I am doing PoC on MQ. I have few doubts on Data conversion in MQ. I have gone through the manuals related to Websphere MQ application reference & guide. But I am not able to understand the below points.

1) in which scenario , we have to go for data conversion.

2) for which format of application data, we need to do data conversion exit program.

3) is the data conversion exit program is mandatory for mainframe cobol data items ?

It will be very greatfull, if you provide me the answers for the above doubts.

Note: I have put the message(COBOL DATA ITEM) in MQ and java is able to retrieve the message as it is. But, when i trying to get the message from java, i am getting as junk values.

There's no such thing as "junk values" in data. There may be values you don't understand, and there may be values the receiving computer doesn't understand, and there may be values that the transmitting computer doesn't understand -- but those values make sense to some computer along the way, whether or not they make sense to you. Post (useing the Code button to preserve spacing) some hexadecimal displays of what you consider "junk values" and we'll see what we can make of them.

show us the junk values in hex 100 bytes or so

it could be uTF8 or 16 or 32 since it is displayed by the pc ops-sys ok.
