[SNMP4J] Asynchronous Messages

[Frank Fock]

Hi,

You followed and incorrect example.
Do not send a message with any
MessageDispatcher if you do not know
what you are doing!

And do not start with a
MultiThreadedMessageDispatcher. for
most usages it provides no advantages.

Just use the Snmp class to send your
PDUs.

Best regards,
Frank
