The camel-msmq component was only meant for working under Windows. So, you can only compile the native part of the Camel component only under a Windows box.

Hi

Tnx for your reply . But I did not found any things to fix that!

L.S.,

You would have to look for a JMS driver to access MSMQ, but I'm not sure there even is a platform-independent API available for accessing MSMQ. 

There are two possible solutions:

- Microsoft has a protocol for accessing MSMQ over HTTP called SRMP, which is an extension to standard web services technology.  You can probably look at the specs for this protocol and send out the correct XML message to MSMQ using camel-http.

- Another option is to install a little Fuse Mediation router application on your Windows server that has the MSMQ installed that can just copy messages to/from an FUSE Message Broker instance -- acting as a protocol bridge.

Regards,

Gert

I am trying to use camel-msmq v. 1.6.1.2 on Windows.  I am getting the following error:

smx@root:osgi> Exception in thread "SpringOsgiExtenderThread-72" java.lang.NoClassDefFoundError: Could not initialize class org.apache.camel.component.msmq.native_support.msmq_native_supportConstants

What library do I need, and how do I load it?

One approach that failed:  I put

    System.loadLibrary("JNIMSMQ.dll");

into a Bundle Activator.  This load call works from a standalone Java program, but causes a not-fully-logged failure in the OSGi bundle.

Thank you.

This component is @deprecated and removed in the 2.x line of Camel.

There are professional adapters for MS MQ you can use instead.
