Hi,
I'll try to describe more my issue.
I've implemented a class handler as below :
public class MyHandler extends IoHandlerAdapter
{
public MyHandler(){
//My constructor...
}
public void messageReceived(IoSession session_p, Object message_p)
{
System.out.println("A new message has been received - "+message_p);
...
//Here I have my business process
}
public void exceptionCaught(IoSession session_p, Throwable cause_p) throws
Exception
{
System.out.println("Caught exception - "+cause_p.getMessage(),
cause_p);
}
}
My client program sends the request to the server using the following code :
class MyClient{
NioSocketConnector myConnector = new NioSocketConnector();
handler = new MyHandler();
myConnector .setHandler(handler);
myConnector.getFilterChain().addLast("codec", new ProtocolCodecFilter(new
MyCodecFactory()));
// Start the connection
ConnectFuture conFutur = statusConnector.connect(new
InetSocketAddress(myRemoteServer,11001));
// Wait for the connection to be established
conFutur.awaitUninterruptibly();
//Send request
WriteFututre writer = mySession.write("MyMessage");
System.out.println("Connection established...");
//Wait few seconds
boolean isSent = writer.awaitUninterruptibly(10000, TimeUnit.MILLISECONDS);
System.out.println("Request sent...");
....
}
On the console I see that the following logs :
Connection established...
Request sent...
Caught exception - The connection was closed....
BUT my Handler doesn't display anything that means that it has been
called...
I have used a tool to see the data exchanged between my machine and the
server and I can see the the server has sent the response but the MINA
handler didn't get it !!
Can you help
Thanks
Hamid
