Sending a string using a protocol buffer message

Question

How to send string as protocol buffer message? I want to do the following:

Message message1 = "some string"
ByteString data1 = (message1).toByteString();
System.out.println(String.format("Publishing [%s] on subject [%s]", message1, subject));
streamHandler1.publish(subject, data1);

Answer 1

You can use protocol buffer to serialize your object into a byte array.

Then, send the byte array to a Solace appliance/VMR as part of a BytesMessage

There's a simple example of how to send a message at the Solace website. Note that the example makes use of TextMessage, but can be easily replaced with BytesMessage.

In sequence:

1. Connect to the Solace Message Router
2. Create a producer
3. Create the BytesMessage object
4. Serialize your protocol buffer into a byte array
5. Attach the byte array to the previously created BytesMessage
6. Send the message
