+/**
+ * A <CODE>BytesMessage</CODE> object is used to send a message containing a
+ * stream of uninterpreted bytes. It inherits from the <CODE>Message</CODE>
+ * interface and adds a bytes message body. The receiver of the message supplies
+ * the interpretation of the bytes.
+ * <P>
+ * The <CODE>BytesMessage</CODE> methods are based largely on those found in
+ * <CODE>java.io.DataInputStream</CODE> and
+ * <CODE>java.io.DataOutputStream</CODE>.
+ * <P>
+ * This message type is for client encoding of existing message formats. If
+ * possible, one of the other self-defining message types should be used
+ * instead.
+ * <P>
+ * Although the JMS API allows the use of message properties with byte messages,
+ * they are typically not used, since the inclusion of properties may affect the
+ * format.
+ * <P>
+ * The primitive types can be written explicitly using methods for each type.
+ * They may also be written generically as objects. For instance, a call to
+ * <CODE>BytesMessage.writeInt(6)</CODE> is equivalent to
+ * <CODE> BytesMessage.writeObject(new Integer(6))</CODE>. Both forms are
+ * provided, because the explicit form is convenient for static programming, and
+ * the object form is needed when types are not known at compile time.
+ * <P>
+ * When the message is first created, and when <CODE>clearBody</CODE> is
+ * called, the body of the message is in write-only mode. After the first call
+ * to <CODE>reset</CODE> has been made, the message body is in read-only mode.
+ * After a message has been sent, the client that sent it can retain and modify
+ * it without affecting the message that has been sent. The same message object
+ * can be sent multiple times. When a message has been received, the provider
+ * has called <CODE>reset</CODE> so that the message body is in read-only mode
+ * for the client.
+ * <P>
+ * If <CODE>clearBody</CODE> is called on a message in read-only mode, the
+ * message body is cleared and the message is in write-only mode.
+ * <P>
+ * If a client attempts to read a message in write-only mode, a
+ * <CODE>MessageNotReadableException</CODE> is thrown.
+ * <P>
+ * If a client attempts to write a message in read-only mode, a
+ * <CODE>MessageNotWriteableException</CODE> is thrown.
+ *
