How does one determine the version of a jar file:
com.ibm.mqjms.jar no other context to determine its version
Is there a way to do it?
like 'strings com.ibm.mqjms.jar | grep {something useful}'
TIA

Open the jar with an (un-)zipper tool. Search and open the MANIFEST file.
Can be done with shell commands.

You determine the version of an MQ jar file by installing the client at a specific, known level.
Or by using dspmqver on the client install to tell what version the client is.
If you have a random MQ jar completely unrelated to an MQ client install, then you need to assume that it's a horrendously out dated version, and remove it, and then recofigure the application to use a full MQ client install. |

mqjeff is right, you should be aware of what you have deployed and of what you are doing... but... Java is Java and Jar-Files (always) have a Manifest-File: com.ibm.mqjms.jar\META-INF\MANIFEST.MF

And if you inherit an MQ installation without documentation, what's to be done?
Look at the manifest file.
Even with documentation, I would check the manifest file of an inherited installation.
Mr. Carey is a long-time participant on this forum. I doubt he needs a lecture on documentation. |

As I said, you replace it with a known version.
When complaints are made that this now requires extensive and expensive testing, agree that yes indeed proper documentation would have been cheaper.
And, yes, I agree, Mr Carey is a long standing member of this community who does not need lectures on proper documentation. That doesn't change my opinion of the correct solution for the problem at hand.
It's all well and good to continue to slap duct tape on a tyre to keep it from leaking air... but at some point, you are absolutely going to *have* to bite the bullet and buy new ones. And the *less* duct tape you have on your tires, the *less* risk you run during that sudden unexpected ice storm. |

It is all about the freedom (to choose what is the right approach for you).
Sometimes I would check all possible checks and then think about the (different  ) results this gave me. All possible checks are:
1. Docu, (if there)
2. display version command
3. Manifest file
@mqjeff: There is CSV (Computer Systems Validation). This can like "totally" disallow any change (to the runtime).

I found more then one time WAS installations with different com.ibm.mqjms.jar's . The deployed application includes these mq jar's . Of course this is not the correct way to tho things...
