jboss could not load logmanager

问题

I'm trying to enable JMX on a JBoss AS 7.1.1 Final "Brontes". Sofar I edited the startup.conf in jboss/bin to hold these following lines:

# Enable JMX Remote
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9999"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.authenticate=false"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"

then on starting the jboss I got following error message:

> WARNING: Failed to load the specified log manager class
> org.jboss.logmanager.LogManager Exception in thread "main"
> java.lang.NoClassDefFoundError: org/jboss/logmanager/Level
>         at java.lang.Class.forName0(Native Method)

>         at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:120)
>         ... 4 more

Then I added following lines to the standalone.conf

JBOSS_MODULES_SYSTEM_PKGS="org.jboss.logmanager"

and

JAVA_OPTS="$JAVA_OPTS -Djava.util.logging.manager=org.jboss.logmanager.LogManager"
    JAVA_OPTS="$JAVA_OPTS -Xbootclasspath/p:$JBOSS_HOME/modules/org/jboss/logmanager/main/jboss-logmanager-1.2.2.GA.jar"

but still I'm getting the error

Now I'm out of ideas what to do next. I haven't found anything on google either. Can someone help me please?

For Wildly 14 you have to add Wildfly Commons and the Logmanager to the class path, hence the JAVA_OPTS looks like the following

-Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager 
-Djava.util.logging.manager=org.jboss.logmanager.LogManager 
-Xbootclasspath/p:/opt/jboss/wildfly/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.1.4.Final.jar 
-Xbootclasspath/p:/opt/jboss/wildfly/modules/system/layers/base/org/wildfly/common/main/wildfly-common-1.4.0.Final.jar 
-Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=127.0.0.1 
-Dcom.sun.management.jmxremote.port=10001 
-Dcom.sun.management.jmxremote.local.only=false 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false -Xms2g -Xmx2g -Xss512k 
-XX:SurvivorRatio=2 -Dsun.net.inetaddr.ttl=300 -Djava.net.preferIPv4Stack=true 
-agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n
