I looked connection ttl, and other parameters but nothing worked.

The connection failed after 10 seconds... Less than ping period, etc...

Code et my XML configuration can help you?

I already looked applet example.

My configuration :

Actions on in my Applet

params = new HashMap<String, Object>();

params.put("host", "XXX.XX.XXX.XX);

params.put("port", "8080");

params.put("use-servlet", true);

params.put("servlet-path", "/HornetQServlet/HornetQServlet");

factory =  HornetQClient.createClientSessionFactory(new TransportConfiguration(NettyConnectorFactory.class.getName(), params));

try {

    session = this.factory.createSession();

    //

I tested applet example but with servlet transport. When i send messages no problem.

But if i don't send message after a period of 15/20 seconds, i have this error :

"javax.jms.JMSException: HornetQException[errorCode=2 message=Channel disconnected]
