[SNMP4J] Help me to send trap whith SNMP4J. Thanks

[Frank Fock]

Hi Peter,

The code looks OK for sending a trap. Here Snmp.listen()
is not needed. But note that you will never receive a
response on a trap.

Check with a sniffer like Ethereal whether the trap
looks OK on the wire or check with MIB Explorer (or
another trap receiver application) if you can receive
the trap with that.

Best regards,
Frank
