If you get an error like this

[ERROR] ManagementContext - -Could not start the remote: JMX ConnectorServer <java.io.IOException: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: Exception creating connection to: localhost; nested exception is:

        java.net.SocketException: Invalid argument or cannot assign requested address]>java.io.IOException: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: Exception creating connection to: localhost; nested exception is:

        java.net.SocketException: Invalid argument or cannot assign requested address] 
        at mx4j.remote.resolver.rmi.RMIResolver.bindServer(RMIResolver.java:198)

Then its probably that you're on Java 1.4 and you have an existing process using the RMI naming server which clashes with mx4j.
