JMS on demand poller

JMS OnDemand Poller

The JMS OnDemand Poller is a service, which is used to take messages on demand from a queue or topic (JMS destination).

You can choose to stop the processing of the flow or send a timeout-message further into the service chain if no message is found in the queue.

In the table below, you will find an explanation of these properties. All attributes with a ‘*’ are mandatory.

All attributes with a ‘**’, require exactly one of these properties having been set.

Attribute	Description
Name*	By default, we fill this out with the technical ‘tag’, followed by a serial number. Changing the name is optional.
Enabled	Set this value to true, if you want this service enabled at startup.
Destination**	This is the name of the Queue or Topic you want checked.
Destination Reference**	The reference to a Destination object. This is for topic support.
MessagePart Out	The name of the MessagePart, which will be used as output for the service method. On this MessagePart the message of the queue or the timeout-message is put before the message is sent to the other Services or the Producer. The default value is msgprt0.
Connection Factory	A Connection Factory determines which JMS environment is u,sed. By default, we’ll use a Connection Factory, which is incorporated as a Spring Bean with the name connectionFactory (connect.properties). If a different connectionFactory is desired, you may enter the name of another Connection Factory. This is a Spring Reference.
Receive Timeout	The time in milliseconds the Service waits before sending a timeout on the receive. By default this value is -1. This means the service does not wait.
Timeout Message	The text sent if no message has been found after the receive-timeout has expired. By default no message is sent.
