Connecting to MSMQ¶
This section describes how to configure WSO2 Micro Integrator to connect with Microsoft Message Queuing (MSMQ).
The setup instruction here are only applicable for Windows environments since we invoke Microsoft C++ API for MSMQ via JNI invocations.
The msmq: component is a transport for working with MSMQ. This component natively sends and receives directly allocated ByteBuffer instances allowing access to the JNI layer without memory copying. Using the ByteBuffer created with the allocateDirect method, the native code can directly access the memory. URI format is msmq:msmqQueueName.
Follow the steps below to set up and configure WSO2 Micro Integrator with MSMQ.
- Download the axis2-transport-msmq-2.0.0-wso2v2.jar file and add it to the
MI_HOME/dropinsdirectory. This file provides the JNI invocation required by MSMQ bridging.
- Install Visual C++ 2008 (VC9). It works with Microsoft Visual Studio 2008 Express.
- Set up MSMQ on a Windows environment. For setup instructions, refer to: http://msdn.microsoft.com/en-us/library/aa967729.aspx.
- Download and install WSO2 Micro Integrator.
Setting up the JMS Listener and Sender¶
- Add the following configuration to
MI_HOME/conf/depployment.tomlfile to enable MSMQ listeners and senders.
[transport.msmq] listener.enable = true listener.hostname = "localhost" sender.enable = true
If you get an error message similar to the following when you start the Micro Integrator after configuring the JMS transport with MSMQ, you must check whether the
msvcr100d.dll file is available in the
C:\Windows\System32 directory. If the file is not available, you need to download the file and copy it to the
