Less than a minute on Google gave me:
Quote:
Integer.parseInt(x) converts String to int

Cheers,

Then your string is not a number.

This is not an MQSeries Java/JMS question.

I have stumbled against a similar scenario where a byte array contained a binary number.

Iterate through your array and write out each byte as hex (check out the byte methods). Then you can use Integer.decode method. Depending on your operating system you may have to reverse the order in the array(least significant/most significant) bit.

I used such a technique to decode the reason code from the dead letter queue header in java

Hope it helps
F.J.
