[SNMP4J] SNMP & JMX - Arrays

[david pocivalnik]

Hi Frank,

I realized that I have to add the MIB specification to the command in 
order to be able to retrieve table contents. Thus I downloaded the MIB 
spec for Java7 and executed

$ snmptable dp -v 2c -c public -m +JVM-MANAGEMENT-MIB -Os -Cw 70 -Ci 
1.3.6.1.4.1.42.2.145.3.163.1.1.4.20

but i always get

jvmRTInputArgsTable: No entries

but when I connect with JConsole I see three entries. The same is true 
for my simple MIB I created in order to map the tables/arrays of my MBeans.

am I missing something?
