Hi, For monitoring purpose, I activate the JMX diagnostic feature in our Jasperserver 7.x. I do set with follow the Administratation Server Guideline for Jasperserver 7.x. Below is configuration But when I try to connect using check_jmx tool I got following messages I'm using username jasperadmin and password jasperadmin for authentication purpose. Can you suggest what configuration that I need to change? Thank you Bayu Permadi
