## org.apache.catalina.tribes
Class ByteMessage

    java.lang.Object
      org.apache.catalina.tribes.ByteMessage

All Implemented Interfaces:
  java.io.Externalizable, java.io.Serializable

    public class ByteMessage

extends java.lang.Object
implements java.io.Serializable, java.io.Externalizable

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.
