Connecting to a Websphere MQ in Java with SSL/Keystore

Question

I\'d like to connect to a Websphere 6.0 MQ via Java. I have already working code for a \"normal\" queue, but now I need to access a new queue which is SSL encrypted (keysto

Try this code along with T.Robs explanations about the certificate:
