How to use VisualVM and JMX?

Question

I have tried every recipe in the book, but things just wont work today...

I am trying to use VisualVM to profile my Java app running in a remote server, so I googled and googled and googled for ways to do this and I end up with this solution:

java -Dcom.sun.management.jmxremote \
  -Dcom.sun.management.jmxremote.port=9199 \
  -Dcom.sun.management.jmxremote.local.only=false \
  -Dcom.sun.management.jmxremote.authenticate=false \
  -Dcom.sun.management.jmxremote.ssl=false \
  -jar bin/felix.jar

Running this will get me JMX to run I guess, so I can see him running on 9199:

java      21947        root    9u  IPv6 1811434      0t0  TCP *:7192 (LISTEN)
java      26376        root   14u  IPv6 1844518      0t0  TCP *:9199 (LISTEN)

Moreover, I can test that the port is visible on the web:

Now, when I try to open the connection in VisualVM in my machine (which can also ping the jmx server) this happens:

I must be so dumb, that everyone in this world was able to put this thing running but me. Damn...

EDIT: I installed wireshark to know what's going on under the hood, so I saw this. As soon as I add a remote IP in VisualVM wireshark starts detecting this repetitive activity:

However, if I try to add a new JMX connection and ask him to connect, wireshark will not grab even one single packet of that connection attempt.

This seems to me that VisualVM is not even trying to connect, despite giving the error message "Cannot connect"...!! What the hell is going on?

Follow the below steps.
1) Go to remote machine open X11 forwarding,
2) Installed XMING in windows
3) Start visual VM in Remote machine the GUI will come in your windows xming.
4) Instead of IP use localhost and use same port number.

If above steps not working it means something is wrong with configuration.
If above steps working fine then go to iptables and ensure port 9199 open for outer world. as well start the program with java -Djava.rmi.server.hostname=YOUR_IP
