Connecting to JMX server in spring throws exception!

Question

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 was trying to connect to such url in jconsole: service:jmx:rmi:///jndi/rmi://78.84.17.116:43030/test

My jmx spring configuration:

What could I be doing wrong that jconsole doesn't want to connect to this jmx server? And what does test 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.

Edit 1: When I run netstat -ntlp on server I get this: tcp6 0 0 :::10099 :::* LISTEN 10754/java

Where 10754 is the right java application. Is that correct? Running telnet ..*.* on 10099 I get a message that it connected to it too. So I guess it's not firewall on server side?

Edit 2: 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.

Could the problem be in configuration? Could someone verify that my configuration is correct?

Edit 3: I get this each time when I start the app. I guess that is the problem. It happens both on server and my machine..

I have no experience with JMX at all but it smells like a Firewall. — Erhan Bagdemir, May 11 '11 at 13:03
yeah firewall or the service is not up, as the 'Connection is refused'. — asgs, May 11 '11 at 13:05
@erhan, hmm, what should i do if it's server firewall? i'm a little blind on firewalls. — Rihards, May 11 '11 at 13:07
if you use tomcat as container, i remember that there was a jmx.port config in somewhere in catalina.properties. You have to allow incomming/outgoing comminication over the jmx port. — Erhan Bagdemir, May 11 '11 at 13:12
@erhan, umm well this is not a web app at all so I don't use any tomcat or jetty server for it.. but for the webapps i use jetty. — Rihards, May 11 '11 at 13:15
whatever you develops, you could still watch using some tools (on Windows exp. Zonealarm) outgoing traffic, or even with Wireshark on which port the request is delivered. — Erhan Bagdemir, May 11 '11 at 13:21

Try to add 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

Yep. You should add them to command line (if your are running from a command line) or to some kind of JAVA_OPTS if you are running server – Tarlog May 11 '11 at 15:16
@tarlog, so did as you said and I get this exception: `Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverConnector' defined in class path resource [META-INF/hw-common-jmx.xml]: Invocation of init method failed; nested exception is java.io.IOException: Cannot bind to URL [rmi://localhost:39600/myconnector]: javax.naming.NoPermissionException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.AccessException: Cannot modify this registry]` Need stack trace? – Rihards May 11 '11 at 15:20
Any idea what does the access exceptions mean? – Rihards May 11 '11 at 15:38
do you run with SecurityManager? – Tarlog May 11 '11 at 17:21
@Tarlog, added stack trace (and one question to main post) for the exception what is thrown when I run the app with system properties you provided. (I just changed the port to 43030 in -Dcom.sun.management.jmxremote.port) – Rihards May 11 '11 at 19:09
@Tarlog, by the way, when not running my app with these params so the exception is not thrown on my local machine I tried opening jconsole and select the app by process id and it worked out like a charm. However accessing it with the url didn't work.. – Rihards May 11 '11 at 19:11
@Tarlog, can you check if my service url is correct? I really don't understand why there has to be localhost and my ip in it and a /test in the end. What should the remote url I enter in jconsole to connect look like? – Rihards May 11 '11 at 19:12
@Tarlog, I doubt I run with any securityManager. Haven't seen anything like that in my app. – Rihards May 11 '11 at 19:13
See if this thread helps: http://forum.springsource.org/archive/index.php/t-26140.html – Tarlog May 12 '11 at 06:48
I had the com.sun.management.jmxremote properties mentioned set - but still got the AccessException - I then replaced my use of the RmiRegistryFactoryBean in Spring with a call to LocateRegistry.createRegistry(jmxPort) - and I could register my mbeans without getting exceptions. The problem only occurred for me when running my war inside an embedded Jetty (for integrationtest). When I deployed my war in other app servers I was allowed to register my mbeans. It seems like Jetty (9) auto creates a remote rmiregistry on the com.sun.management.jmxremote.port but with other security settings – joensson Aug 07 '14 at 14:01

The correct answer is to set alwaysCreate on your RMI bean like so:

    <bean id="rmiRegistry" class="org.springframework.remoting.rmi.RmiRegistryFactoryBean">
        <property name="alwaysCreate" value="true" />
    </bean>

This prevents the bean from attempting a connection to find an existing RMI registry.

That was not enough in my case (Spring 3.2.5). I had to stop using the RmiRegistryFactoryBean and use registry = LocateRegistry.createRegistry(jmxPort); before I was allowed to register anything. – joensson Aug 07 '14 at 13:55
