 package org.jboss.remoting.samples.callback.statistics;
 
 
Sample client that demonstrates CallbackPoller tuning statistics.

Author(s):
Ron Sigal
Tom Elrod
 
 public class CallbackClient
 {
    // Default locator values
    private static String transport = "socket";
    private static String host = "localhost";
    private static int port = 5400;


   
Registers callback listener and asks CallbackPoller to print statistics.
 
    public void getPolledCallbacks(String locatorURIthrows Throwable
    {
       ..println("Calling remoting server with locator uri of: " + locatorURI);
       InvokerLocator locator = new InvokerLocator(locatorURI);
       Client client = new Client(locator);
       client.connect();
       
       // Registter callback handler and tell CallbackPoller to report statistics.
       CallbackHandler callbackHandler = new CallbackHandler();
       HashMap metadata = new HashMap();
       metadata.put(."true");
       client.addListener(callbackHandlermetadata);
 
       // Wait for callbacks to received, processed, and acknowledged.
       Thread.sleep(20000);
 
       // remove callback handler from server
       client.removeListener(callbackHandler);
       client.disconnect();
    }


   
Can pass transport and port to be used as parameters.
 
    public static void main(String[] args)
    {
       if(args != null && args.length == 2)
       {
           = args[0];
           = Integer.parseInt(args[1]);
       }
       String locatorURI =  + "://" +  + ":" + ;
       CallbackClient callbackClient = new CallbackClient();
       try
       {
          callbackClient.getPolledCallbacks(locatorURI);
       }
       catch(Throwable e)
       {
          e.printStackTrace();
       }
    }

   
Our implementation of the InvokerCallbackHandler. Simply prints out the callback object's message upon receiving it.
 
    public class CallbackHandler implements InvokerCallbackHandler
   {
      public void handleCallback(Callback callbackthrows HandleCallbackException
      {
         // Slow down callback handling so callbacks build up in CallbackPoller.
         try
         {
            Thread.sleep(1000);
         }
         catch (InterruptedException e) {}
         ..println("Received push callback.");
         ..println("Received callback value of: " + callback.getCallbackObject());
         ..println("Received callback server invoker of: " + callback.getServerLocator());
      }
   }
