Jboss Enabling JMX for SolarWinds

senthil.nathanm

Hi All

I am working on setting up JBoss 5.1 (Sun Java 1.6) for monitoring using SolarWinds for which I am having trouble enabling JMX.

I added the following lines to run.sh

JAVA_OPTS="${JAVA_OPTS:+$JAVA_OPTS -Dprogram.name=$PROGNAME}"

JAVA_OPTS="${JAVA_OPTS:--Dprogram.name=$PROGNAME}"

JAVA_OPTS="$JAVA_OPTS -Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl"

JAVA_OPTS="$JAVA_OPTS -Djboss.platform.mbeanserver "

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=8686"

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.authenticate=false "

Now the instance wont start and fails with class not found error.

I looked up @ various JBoss forums but no luck.

Your help/inputs will be much appreciated.

I fixed the problem and thought I'd post the resolution for it.

This error is a BUG in JBoss 5.1 which is now fixed in subsequent releases. To address the class not found error, perform the following steps

1. From $JBOSS_HOME/lib/jboss-system-jmx.jar extract the classes, org/jboss/system/server/jmx/MBeanServerBuilderImpl.class and org/jboss/system/server/jmx/LazyMBeanServer.class
2. Unpack $JBOSS_HOME/bin/run.jar
3. Add the above mentioned classes to run.jar exploded directory and pack it (You may have to create the directory org/jboss/system/server/jmx/)
4. Start JBoss using run.sh
