Java EE (Java Enterprise Edition) General Discussion

Hi all.
I need some agent functionality of snmpv3 in our server. I found some free snmp stacks, but they all don't support snmpv3. Also i found one snmp agent snmpv3.jar. But i don't know who is the author and nothing else. So i don't have any support - no email, no web site :)))
May be some body used the agent. As i understand it can support all snmp version (1, 2, 3). I tried all, but when i use it with v3 (i use as manager Koshna SNMP MIB browser) i have troble, i have message in my err_out "Authentication is required for user testtest". I don't know waht it is and how to manage it. May be somebody used this libs and could explain me something.
By the way i should use only free software.

Thanx
