SAP interfaces throws an error message "Completion Code 2, Reason 2161, MQJMS2002”

As per my understanding, the only way to get the MQ jar files or the MQ C/C++ library files onto a system is by installing any of the below:

Using WebSphere MQ product or
Using WebSphere MQ Client SupportPacs

You can find jar file under WebSphere MQ V7.0 Clients SupportPacks. The install files are commonly available under java/lib directory.

You can try installing jar files from Fix Central. Go to Fix Central and enter "Java" in the Text search box.

~WebSphere%20MQ&query.release=9.0&query.platform=All

The name of the file to be downloaded is in this format:

<V.R.M.F>-[IBM|WS]-MQ-Install-Java-All.jar.

For example, for MQ V9.0:

9.0.0.0-IBM-MQ-Install-Java-All.jar.

You have the following files that can be moved to systems that need to run IBM MQ classes for Java applications:

- com.ibm.mq.allclient.jar

- com.ibm.mq.traceControl.jar

Installation Steps

To start the installation, you have to run the following command from the directory to which you downloaded the file.

You have to enter the directory to install the files to, or you can also press 'Enter' without entering any value to install to the default location as displayed. Once you have files installed to the requested location, you will get a confirmation message.
