JMSGateway
The JMSGateway class acts as a Java Messaging Service consumer or producer. The source for this event gateway is
located in gateway/src/examples/JMS. The gateway requires a configuration file, which is in
gateway/config/jmsgateway.cfg. For full documentation of the configuration options, See the configuration file. The
ColdFusion Administrator lists the compiled gateway (which is included in the gateway\lib\examples.jar file) on the
Gateway Types page.
Note: The ColdFusion Administrator uses JMS as the gateway type name for the JMSGateway class.
Using the JMS Gateway as a consumer
The JMSGateway class creates a subscriber to the topic specified in the configuration file. The gateway consumes the
following types of messages:
• TextMessage
• BytesMessage containing raw UTF-8 text
The gateway passes the contents of the message to the configured CFC in the event structure, as follows:
Field
Contents
data.id
Message correlation ID
data.msg
Text of the message
gatewayType
Gateway type: JMS
originatorID
Topic name from which the message was consumed
