About Service JMS rules

C-485 03-04 The JMS integration interface supports interactions between your PRPC application and other systems through the Java Message Service (JMS). PRPC supports JMS through both services and connectors. JMS services can receive (consume) messages from a JMS topic or queue and produce responses to those messages.
This facility supports both point-to-point and publish/subscribe messaging models. It supports durable subscriptions, automatic acknowledgment, and, if PRPC is deployed as an enterprise application, transaction-based processing.
To provide a JMS service, your PRPC system must be able to function as a JMS client. So if PRPC is deployed on a non-Java EE application server like Apache Tomcat, follow the vendor's documentation for that application server and configure the PRPC system as a JMS client. BURND 7/18/06
JMS services generally process service requests synchronously. That is, they immediately perform their requested processing and return a configured response while the calling application waits. However, you can configure JMS services to process service requests asynchronously, which means the service queues the request for asynchronous execution and the calling application calls back later for the results. Additionally, you can configure synchronous JMS services to check for specific error conditions that you expect will be temporary — work item locks, for example — and then queue service requests that fail for those reasons for another attempt at a later time.
Use the Application Explorer to see Service JMS rules in your application. Use the Records Explorer to list all Service JMS rules that are available to you.
For a description of the development process, see the following PDN articles:
Service JMS rules belong to the Integration-Services category. A Service JMS rule is an instance of the Rule-Service-JMS class.
