate the RequestFactory is busy or idle.
• Different "quality of service" for different requests.
• Mechanism to send the contents of an Editor tree to the server multiple times and fire different service methods. e.g. to support background validation on the server

Roadmap

• TODO - Semi-respectable unit test coverage.
• TODO - Raise GWT feature requests to add hooks to remove the worst work arounds e.g. custom Processor.
• TODO - Rename AuthFailureDetector to something more generic about "response detector"?
• TODO - Make the demo do something more realistic on auth failure.
• TODO - Put in maven central.

How to use

1. Inherit the module in your gwt.xml file:

<inherits name='uk.ac.diamond.gwt.rf.queue.GwtRfQueue' />

2. Wire up the manager on the client (very minimal, will just do network retry, no UI):

  RequestFactory requestFactory = ...
  QosRequestTransport transport = new QosRequestTransport();
  QosManager manager = new QosManager();
  manager.setRequestTransport(transport);
  QosQueue root = new QosQueue();
  root.setTarget(manager);
  manager.start();
  
  transport.setDefaultSource(root);
  requestFactory.initialize(eventBus, transport);

3. Reference the decorated servlet in your web.xml file:

    <servlet>
        <servlet-name>requestFactoryServlet</servlet-name>
        <servlet-class>uk.ac.diamond.gwt.rf.queue.server.QosRequestFactoryServlet</servlet-class>
    </servlet>
