ChannelBuffer and messageReceived

[nixter]

Hello,

I have a writed a client/server program.

The client send data assembled in ChannelBuffer, the data look like this :

Sender, receiver, tag, DATA

Where sender, receiver, tag are integer and datas are a set of bytes.

the client send data like this :

channel.write(ChannelBuffers.wrappedBuffer(buffer)); where buffer is a
BufferByte.

In server side,  to gather datas I do like this :

public synchronized void messageReceived(ChannelHandlerContext ctx,
MessageEvent e) {
    	 
    	ByteBuffer buff = null;
       	 
        ChannelBuffer chanbuf = (ChannelBuffer) e.getMessage(); 

        buff=chanbuf.toByteBuffer();
    	 
    	int src=buff.getInt();
	int dest=buff.getInt();
	int tag=buff.getInt();
	
        ...
}

The problème is for small buffer i got the correct data, but for some buffer
i receive wrong data!! I know because communication are non-bloquant. 

My question is :  when netty call messageReceived () is the  ChannelBuffer
contains the whole data? 	
is there a mecansime like ByteBuffer.hasremaining to read the whole data
sent?

Please help if you have an idea or an example.

P.S sorry for my English
