Code Confuse: Oracle API Gateway: Enable embedded JMS in OAG

I was working on one of the requirement in which we have to communicate third party application using JMS queues. We are using oracle application gateway as a inbound/outbound interface so all the communication done through OAG, so in this case we are using JMS configured on oracle application gateway. Well in this blog post I am not going to describe my usecase but I will describe the basic step required to enable JMS in oracle application gateway (OAG).

Scenario:

I am going to enable jms in OAG first. I will create two queues incoming and outgoing. OSB application put the data on to incoming queue then jms listener in oag listen this incoming queue and put the data on outgoing queue. Well I am just showing here how to create a api gateway policy for jms communication so I am not going to tell how to configure your osb application to put the data on incoming (I hope you all know how to configure that).

Steps require to enable JMS in OAG:

Enable Embedded Active MQ on OAG
Create JMS Service External Connection in OAG
Create Queue in OAG Embedded Active MQ
Create OAG outgoing policy
Create JMS listener in OAG
Configure Embedded Active MQ jms connection on osb server
Test application

Enable Embedded Active MQ on OAG

Open policystudio --> go to server setting --> Messaging --> Embedded Active MQ -> configure as below

Check the box Enable Embedded Active MQ Broker
Active MQ connection details.

Address - localhost
Port: 62626
username: weblogic
password: welcome1

Apply changes.

Create JMS Service External Connection in OAG

Expand External Connection --> JMS Service --> Add a JMS Service
JMS service Connection Details

Name: Embedded OAG JMS Service
Provider url : tcp://localhost:62626
Initial Context Factory : org.apache.activemq.jndi.ActiveMQInitialContextFactory
Connection Factory : QueueConnectionFactory
Username : weblogic
Password : welcome1

Click Ok. Deploy your configurations.

Create Queue in OAG Embedded Active MQ

open url : https://localhost:8090 in browser
Go to Messaging --> Queues --> Actions --> Create Queue
create two queues i.e. InQueue and OutQueue.

Create OAG outgoing policy

Under policies --> create a policy container name "JMS Policies"
Create policy i.e. "OAG Outgoing"
Drag and drop messaging system from the Routing menu (from right panel)
Configure as below:

Click Ok to create a policy.

Create JMS listener in OAG

In the left panel under Listeners --> right click on Oracle API Gateway --> Messaging --> JMS Session, select the jms session you have created before

Add JMS consumer inside this JMS listener.

Click ok and deploy.

Configure Embedded Active MQ jms connection on osb server

This step is not require if you are not using osb application to test, you can configure other applicatoin to put the data on the incoming queue so that OAG Policy will work. Well my configurations is like below:
