[SNMP4J] Emulation of snmp agent

[Lesya Oleynik]

Hi,
I'm a newbie in snmp4j agent library , but need to write small snmp agent
emulator as soon as possible. My agent need to recognize only 5 or 6 OIDs
and must send responses back to manager. First I tried to use SNMP4j
library(I implemented CommandResponder interface ) , but I'm not sure if it
is a right way to do so.
In snmp4j agent I cann't understand this points:
1. How to define my own MIB?
2. How to fill it with data?
3. How to retrieve data and send responses?

I understand that this questions may be obvious, but I ask your help.
THANKS!
