[SNMP4J] Snmp4j agent -- can print and store the incoming requests

[Frank Fock]

Hi Nitin,

Wha is your goal? Writing a SNMP agent?
Then you should use SNMP4J-Agent on top of SNMP4J.
Beginning writing a SNMP agent with SNMP4J from scratch needs a lot of SNMP know how.

SNMP4J-Agent already implements most of complex agent stuff. 

But finally, what is the printing for?

Best regards,
Frank
