I recently had trouble connecting to a JMX server running on Linux (not EC2 though). It
worked after I specified a "java.rmi.server.hostname"
The parameters I used on the server side in the end were:
-Djava.rmi.server.hostname=192.168.0.25 -Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=22222
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
Maybe that'll fix it for you too.
We once had a server which was moved from our local office network
to a data center, during the move the network interface was re-configured
and that caused later issues with JMX.
Because somehow the following item was added to its hosts file:
127.0.0.2 SERVERX.xxx.net SERVERX
JMX tried to look up the ip address for its host name, and that was
then resolved to 127.0.0.2.
After removing the line it worked.
Setting java.rmi.server.hostname property can help to identify such
problems, or just get it working.
