title: Connecting to JMX server in spring throws exception!
body: <p>So when I try to connect to jmx from jconsole I get this exception:</p>
  
  <pre><code>Caused by: java.rmi.ConnectException: Connection refused to host: 78.84.17.116; nested exception is:

  <p>I was trying to connect to such url in jconsole: <code>service:jmx:rmi:///jndi/rmi://78.84.17.116:43030/test</code></p>
  
  <p>My jmx spring configuration:</p>

  <p>What could I be doing wrong that jconsole doesn't want to connect to this jmx server? And what does <code>test</code> in the end of jmx url mean? I just saw that it like that in a tutorial so I wrote the same in my url.</p>
  
  <p><strong>Edit 1:</strong>
  When I run <code>netstat -ntlp</code> on server I get this:
  tcp6       0      0 :::10099                :::*                    LISTEN      10754/java</p>
  
  <p>Where 10754 is the right java application. Is that correct? Running telnet <em>.</em>.*.* on 10099 I get a message that it connected to it too. So I guess it's not firewall on server side?</p>
  
  <p><strong>Edit 2:</strong>
  Okay well I'm trying now (and the exception bellow was thrown on server too) to run the app on my local environment (in Eclipse) and I guessing that it ain't server problem because all the same things happen.</p>

  <p>Could the problem be in configuration? Could someone verify that my configuration is correct?</p>
  
  <p><strong>Edit 3:</strong>
  I get this each time when I start the app. I guess that is the problem. It happens both on server and my machine..</p>
