In my previous blog, i have demonstrated how to send message in the JMS queue using the OSB JMS adapter.

Now, we are gonna to extend this blog and show you how to get(pull) message from thhe JMS queue using the OSB JMS adapter.

After this blog, you should have learned to:

How to pull messages from the JMS queue and print the message in the logs

Let's see the step by step implementation.

1) Create a SB project
2) Create a schema with the below structure

JMS Pull

We have created structure as message will be in above format only.

3) Right click on the Left swim lane,Insert Adapters -> JMS


4) Enter name and click Next


5) Select Oracle Weblogic JMS from the drop down and click Next


6) Select the IntegratedWeblogicServer from the drop down and click Next -> Next

7) Select Consume Message radio button, as we need to pull message


8) Click Browse button and select the queue from where you want to pull the message. In our case it is TestQueue and leave all the fields as it is and click Next

9) Select Request element of the JMS.xsd schema and click Next

10) Click Next and Finish

Proxy service is ready now.

11) Insert a pipeline. 

12) Select JMS_PULL-concrete.wsdl using the browse WSDL option. Uncheck the Expose as a Proxy Service option and click Finish

13) Wire the JMS_PULL proxy service with Pipeline

14) Double click on the pipeline. Drag and drop the pipeline pair node. Drag and drop the log activity under the Request pipeline

15) Select the expression for the log activity

That's complete the flow. We are ready to test and see the messages in the logs

Let's put some messages in the TestQueue by running our previous business service

And see the the logs

You can directly put the message in the TestQueue from the weblogic console.
