Hi guys,
I'm using MINA to develop a GPRS gateway for an AVL system...
Now I'm using a very simple program for evaluation purpose ...
It just print messages come from TCP clients to the System.out
Tests works OK under Linux/telnet...
When I use it under Windows/Telnet I find a strange behavior showed up...
The telnet window doesn't echo my input... and the program output log each
character separately... but the IoHandlerAdapter still capture the messages
events....
the output seems like this:
Tracking Gateway server started.

ST:hi
Even more, when tracking devices connect the server... the messages appear in
the Log.. but the IoHandlerAdapter never catch the messages events...
the output look like this
Tracking Gateway server started.

here is my IoHandlerAdapter
import java.util.*;
import org.apache.mina.common.IoHandlerAdapter;
import org.apache.mina.common.IoSession;
import org.apache.mina.common.*;
import org.apache.mina.transport.socket.nio.*;
public class ConnHandler extends IoHandlerAdapter {
//private Map sessions=Collections.synchronizedMap(new HashMap());
public void exceptionCaught(IoSession session, Throwable t) throws
Exception {
t.printStackTrace();
session.close();
}
public void messageReceived(IoSession session, Object msg) throws Exception
{
System.out.println("Message");
String str = msg.toString();
//foreach (IoSession s in sessions.)
//session.write( "You said:" + str );
System.out.println("ST:"+str);
}
}
I think the problem has something to do with the charset... I tried many but no
success...
