Java – exception thrown when connecting to JMX server in spring!

• Java

So when I try to connect to JMX from jconsole, I get this exception:

Caused by: java.rmi.ConnectException: Connection refused to host: 78.84.17.116; nested exception is: 
    java.net.ConnectException: Connection timed out: connect
    at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:601)
    at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:198)
    ...

I tried to connect to such URL in jconsole: Service: JMX: RMI: / / / JNDI / RMI: / / 78.84 17.116：43030 / test

My JMX spring configuration:

What do I think is the error that jconsole doesn't want to connect to this JMX server? What does the JMX URL last test mean? I just saw it in the tutorial, so I wrote the same content in my website

Edit 1: when I run netstat - ntlp on the server, I get this: tcp6 0::: 10099:: * listen 10754 / Java

10754 is the correct Java application Is that right? Running telnet on 10099.. ** I received a message and it was connected to it So I guess this is not a server-side firewall?

Editor 2: Well, I'm trying (and throwing exceptions on the server) to run the application in my local environment (in eclipse). I guess it's not a server problem because all the same things happen

Is this problem possible in the configuration? Can someone verify that my configuration is correct?

Editor 3: I get this whenever I start an application I guess that's the problem It happens on the server and my machine

Solution

Try adding the following system properties to disable security:

-Dcom.sun.management.jmxremote.authenticate=false
 -Dcom.sun.management.jmxremote.ssl=false 
 -Dcom.sun.management.jmxremote.port=39600
