Re: messageReceived() & dataRead() not called when Commons.TelnetClient sends messages

[Mohanbabu Narayanasamy]

I'm facing similar issue; When I use IoHandlerAdapter and print messages
from client, 
 
  ByteBuffer rb = ( ByteBuffer ) message;
       
        System.out.println("data received:" );
        
        while( rb.hasRemaining() )
        {
            System.out.print( ( char ) rb.get() );
        }
        System.out.flush();

it works fine. I tried the same logic with StreamIoHandler like this:
 
            BufferedReader in = new BufferedReader(
                    new InputStreamReader( this.in ) );
                
                String line;
                while ( ( line = in.readLine() ) != null &&
!line.equals( "" ) )
                {
                        System.out.println("data is:" + line);
                }

After the data is printed, there is an exception
 
java.io.IOException: Stream is closed.

I can't change the client to send new line or keep the connection open.
Any suggestions how to solve this?
 
thanks

Hi, 

Which decoder are you using? 

You can define your own protocol encoders and decoders which can handle
the data in whatever way you choose - you simply get a ByteBuffer which
you can decode.

I have resolved the problem: the TelnetClient did not append a new line
to 
the end of each write. I didn't realise that MINA IoHandler required a

newline in order to receive a line of data. I am curious as to how
other 
MINA users have resolved this when their incoming data did not include

newlines ('\n'), and they didn't have control over the client. Thanks
for 
your help.
