Yes, of course you can use it.

What do you mean with "single thread of messages"? May be
I do understand your logging approach, but Log4J and Java logging
IMHO only makes sense when used with different logger
(=LogAdapter in SNMP4J) instances?

This class is only an example.

You cannot for the SnmpRequest class, but since this is only
an example, this should not make any trouble.
For any other implementation, you can use your own logging
factory.
