I want to get all message out of the queue and write to a file, i am using browsing option right now: openOptions = MQC.MQOO_BROWSE

so that i only get the first message out, how do i set a loop in my java program to recognize if it is the end of the queue.

when can i find the list of all the MQ options?

Thanks

You can find a list of all of the WMQ options by looking at the Application Programming Reference/Guide. The Using Java manual also has a lot of information in it.

As far as your actual program, you'll find quite a bit of sample code at:

My guess is that you don't want to browse the queue at all, but simply start getting the messages. There is a getGroup/putGroup pair of programs that should help you out. The messages are put/gotten based on a common group id.
