The Java Message Service (JMS) API provides messaging capabilities to Java applications. In addition to exchanging messages among QAnywhere client applications, you can exchange messages with external messaging systems that support a JMS interface. You do this using a specially configured client known as a connector. In a QAnywhere application, the external messaging system is set up to act like a QAnywhere client. It has its own address and configuration.
For more information about the architecture of this approach, see Scenario for messaging with external messaging systems.
