Tomcat JMX connection - Authentication failed.
I am having some problems setting up Tomcat for JMX. I added the following
properties to CATALINA_OPTS
CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=18070
-Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password
-Dcom.sun
.management.jmxremote.ssl=false"
And have added the jmxremote.password file in to the conf directory. I wrote
a client tool that connects to the JMX server running on port 18070. When i
run the client program i get the following error.
Exception in thread "main" java.lang.SecurityException: Authentication
failed! Credentials required

If i change the CATALINA_OPTS properties to
CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=18070
-Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password
-Dcom.sun
.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
Then it works fine. I think what i am confused of is what is classed as
remote access. I am running the client program away from the Tomcat instance
but both Tomcat and the client tool are on the same machine (i.e. different
virtual machines but same environemnt). I thought i had to configure the
remote authentication if i access the JMX server remotely from a different
machine.
By remote access do they mean accessing the JMX server from any VM either
locally on the same machine or remotely from a different machine?
