Men,
My understanding is that the 13 native calls of MQ API (MQCONN, MQPUT...) are NOT supported in Java, but are supported through JMS. Is this understanding right or am I amiss ?? Level of doubt is basic, but will definitely help.

a) We're not all Men
b) You'll find what is and is not supported in Java by reading the Using Java manual.

Hello,
I am rephrasing what I understand..
WMQ provides WebSphere MQ classes for Java and WebSphere MQ classes for Java Message Service (JMS). Using either of these, a Java application will connect to a WebSphere MQ queue manager and access its resources. These classes provided by IBM internally implement the 13 MQ API calls. This is unlike in other programming languages like C, C++ or COBOL where we use the 13 MQ API calls directly.
I still ask is this understanding right ??

Yes

I don't know and provided they work I don't care.

This would be because Java is an object orientated language rather than a procedural one that uses function call. The same sort of objects are used in C++ for the same reason. As you'd know if you'd looked it up

Why are you asking? What are you driving at?

There are, generally, two styles of MQ APIs.
A procedural style, and an object oriented style.
C is a procedural style language.
C++ is an object oriented language.
Java is an object oriented language.
JMS is not an MQ API. JMS is a Java API, that can be used to talk to MQ.
Welcome to programming. Now you have to start learning how to think like a programmer.
