java - JMX password read access issue

Question

When I try to use JMX to monitor an application like this:

java -Dcom.sun.management.jmxremote.port=9999 
     -Dcom.sun.management.jmxremote.authenticate=false 
     -Dcom.sun.management.jmxremote.ssl=false 
     JMX_tester

it tells me:

Error: Password file read access must be restricted:
       /usr/lib/jvm/java-7-oracle/jre/lib/management/jmxremote.password

Yet, when I use chmod to restrict the read access, it tells me:

Error: can't read password file

Am I going insane or something? How can I fix this?

This is Ubuntu btw, with the latest oracle jdk

Answer 1

Make sure the user you are using to run the java process have access to the file (owner/read permissions).

Try:

chmod 600 jmxremote.password

Plus I suggest you'll make your own password file and run it with

-Dcom.sun.management.jmxremote.password.file=pwFilePath
