Microsoft Service Bus Connector 2.1 - Mule 4
Anypoint Connector for Microsoft Service Bus (Microsoft Service Bus Connector) enables message integration with Windows Service Bus on-premises. The connector supports communication with queues and topics through Advanced Message Queuing Protocol (AMQP) 1.0. In addition, dynamic discovery and provisioning of Service Bus objects is possible using the built-in management API.
This connector supports connecting only to the Microsoft Windows Service Bus on-premises solution. To connect to Microsoft Azure Service Bus, use Anypoint Connector for Azure Service Bus. |
Release Notes: Microsoft Service Bus Connector Release Notes
Exchange: Microsoft Service Bus Connector
Before You Begin
To use this information, you should be familiar with Microsoft Service Bus, Mule runtime engine (Mule), Anypoint Connectors, Anypoint Studio, Mule concepts, elements in a Mule flow, and Global Elements.
You need one of the following credential types to test your connection to your target resource:
-
Windows credentials type
-
SAS (shared access signature) - Deprecated
-
Username and password - Deprecated
For software requirements and compatibility information, see the Connector Release Notes.
To use this connector with Apache Maven, click the Dependency Snippets link in Anypoint Exchange.
The connector supports the Microsoft Windows Service Bus on-premises.
POM File Information
Replace x.x.x
with the version that corresponds to the connector you are using.
To obtain the most up-to-date pom.xml
file information, access the connector in Anypoint Exchange and click Dependency Snippets.
Add the Connector to a Studio Project
Anypoint Studio provides two ways to add the connector to your Studio project: from the Exchange button in the Studio taskbar or from the Mule Palette view.
Add the Connector Using Exchange
-
In Studio, create a Mule project.
-
Click the Exchange icon (X) in the upper-left of the Studio task bar.
-
In Exchange, click Login and supply your Anypoint Platform username and password.
-
In Exchange, search for "service bus".
-
Select the connector and click Add to project.
-
Follow the prompts to install the connector.
Get Queue List Use Case
This use case retrieves a list of existing queues in a specific namespace. It returns the list in JSON format.
-
Create a new Mule application in Studio and select HTTP Listener as a source in the new flow.
-
Add a new HTTP Listener configuration global element:
-
Specify the Host and Port parameters with the following values:
Parameter Value Host
0.0.0.0
Port
8081
-
Click Save.
-
Assign the new global configuration to HTTP Listener.
-
Complete the HTTP Listener path with the value
/servicebus
. -
Drag a new Service Bus component operation into the flow.
-
Configure the Service Bus connector global element with its environment values.
-
Add a transform message before the connector and add an output like this:
%dw 2.0 output application/json --- payload
-
Save and run the project as a Mule application.
To test the app, navigate to
http://127.0.0.1:8081/servicebus
.

Service Bus Authentication
For sending and receiving messages through the Service Bus connector, the authentication is performed through AMQP.
For the REST Management API, the authentication scheme differs based on the Microsoft Service Bus version. The Windows Service Bus uses OAuth.
The Windows Service Bus uses a self-signed SSL certificate to secure the communication via AMQP and HTTPS. The connector won’t run if this certificate is not locally imported in the box running Mule, unless the Ignore SSL warning check is enabled. |
To enable the SSL checks, the certificate must be imported following these steps:
-
Use the PowerShell cmdlet Get-SBAutoGeneratedCA to download the certificate locally in the box running the Windows Service Bus. For the purposes of this tutorial, assume the certificate file is exported to %temp%\AutoGeneratedCA.cer.
-
Go to %programfiles%\Java\jre7. Verify that the bin\keytool.exe tool exists, and that lib\security\cacerts exists. Note that you must be running as Administrator in order to perform a certificate import with Keytool.exe. Otherwise, an Access Denied error is generated.
-
Enter the following command: bin\keytool.exe –list –keystore lib\security\cacerts
-
Import the autogenerated Service Bus certificate by running the following command: bin\keytool.exe –importcert –alias AppServerGeneratedSBCA –file %temp%\AutoGeneratedCA.cer –keystore lib\security\cacerts –v
-
Enter the password when prompted (the default is “changeit”). If you do not know the password, you cannot perform the import. When the tool asks you whether to trust the certificate, enter Y (Yes).
Using Restricted Access Policies
In cases where you have restrict access to your resources, having a security policy with permissions just at resource level, the connector cannot perform the connectivity test
when it is starting up as this targets the root level of your namespace which might be forbidden due to the customized policy applied to the shared access key
. For these scenarios, you need to skip the connectivity test with the configuration option available to this purpose, otherwise connetor’s startup fails.
Log Requests and Responses
To log requests and responses when using the connector, configure a logger by adding this line to the Loggers
element of the log4j2.xml
configuration file for the Mule app:
<AsyncLogger name="org.springframework.web.client"
level="DEBUG"/>
The following example shows the Loggers
element with the AsyncLogger
line added:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<AsyncLogger name="org.springframework.web.client" level="DEBUG" additivity="false">
<appender-ref ref="Console" level="debug"/>
</AsyncLogger>
</Loggers>
</Configuration>
You can view the app log as follows:
-
If you’re running the app from the Anypoint Platform, the output is visible in the Anypoint Studio console window.
-
If you’re running the app using Mule from the command line, the app log is visible in your OS console.
Unless the log file path was customized in the app’s log file (log4j2.xml
), you can also view the app log in this default location:
MULE_HOME/logs/<app-name>.log
For more information about the app log, see Configuring Logging.

Troubleshooting
If the Mule app includes the Listener source, you might receive an error like this:
javax.jms.JMSException: The operation did not complete within the allocated time 00:00:14.9951934 for object connection
If you receive this error when starting the app or calling an operation, check whether the Service Bus server has the Redirect
feature enabled. If so, disable this feature by following the steps documented in the Known Issues section on this page: AMQP Java clients (and all non .NET clients) cannot send or receive to/from Service Bus.
