Connectors provide an abstraction layer over data transport mechanisms. Connectors exist for things such as files, email messages, databases, JMS, and even Jabber messages. A connector saves you the tedium of having to implement the details of a particular communication mechanism yourself. This allows you to focus on solving your integration problem and not on the plumbing of a particular communications protocol.

JMS (Java Message Service) is a widely-used API for Message Oriented Middleware. It allows communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.

JMS supports two models for messaging:

Queues – Point-to-point

Topics – Publish and subscribe

Mule’s JMS transport lets you easily send and receive messages to queues and topics for any message service which implements the JMS specification.

In our example, we’d need an HTTP connector and a JMS connector. The HTTP connector would provide the message receiving infrastructure in the form of a dedicated listener on a particular port. The JMS connector would provide the capacity to connect to the target JMS provider (through its specific connection factory) and to handle the dispatch of messages to the desired queue.


Mule Studio 3.x(Anypoint Studio) (Download from
Maven 3.2.1 (Download from
JDK 1.7 (Download from
Active MQ 5.11.1 (Download from

Configure JDK, Maven and Mule Studio

Step 1. First install JDK
Step 2. Add the Java_Home/bin directory to your system’s PATH.
Step 3. After downloading Maven, extract it to a drive
Step 4. Add the M2_Home/bin directory to your system’s PATH.
Step 5. Download and extract Mule Studio to a drive
Step 6. Now start Mule Studio by clicking on AnypointStudio exe icon in the folder <physical drive>/AnypointStudio
Step 7. Once started, close the startup page
Step 8. In Mule Studio, go to Window -> Preferences. Expand Java, then click on Installed JREs. Add JDK 1.7 and select it. In expanded Java, click on Compiler and select the compiler level as 1.7
Step 9. Now expand Anypoint Studio and click on Maven Settings. Then select appropriate Maven installation home directory using Browse button.
Step 10. If you want you can input Default groupId for new projects, it will save your time every time when you want to create a new project.

Create Mule project in Mule Studio

Now we will see how to create a new project in Mule Studio(Anypoint Studio).

Step 1. In Anypoint Studio, go to File -> New -> Mule Project
Step 2. Input Project Name: mule-3, Runtime is by default selected, tick on Use Maven; here the artifactId is automatically picked up from the Project Name:, the Group Id is picked up from the Default groupId for new projects and version is also a default value.
Step 3. Click Next and verify the JDK, mainly select Use default JRE(currently ‘jdk1.7.0_x’)
Step 4. Click on Next and click on Finish.

So when the project mule-3 is created in the Anypoint Studio, the project structure looks like below

mule stdio

JMS Transport Example

The overall flow of the application is given below
mule jms transport with active mq

Step 1. You can rename the src/main/app/mule-3.xml file as mule-jms.xml file.
Step 2. Open the mule-jms.xml file and click on Configuration XML view in the Editor
Step 3. Create a Java class as shown here

Step 4. Modify the mule-jms.xml file as shown below

In the above XML Configuration, we first define activemq Connector with broker URl that is required to pass message to the JMS Queue.

Here we have inbound and outbound endpoints. The message is passed from inbound endpoint to outbound endpoint. Then the message is received by Java class method getMessage() and finally logged to the logger using Logger component.

Step 5. Add Active MQ dependency to the pom.xml file

Running the Active MQ

Extract the downloaded zip activemq in physical drive. Then open a command prompt and navigate to the <physical drive>\apache-activemq-5.11.1\bin and execute the command activemq start

Then open browser and hit the URL http://localhost:8161/admin and when prompted for username/password, type admin/admin and click on Queues. You will see that there is no message in the queue.

Running the application

Now do a right-click on the mule-jms.xml file or on the mule-3 project and click on Run As -> Mule Application. Then you will see something like below in Console when the application runs

Console output

Now hit the URL http://localhost:8081/Jms in the browser

mule jms transport with active mq

Now again click on the Queues in Active MQ web console, now you should see one message enqueued/dequeued from the Queue.
