they still have this Jar in their libraries, but we don't know the purpose of this jar, as per below link, it looks like this jar is not being used.

This is why IBM Jar files should never be copied to application libraries.

The jar files should be referenced in the classpath from the <MQ Install>/java /lib directory and never be copied. So when you update your client you also update the libraries... and the app will take advantage of the new libraries.

Have fun

Hi fjb_saper, jar files can be referenced when there is an mq server or client installed locally, but what's the best practice when there's no client or server installed locally? Thanks for your time.

Thanks, exerk. I downloaded the redistributable client image and it contains com.ibm.mq.allclient and jms. Are these 2 files enough for JMS messaging?(I mean, Do these jars include the classes that come with mq client installation, like com.ibm.mqjms.jar, com.ibm.jms.*, com.ibm.mq.jms.*..) Thanks for your time.
