#16 Error connecting to SUN JDMK

[Anonymous]

Get an error in 1.2beta when trying to connect to Sun
JDMK RmiServer on a win2k dev machine. Using jmx1.2
(jmxri.jar, jmxtools.jar), also have jmx1.0 remoteing in
classpath (jmxremote.jar, jmxremote_optional.jar) and
jmx_remoting.jar (part of jdmk that has
RmiConnectorServer). Any idea what's work here?

This happens when there are incompatible versions of the JMX
classes on the server and the client. In this case, MC4J
includes sun's jmx 1.1 version.

You may be able to make this work by placing the jdmk jmx
jar into the "lib/ext" directory of mc4j. Then, you would need
to use the "bin/runide.exe" or "bin/runide.sh" scripts, but that
should override the classes included with mc4j.
