copied!<p>it seams that your ending quote comes too early. It should be after the last parameter.</p> <p>This trick worked for me.</p> <p>I noticed something interesting: when I start my application using the following command line:</p> <pre><code>java -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false </code></pre> <p>If I try to connect to this port from a remote machine using jconsole, the TCP connection succeeds, some data is exchanged between remote jconsole and local jmx agent where my MBean is deployed, and then, jconsole displays a connect error message. I performed a wireshark capture, and it shows data exchange coming from both agent and jconsole.</p> <p>Thus, this is not a network issue, if I perform a netstat -an with or without java.rmi.server.hostname system property, I have the following bindings:</p> <pre><code> TCP 0.0.0.0:9999 0.0.0.0:0 LISTENING TCP [::]:9999 [::]:0 LISTENING </code></pre> <p>It means that in both cases the socket created on port 9999 accepts connections from any host on any address.</p> <p>I think the content of this system property is used somewhere at connection and compared with the actual IP address used by agent to communicate with jconsole. And if those address do not match, connection fails.</p> <p>I did not have this problem while connecting from the same host using jconsole, only from real physical remote hosts. So, I suppose that this check is done only when connection is coming from the "outside".</p>
