Dear Trustin,
You're exectly right. I've pointed source codes for imported JAR files of
MINA core. I've seen that getMessageTypes() methode is returning null, i
added messagetypes such as;
private static final Set TYPES;
static
{
Set types = new HashSet();
types.add( AcknowledgeMessage.class );
TYPES = Collections.unmodifiableSet( types );
}
public Set getMessageTypes()
{
return TYPES;
}
But, this time i'm searching why put methode is not filling the ByteBuffer
buff. Buff is sending to peer as all zeros. Maybe you have an advice.
Thanks for your interest have a good time.
Murat

Assuming that you are using the latest stable release of MINA (1.0.1)...
What do your MessageEncoder implementations return when getMessageTypes() is
invoked? It seems like one of your implementation is returning null.
Please let me know if I am correct.
