Hi all,

I have 2 problems

Problem 1 :

I am trying to write a MQ API Exit (MQReceiveExit) in Java for the following scenario.

Scenario:

Just for the accounting purpose, I want to move the message that iam going to GET from the queue to an temporary media.

My assumption is that, When ever the MQGET client program is run, the corresponding exist program that i have set in the MQGET program will be invoked. In the exit program I will be getting the application data also, which i will move to the temporary media.

but, whats happening is different. When i run the MQGet program, for each and every "MQCalls", the exit program is getting invoked. that is, for QManager connect, open, close, disconnect calls also, the exist program is getting invoked. I think, when ever there is some message from the queue manager (even for handshake messages), the exit program will be invoked.

But, I want the exit program to be invoked only for the "get()" call. Not for connect/open/close and disconnect. Inside the exit program, I want to retrive the actual message that is going to be read by the "get()" method from the queue.

Problem 2 :

The method signature in the exit program is

public byte []receiveExit(MQChannelExit channelExitParms,MQChannelDefinition channelDefinition,byte []agentBuffer){
// implimentation
}

Here, agentBuffer gives the byte array, This includes both MQ Message header and Data. ie, Iam getting some junk followed by the data. How to segrigate the application data alone from the complete MQ message.

Any help/suggestion/solution is greatly appreciated.

Thanks
