Hello all -
We are running Tomcat 6 on RHEL 5 and Oracle JDK 1.6_24 and I am
having a problem loggin into the jmx services remotely through
jconsole.
Here is my setenv.sh :
JAVA_OPTS="-Xms512m -Xmx1152m -XX:MaxPermSize=512m"
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9888"
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
CATALINA_OPTS="$CATALINA_OPTS -Djava.rmi.server.hostname=192.168.33.70"
CATALINA_OPTS="$CATALINA_OPTS -Djava.rmi.server.logCalls=true"
Here is the output from 'ps -elf | grep tomcat' (I also see the 9888
port listening when using netstat) :
0 S root 2930 1 1 85 0 - 500084 184466 20:47 ?
00:00:15 /usr/java/default/bin/java
-Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties
-Xms512m -Xmx1152m -XX:MaxPermSize=512m
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-server -Dbuild.compiler.emacs=true -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9888
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Djava.rmi.server.hostname=192.168.XX.XX
-Djava.rmi.server.logCalls=true
-Djava.endorsed.dirs=/usr/local/tomcat/endorsed -classpath
/usr/local/tomcat/bin/bootstrap.jar -Dcatalina.base=/usr/local/tomcat
-Dcatalina.home=/usr/local/tomcat
-Djava.io.tmpdir=/usr/local/tomcat/temp
org.apache.catalina.startup.Bootstrap start
Then when trying to connect through jconsole I am running the
following command :
jconsole -debug 192.168.XX.XX:9888
It throws the following error:
java.lang.NullPointerException
at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:281)
at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:228)
at sun.tools.jconsole.ProxyClient.tryConnect(ProxyClient.java:334)
at sun.tools.jconsole.ProxyClient.connect(ProxyClient.java:296)
at sun.tools.jconsole.VMPanel$2.run(VMPanel.java:281)
I have run out of ideas for debugging this and can't seem to find any
answers. Any thought or ideas?
As a second problem, shutting down tomcat does not stop the jmx
process and i cannot restart tomcat since it is still listening on
9888. Do I have to specify anything to stop the JMX process during
shutdown?
Thanks all
