[SNMP4J] Newbie problem trying AgentJMX with error

[Wong, Noichi]

Hi all,

 

My environment

-Windows XP

-JDK 1.5.0_16

-Tomcat 5.5.27 

set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=2345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false

set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.snmp.acl=true
-Dcom.sun.management.snmp.interface=127.0.0.1
-Dcom.sun.management.snmp.port=1666

-Net-SNMP 

All I have in my C:\net-snmp\etc\snmp\snmpd.conf is "rocommunity public"
and I start NET-SNMP with c:\snmpd.exe

 

In JMXTestAgent.java main(), I have 'address = "127.0.0.1/161";'

and in addNotificationTargets mtehod, I tried changing
UdpAddress("127.0.0.1/162") to UdpAddress("127.0.0.1/1666") but no luck.

 

I am getting this error when I run JMXTestAgent.java

Jun 17, 2009 12:13:50 PM org.snmp4j.log.JavaLogAdapter log

SEVERE: java.lang.reflect.InvocationTargetException

Exception in thread "main" java.lang.NullPointerException

org.snmp4j.agent.mo.jmx.example.JMXTestAgent.main(JMXTestAgent.java:267)

 

Any help would be greatly appreciated.

 

Ultimately, if I run 'c:\ snmpwalk -On -v 2c -c public 127.0.0.1' I
should see information from my Tomcat's JVM, correct?

 

Thanks in advance.

 

Regards,
