Hi, I am attempting to use the Java 5 JMX server with James. I've followed
the instructions found on the ConfigureJmx page, but to no avail. It fails
at startup time with a NullPointerException when exporting the Embeddor. I
am using a freshly downloaded 2.3 James install with tweaks made to the
kernel.xml file based on the instructions in the wiki. I have also set the
PHOENIX_JVM_OPTS variable (since I am on Windows at the moment) to configure
the JVM's JMX settings. The value I've set is:
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=10201
Here is my component definition from the kernel.xml for the SystemManager:
<component role="org.apache.avalon.phoenix.interfaces.SystemManager"
class="org.apache.avalon.phoenix.components.manager.HostedSystemManager"
logger="manager" >
And finally, here is the error message I'm getting:
There was an uncaught exception:
