Consuming messages from a JMS queue

A message in a queue can only be consumed by a single consumer. To consume a message on the OSB, a proxy service with the JMS Transport needs to be setup.

In this recipe, we will show how to implement a proxy service as a message consumer for the queue. The proxy service will act as a listener on the JMS queue and will get active as soon as a message can be consumed from the queue.

Getting ready

For this recipe, we need one queue from the OSB Cookbook standard environment and will then implement the proxy service to dequeue the messages from the queue.

How to do it...

Let's create the proxy service to consume messages from the SourceQueue. In Eclipse OEPE, perform the following steps:

1. Create a new OSB project consuming-from-jms-queue and create a proxy folder within it.

2. Create a new proxy service and name it JMSConsumer.

3. Navigate to the General tab.

4. Set the Service Type option to Messaging Service.

5. Navigate to the Messaging tab

6. Set the Request Message Type option...
