That's exactly what I needed.  Thanks!-TomOn 7/11/06, Matt Chotin <[EMAIL PROTECTED]> wrote:













  


    
            









Do you want it to be a destination or just
a class that is around at startup?  If it will be a destination you can
set the scope to application for it and I believe it will get created as the
server starts up.  If your class won't be a destination the
traditional way to get a class loaded is to have a servlet kick it into gear.  You
have the servlet get preloaded and then make sure that the servlet does
whatever kickoff is needed.  Check the web.xml that we ship in flex.war, I
believe the MessageBrokerServlet gets preloaded.  There may be other ways
to do this as well but that's the one I've always used.

OK, so I figured out that Feed gets loaded because
it's referred to in a remoting destination in remoting-config.xml, and I got my
class running the same way.  However, I'm assuming this isn't the right
way/place to setup FlexSession listeners and implement push logic via
DataServiceTransaction.  Can you point me in the right direction? 

Thanks,

Tom

I'm new to J2EE webapps,
so please pardon my ignorance.  When does the Feed class get
loaded/instantiated?  Does this happen automatically when the samples
server is started?  I'm trying to do something similar in another app but
my class doesn't seem to be loading.  I dropped my class in {
server.root}/default/flex/WEB-INF/classes/test and was hoping it would
magically start running when I restarted the server.  My goal is to figure
out how to work with FlexSession and DataServiceTransaction and I figured I'd
be able to do that from the class below.  Any help getting it up and
running would be greatly appreciated. 

//in C:\JRun4\servers\default\flex\WEB-INF\classes\test
package test;

import flex.messaging.FlexSession;
import flex.messaging.FlexSessionListener;
import flex.data.DataServiceTransaction;

public class MyTest implements FlexSessionListener 
{
    private static FeedThread thread;
    
    public MyTest()
    {        
        thread = new FeedThread();
       
thread.start();        
       
FlexSession.addSessionCreatedListener(this); 
    }
    
    public void sessionCreated( FlexSession session )
    {
        System.out.println(
"sessionDestroyed!" );
    }        
    
    public void sessionDestroyed( FlexSession session ) 
    {
        System.out.println(
"sessionDestroyed!" );
    }
    
    public static class FeedThread extends Thread
    {
        public boolean running = true;

        public void run() 
        {
            while
(running)
            {
           
    /*
           
    DataServiceTransaction dtx = DataServiceTransaction.begin(
false );
           
    dtx.refreshFill( "myDest", new ArrayList() ); 
           
    */

           
    System.out.println( "running!" );
           
    
               
try
               
{
                   
Thread.sleep(1000);
               
}
               
catch (InterruptedException e)
               
{

               
}
            }
        }
    }    

}
