MQ Explorer allows you to administer and monitor IBM® MQ objects, whether they are hosted on your local computer or on a remote system. It can remotely connect to queue managers that are using an in-service version of IBM MQ on any supported platform including z/OS®, enabling your entire messaging backbone to be viewed, explored, and altered.
MQ Explorer is free to install, support is available to licensed IBM MQ customers - see the license agreement for details. For operating systems where this Eclipse plugin is supported by IBM see the MQ Explorer section of the IBM MQ 9.3 system requirements. In addition, this plugin may be used unsupported on macOS for development purposes.
Installation notes: If you get installation errors mentioning the "org.eclipse.draw2d" plugin, please install Eclipse GEF first from the Eclipse update site.

Works great on Eclipse 2022-12 but JMS Administered Objects wizard never launches to add an inital context. Anyone figured out a way to make this work?

Are you seeing an error with the JMS Administered Objects wizard.
Either way, have you tried to start Eclipse from the command line, to capture the related error message?

I can successfully install MQ Explorer by following the procedure to "Install software" within Eclipse; however, the Drag and Install method does not work, and produces an error that says the Plug in is not compatible with the version of Eclipse -- even though it is (and as I said will install successfully following the procedure).

I'm on my macOS Big Sur + Eclipse IDE for Enterprise Java Developers v 2020-03 (4.15.0) + IBM MQ Explorer 9.2.0 installed as IBM suggested on its page "Writing and running MQ applications on your Mac"
The MQ Explorer is working good but I can't save the passwords necessary to connect to my MQ Managers.
When I'm going to save passwords on the Passwords Preferences Page I get the message "An error has occurred. See error log for more details. com/ibm/misc/BASE64Encoder"
Can you suggest to me what should I do so that MQ Explorer would be able to save my passwords?
I appreciate any help to solve the problem.
Thank You In Advance

I suspect that this is because the MQ Explorer requires classes that are bundled only in an IBM JRE to encrypt the passwords. Unfortunately the IBM JRE isn't available for MacOS.
One way to tell would be to start MQExplorer from the command line. For me this is from the directory
Start MQ Explorer by running
This will capture the logs to the terminal. When you get the error you should see an error stack. I suspect it will be attempting to load something like

I am getting the same problem.
In the log it is looking for the class "com.ibm.misc.BASE64Encoder "
Is there anyway to get the class for MacOS?

I'm on MacOS - I'm following along this guide:
Writing and running MQ applications on your Mac
Developing with the IBM MQ MacOS Toolkit
I get everything setup, I'm using AzulJDK 11, but when I try to install it, that's the error I get.
I started at 4.15.0 and then went down to 4.14.0 hoping it would help, it didn't.
Any help would be appreciated! I just need the MQ Explorer tool so if there's a way to just do that, please let me know. So far I just saw that article as the only IBM approved method for MacOS.
Thanks in advance!

MacOS 10.15.7 (Catalina)
openjdk version "15.0.2" (Installed and managed by sdkman)
and MQ Explorer is working on Eclipse 4.15 and 4.19 (latest)
although I do get warnings on install that the plug-ins jars are unsigned
For 4.19, I installed Eclipse IDE for Java Developers (MacOS) from this page - https://www.eclipse.org/downloads/packages/
For 4.15, I installed Eclipse IDE for Java Developers (MAcOS from this page - https://www.eclipse.org/downloads/packages/release/2020-03/r
Can you confirm that they are the Eclipse packages that you have?

That's correct, we list the supposed versions in the marketplace description above and the latest working level is 4.15.
Submitted by Dennis Kuhlmeier on Wed, 2019-06-19 05:28
I am unable to figure out how to actually use this, even if unsupported, on macOS. On drag&drop the marketplace window opens, but the install doesn't start. It doesn't obviously fail either. So how can I test it?
Submitted by Ben Durrans on Fri, 2019-06-28 06:05
At the moment MacOS is not officially supported, but if you would like to use it for development purposes then I would recommend you check out the "Getting started with the IBM MQ MacOS Toolkit for developers" page on LearnMQ, where there is a section on how to install MQ Explorer.
Hope this helps,

on Mac if trying to install on top of Eclipse 4.8 then it says it's not compatible and don't want to install
and the link to download 4.7 for Mac don't work at this moment, unfortunately, so I can't try it
on the more modern Eclipse it also don't want to be installed. May this be this some limitation of JVM used? I'm trying with JDK 12
sorry, I understand the plugin is not supported on Mac, but..
Submitted by Dennis Kuhlmeier on Fri, 2019-08-16 09:04
Sadly I think 4.7 is required. Download link just worked for me, have you tried to select a different mirror? "Main Download Site" worked fine.

MQ Explorer plugin has been successfully installed, but I can only see how many messages are in queue. When I right clicked on the queue, I don't see the "browse" option as it appears in standalone "MQ Explorer". How do I browse queue message to exam message content in this plugin?
