Configuring MessageRequestor Services
MessageRequestor service will allow you to Synchronously do Request/Reply from a JMS Destination (Queue/Topic). You configure MessageRequestor services based on specific adapter connections. After you follow the steps in this section to configure the MessageRequestor service, you can invoke it from a flow or Java service. You use the MessageRequestor service in combination with other Adapter for JMS services that enable you to create JMS messages to add to the service's input signature and to convert JMS messages into documents that you can use within other services in Designer.
To use MessageRequestor services, you provide values for the service's input signature in the pipeline. For more information about using MessageRequestor services, see
Using MessageRequestor Services.
You can use the same configured MessageRequestor service to retrieve messages from multiple JMS Destinations, provided that the JMS Destinations are all available using the same adapter connection.
