Salut,
My understanding is the client should also works but since you might
execute the read inside the CallbackHandler.onRead(..), it is up to you
to notify the listener. When you do:
>> try {
>> if(key.isValid() && key.isReadable()){
>> int count = socketChannel.read(response);
>> if(count>0){
>> response.flip();
>>
>> byte[] b = new byte[(int)count];
>> response.get(b);
>>
>> response.clear();
>>
>> System.out.println(new String(b));
>> }
>>
>> selectorHandler.register(key,
>> SelectionKey.OP_READ);
>> }
here you need to do if count == -1 or if an IOException is thrown:
((BaseSelectionKeyHandler)ctx.getSelectorHandler()).getSelectionKeyHandler().close(key);
A+
