I have two application out of which one sends messages to a queue and the other listens to these messages.
My listener checks for a new message using receiveNoWait and sleeps for 2 min before checking again.
So in case my sender server is restarted and in the meantime, we are trying to access the queue, will my listener get any error?

You'd be a lot better off doing a receive with wait for 2 minutes, and not sleeping between calls.
Then for sure you will get an error thrown when/if the connection fails, you will process messages as soon as they arrive, rather than up to 2 minutes later, and you'll make much better use of your system processing and your MQ resources.

| My question was: In case I am trying to access a message from a queue whenever my sender's server is restarted, will I get an exception at Client's end? |

I answered that question. I also gave you a suggestion for how to improve your process - if your requirements do not force you to sleep for 2 minutes.
Have you looked at the documentation?
Have you tried unplugging a test machine from the network?
Yes, you will get an exception thrown when you attempt to use an invalid handle.
The Using Java manual or the Using C++ manual should be fairly explicit on that point.
