Windows Telnet and GPRS clients
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.

Message
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.

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...

If you're using HyperTerminal (hypertrm) you might want to check out the
ASCII Setup (File --> Properties --> Settings tab --> ASCII Setup. The
first two options may be what you're looking for.

Posted by Ahmed Al-Obaidy <ah...@yahoo.com>.
Thanks Eero...
I wrote a new ProtocolCodecFactory... very similar to TextLineCodecFactory...
the constructor became like this:
public RtuTextCodecFactory( Charset charset )
{
encoder = new TextLineEncoder( charset, new LineDelimiter("\r"));
decoder = new TextLineDecoder( charset, new LineDelimiter("\r") );
}
and its working now...
thanks alot

You can tell TextLineEncoder and TextLineDecoder to use any
LineDelimiter you need. TextLineCodecFactory just wraps these two up and
implements the ProtocolCodecFactory interface.

So what you are suggesting...
can I tell TextLineCodecFactory to use different LineDelimiter?? or should I write new codec from scratch??

Well the hexdump only shows the 'carriage return' character at the
end(CR 0x0D) so my guess is the textlinedecoder is still waiting for the
'line feed' character (LF 0x0A).

Well the hexdump only shows the 'carriage return' character at the
end(CR 0x0D) so my guess is the textlinedecoder is still waiting for the
'line feed' character (LF 0x0A).

IoServiceManager serviceManager = new IoServiceManager( acceptor );
serviceManager.startCollectingStats(1000);
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
try {
ObjectName name = new ObjectName("com.jels.kaddb.gateway:type=IoServiceManager");
mbs.registerMBean(serviceManager, name);
acceptor.bind( new InetSocketAddress(PORT), new ConnHandler(), cfg);
}
catch (Exception e) {
}
System.out.println("Tracking Gateway server started.");
}
public void sessionCreated(IoSession session) throws Exception {
System.out.println("Session created...");
}
}
I tired US_ASCII, ISO-8859-1 and UTF-8 for charset and same problem appeared ** I use mina-core-1.1.0.jar
Thanks in advance

Hi Ahmed,
Could you show us how you set up the server ?
Which ExecutorFilter and ProtocolCodecFilter you use, etc..
Thanks,
Maarten
