I just set this up and thought I should publish it someplace in case anyone else was interested.
When creating a MyEclipse Application Server configuration for Tomcat 5 make sure to specify JDK 1.5 as your JDK and include the following JVM arguments.
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9004
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
Start Tomcat 5 via MyEclipse and then use a JMX Console like MC4J [1] to connect. Be sure to use port 9004 when making the connection. I used the following Server URL to make the connection:
jmx:rmi:///jndi/rmi://localhost:9004/jmxrmi
