Your application sends three messages with no delivery failures to a JMS destination,
where two consumers consume messages from the destination.

How do both consumers ensure they receive all messages?

Answer: Consumers subscribe to a JMS topic "with message selectors".

- Whats is the meaning of "message selectors" here?
- Could the answer be "JMS topic WITHOUT message selectors"?
Why not ?

Tks in advance!
