How to activate JMX on remote Glassfish server for access with jconsole?

java glassfish jmx jconsole

I would like to monitor remote glassfish server. I have enabled JMX Connection in domain.xml:

<jmx-connector accept-all="true" address="0.0.0.0" auth-realm-name="admin-realm" enabled="true" name="system" port="8686" protocol="rmi_jrmp" security-enabled="false">

But this didn't help. I still can't connect to server with JConsole. Then I've found solution - I need to specify JVM properties in domain.xml to open 8686 port for remote connection. So I added this lines into java-config section:

<jvm-options>-Dcom.sun.management.jmxremote</jvm-options>
<jvm-options>-Dcom.sun.management.jmxremote.port=8686</jvm-options>
<jvm-options>-Dcom.sun.management.jmxremote.local.only=false</jvm-options>
<jvm-options>-Dcom.sun.management.jmxremote.authenticate=false</jvm-options>

But now when I'm starting server, I'm getting following errors:

Could not load Logmanager "com.sun.enterprise.server.logging.ServerLogManager" java.lang.ClassNotFoundException: com.sun.enterprise.server.logging.ServerLogManager at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.util.logging.LogManager$1.run(LogManager.java:166) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.(LogManager.java:156) at java.util.logging.Logger.getLogger(Logger.java:273) at sun.management.snmp.util.MibLogger.(MibLogger.java:57) at sun.management.snmp.util.MibLogger.(MibLogger.java:42) at sun.management.jmxremote.ConnectorBootstrap.(ConnectorBootstrap.java:760) at sun.management.Agent.startAgent(Agent.java:127) at sun.management.Agent.startAgent(Agent.java:239) javax.management.JMRuntimeException: Failed to load MBeanServerBuilder class com.sun.enterprise.admin.server.core.jmx.AppServerMBeanServerBuilder: java.lang.ClassNotFoundException: com.sun.enterprise.admin.server.core.jmx.AppServerMBeanServerBuilder at javax.management.MBeanServerFactory.checkMBeanServerBuilder(MBeanServerFactory.java:480) at javax.management.MBeanServerFactory.getNewMBeanServerBuilder(MBeanServerFactory.java:511) at javax.management.MBeanServerFactory.newMBeanServer(MBeanServerFactory.java:298) at javax.management.MBeanServerFactory.createMBeanServer(MBeanServerFactory.java:213) at javax.management.MBeanServerFactory.createMBeanServer(MBeanServerFactory.java:174) at sun.management.ManagementFactory.createPlatformMBeanServer(ManagementFactory.java:302) at java.lang.management.ManagementFactory.getPlatformMBeanServer(ManagementFactory.java:504) at sun.management.jmxremote.ConnectorBootstrap.initialize(ConnectorBootstrap.java:392) at sun.management.Agent.startAgent(Agent.java:127) at sun.management.Agent.startAgent(Agent.java:239) Caused by: java.lang.ClassNotFoundException: com.sun.enterprise.admin.server.core.jmx.AppServerMBeanServerBuilder at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at javax.management.MBeanServerFactory.loadBuilderClass(MBeanServerFactory.java:423) at javax.management.MBeanServerFactory.checkMBeanServerBuilder(MBeanServerFactory.java:465) ... 9 more Exception thrown by the agent : javax.management.JMRuntimeException: Failed to load MBeanServerBuilder class com.sun.enterprise.admin.server.core.jmx.AppServerMBeanServerBuilder: java.lang.ClassNotFoundException: com.sun.enterprise.admin.server.core.jmx.AppServerMBeanServerBuilder

How can I fix the problem?

Thanks in advance.

Still mystical behavior, but with these 4 settings you can connect to the JVM running Glassfish (add to domain.xml in admin console, restart required)

-Djava.rmi.server.hostname=yourhost
-Dcom.sun.management.jmxremote.port=8686
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false

Beware ! This is not safe, as anyone now can connect a jconsole to it !

IMO this is not the Glassfish way, which is using the JMX connector.

(Above works in GF 3.1)
