Aldo,

I instantiate it from a servlet that I've configured to load on startup via the following tags in C:\JRun4\servers\default\flex\WEB-INF\web.xml:

    <servlet>
        <servlet-name>AppStartServlet</servlet-name>
        <servlet-class>test.AppStartServlet</servlet-class>
        <load-on-startup>11</load-on-startup>
    </servlet>

which I placed at the end of the list of servlets just before the <servlet-mapping> section. I chose 11 so that it would be loaded after the last Flex servlet.

My AppStartServlet looks like this:

package test;

import javax.servlet.http.HttpServlet;

public class AppStartServlet extends HttpServlet
{
    private FlexSessionTest test;

    public void init()
    {

        test = new FlexSessionTest();
        System.out.println( "******************************* AppStartServlet loaded *******************");
    }
}

Then you should be good to go.

Hi tom,

looks like this might do it...
now, where/when exactly are you instantiating this FlexSessionTest object??

thanks,
Aldo

Aldo,

Here's some sample code that I used to know when a client disconnected. The FlexSession.sessionDestroyed event corresponds to a disconnection.

...
    public FlexSessionTest()
    {
        FlexSession.addSessionCreatedListener(this);
    }

    public void sessionCreated( FlexSession session )
    {
        session.addSessionDestroyedListener(this);
        System.out.println( "sessionCreated!" );
    }

    public void sessionDestroyed( FlexSession session )
    {
        System.out.println( "sessionDestroyed!" );
    }

HTH,

Tom

hi all,

I am building a java app that uses fds to pub/subs flex clients to a
set of jms topics and queues and I need a way to obtain a "connected
client list" on the java side... the traditional way would be to
create a topic to ping clients on a given interval.

alternatively, is there any fds low level message that indicates a
client disconnection??

Thanks,
Aldo
