Did you install the IBM MQ resource adapter?
https://www.ibm.com/docs/en/ibm-mq/9.0?topic=adapter-installing-testing-resource-in-wildfly

[vamsi M]

Hello Mayer,

Yes , I deployed the adapter wmq.jmsra.rar .

As per your comment to test the the MQ installation , where can I find this ear file wmq.jmsra.ivt.ear to deploy and test my MQ setup ?

Thanks for the quick response .

Regards,

Vamsi

Hi, 

Log says that can't find jni lib. 

Double check is lib in any folder or add some additional folder into java.library.path if like to load lib from some other folder.

Hi Vesa,

I can see the library file in the server where the MQ is installed

/usr/mqm/java/lib/libmqjbnd.so

/usr/mqm/java/lib64/libmqjbnd.so

Do I need to have the same file in the server where my wildfly is installed ? 

Regards,

Vamsi Madduluru

[vamsi M]

Hi Vesa,

Tried placing the library file in the path /usr/lib where the wildfly is installed , Below is the error

Hi

Now it does found the lib but did you copy correct version? 

ELF is the abbreviation of 'Executable and Linkable Format' (http://flint.cs.yale.edu/cs422/doc/ELF_Format.pdf)

This is normally a problem with 32/64 jvm mismatch

Hi Vesa,

I copied the lib from the MQ server which my wildfly is trying to connect ,

I think the version is WMQ messaging : '7.5.0.6  as per the mq trace logs .

 Wildfly is configured to use client mode to communicate with MQ , as per the logs mqjbnd is used only for bindings mode connection . But still the K+JVM is trying to find the native library .

Below is message in the logs,

The native library 'mqjbnd' is used by the WebSphere MQ classes for

Java and WebSphere MQ classes for JMS when creating a connection to

the queue manager using a 'bindings' mode connection. A bindings

mode connection is a connection which uses the system's memory to

communicate with the queue manager, as opposed to a 'client' mode

connection which uses a TCP/IP socket.
