VuGen uses its API functions to implement the JMS transport. Each function begins with a jms prefix:
The JMS steps/functions are only available when manually creating scripts—you cannot record JMS messages sent between the client and server.
Unlike peer-to-peer communication that uses message queues, the publish-subscribe functions, jms_publish_message_topic, jms_subscribe_topic, and jms_receive_message_topic, are not supported for Web Service calls. To use these functions with Web Service calls, you must manually set up user handlers to generate the JMS message payload. For more information, see How to Create a User Handler.
For details about the JMS functions, see the Function Reference (Help > Function Reference or click F1 on the function).
