You could specify MessageHandler.NOOP in that case?

Hi All,
I want server and client both to handle multiple messages.
For example say AddMessage, SubtractMessage, AddResultMessage and
SubtractResultMessage.
When client sends AddMessage it receives AddResultMessage and similar for
SubtractMessage.
I am using mina 2.0M1.
According to my understanding I need to write message, encoder, decoder
and
handler classes for these messages.
As both the client and server should be able to handle different
messages, I
have extended from
DemuxingIOHandler for client and server main handlers.
I have added the encoders and decoders to DemuxingProtocolCodecFactory
and
added this to filter chain.
Now in these main handlers I need to add handlers for individual
messages.
So that is done by:
In server side handler
addReceivedMessageHandler(AddMessage.class, new AddMessageHandler());
addReceivedMessageHandler(SubtractMessage.class, new
SubtractMessageHandler());
addSentMessageHandler(AddResultMessage.class, new
AddResultMessageHandler());
addSentMessageHandler(SubtractResultMessage.class, new
SubtractResultMessageHandler());
But on server side I don't want to do anything in the
Add/SubtractResultMessageHandler's handleMessage() method.
So is there any way to avoid adding these handlers?
If I don't add these handler then it gives exception.
On the client side also I need to do same thing.
There I don't want to use the Add/Subtract message handler's
handleMessage()
method.
In general is there any way to avoid adding handlers for sent messages?
If not, then does that mean that I need to write different
messageHandlers
for client and server for the same messages?
Thanks in advance.
