I am hoping this is the proper forum for my problem. I have enabled the
JmxRemoteLifeCycleListener and able to connect to tomcat 7 using
jconsole etc. using the following url.
service:jmx:rmi://10.92.12.88:10002/jndi/rmi://10.92.12.88:10001/jmxrmi
However as soon as I try to connect from my own application using the
code example below I get an error the following error. I figure I need
to configure the InitialContextFactory, but I don't know what class I
should specify. I also don't understand how jconsole is able to connect
without any additional configuration, but my client is not.
Perhaps somebody has some pointers on how to make remote JMX connections
programmatically.
