 package org.apache.catalina.tribes;
A byte message is not serialized and deserialized by the channel instead it is sent as a byte array
By default Tribes uses java serialization when it receives an object to be sent over the wire. Java serialization is not the most efficient of serializing data, and Tribes might not even have access to the correct class loaders to deserialize the object properly.
The ByteMessage class is a class where the channel when it receives it will not attempt to perform serialization, instead it will simply stream the getMessage() bytes.
If you are using multiple applications on top of Tribes you should add some sort of header so that you can decide with the ChannelListener.accept() whether this message was intended for you.
 public class ByteMessage implements Externalizable {
Storage for the message to be sent
     private byte[] message;

Creates an empty byte message Constructor also for deserialization
     public ByteMessage() {

Creates a byte message wit h

data byte[] - the message contents
     public ByteMessage(byte[] data) {
          = data;

Returns the message contents of this byte message

byte[] - message contents, can be null
     public byte[] getMessage() {
         return ;

Sets the message contents of this byte message

message byte[]
     public void setMessage(byte[] message) {
         this. = message;

     public void readExternal(ObjectInput in ) throws IOException {
         int length = in.readInt();
          = new byte[length];

     public void writeExternal(ObjectOutput outthrows IOException {
         if ( !=null ) out.write(,0,.);
