Summary: Unable to connect from log4j2 Client GUI to my application
Key: LOG4J2-665
URL: https://issues.apache.org/jira/browse/LOG4J2-665
Project: Log4j 2
Issue Type: Bug
Components: JMX
Affects Versions: 2.0-rc1
Environment: OS: OSX Mavericks 10.9.3
IDE: Netbeans 8.0 (Build 201403101706)
Java: 1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08
log4j: 2.0rc1
Reporter: Arthur Hsieh
I am unable to connect from the log4j2 Client GUI, regardless of whether
running it as a JConsole Plug-in, or running it as a standalone application.
Below are details of what I've used in my attempts:
My application
- ran from Netbeans, with these VM arguments:
-Djava.security.policy=~/Downloads/policy -Djavax.management.builder.initial=
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
- I've tried various ports: 9010, 1099, 33445 etc
- Content of my policy file (I've allowed everything):
grant {
permission java.security.AllPermission;
};
Running the Client GUI as a JConsole Plug-in
- command I used to execute:
jconsole -pluginpath
~/Downloads/Software/Development/Java/log4j/2.0/rc1/apache-log4j-2.0-rc1-bin/log4j-core-2.0-rc1.jar:~/Downloads/Software/Development/Java/log4j/2.0/rc1/apache-log4j-2.0-rc1-bin/log4j-jmx-gui-2.0-rc1.jar
- The JConsole starts without issue, but I don't see the Log4j2 tab as per the
manual (http://logging.apache.org/log4j/2.x/manual/jmx.html)
Running the Client GUI as a Stand-alone Application
- command I used to execute (I'm running this from the directory where the JARs
are:
java -cp log4j-core-2.0-rc1.jar:log4j-jmx-gui-2.0-rc1.jar
org.apache.logging.log4j.jmx.gui.ClientGUI localhost:9010
- however, i getting a java.lang.NoClassDefFoundError:
