At best I'm an MQSeries neophite, so please be kind 
Working on a program that is going to send/receive messages to/from Websphere utilizating MQSeries. Was told today that it needs to work with both MQSeries "native" queues and MQSeries JMS queues. Since I've never heard of anything except MQSeries queue I'm at a loss. Are there different APIs? Or perhaps new functions added to the existing API? Any help would be appreciated. Sarcastic responses are also appreciated as I feel a fool having to ask something like this and hope someone is enjoying my befuddlement.

JMS is a different MQ API.
It talks to the same queues.
It sends and receives the same messages.
Except, by default, JMS will produce messages with an MQRFH2 header on them.
Now's a good time for you to read the WebSphere MQ "Using Java" manual.

Might be interesting. Since the program I'm working on is in ANSI C not Java. Do you know if there is a C API for the MQSeries JMS ? Better yet, where do I find it? Searching www.boulder.ibm.com now.

There is the XMS support pack that will give you the same API.
JMS can read messages that are produced by normal MQ API programs.
Normal MQ API programs can read messages that are produced by JMS, as long as they either expect to get an MQRFH2 or the JMS program (the queue destination, actually) doesn't add an MQRFH2.

Jeff,
Just want to make sure I completely understand this before I start on a four week coding effort.
My program can use the normal MQ API to converse with a Websphere program that is using MQ JMS API as long as we agree on whether or not to use MQRFH2 headers?
Thank you very much for your time and your effort.
