RMI stub for JMX in tomcat

Question

I am creating an RMI stub for JMX similar to the instructions in this blog post , and it opens a listening port as expected. When I try to connect to the port with JMX I get the following error:

java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.NameNotFoundException: jmxrmi
        at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:340)
        at javax.management.remote.JMXConnectorFactory.connect(JMXConnectorFactory.java:248)
        at ....

Is there any way for me to debug the RMI server and see why that name can't be found?

Thanks

Answer 1

Turns out that one of the configuration options was pointing to a file that didn't exist. JMX fell over silently :(

Answer 2

Looks like you left out a ':'. You should have service:jmx:rmi ...

Answer 3

The name of the connector is the last part of the URL (in the blog post it's "connector"). Change that to "jmxrmi".
