I have a web application deployed to a remote resin server, and it has JMX turned on.
I can telnet to the remote server i.e
franz@see:/tmp$ telnet <remote-ip> 5555
Trying <remote-ip>...
Connected to <remote-ip>.
Escape character is '^]'.
��sr5javax.management.remote.message.HandshakeBeginMessage�,���6profilestLjava/lang/String;Lversionq~xppt1.0^]
telnet> q
Connection closed.
But I cannot connect to it using my JConsole
$JAVA_HOME/bin/java -cp $JAVA_HOME/lib/jconsole.jar:$JAVA_HOME/lib/tools.jar:pm-common/lib/jmxremote_optional-1_0_1_3.jar sun.tools.jconsole.JConsole service:jmx:jmxmp://<remote-ip>:5555
I have tried this with the following java versions but I get a 'Connection Failed' on both instances.
## where JAVA_HOME=/opt/java/64/jdk1.5.0_22
java version "1.5.0_22"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_22-b03, mixed mode)
## where JAVA_HOME=/opt/java/64/jdk1.6.0_17
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode)
Do you guys have any idea as to how to debug this (i.e. find out what's wrong)?
Make sure you are running your application with following java properties set
-Dcom.sun.management.jmxremote.port=9005
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
Try to connect now. If you want to debug this ,you can run the jconsole with following command
jconsole -J-Djava.util.logging.config.file=path_to_logging.properties_for_jconsole
Below is the content of logging.properties file
Logging.properties
handlers = java.util.logging.ConsoleHandler
.level = INFO
java.util.logging.ConsoleHandler.level = FINEST
java.util.logging.ConsoleHandler.formatter = \
java.util.logging.SimpleFormatter
// Use FINER or FINEST for javax.management.remote.level - FINEST is
// very verbose...
javax.management.level = FINEST
javax.management.remote.level = FINER
Once you run jconsole a separate window will pop up displaying logs.
