[SNMP4J] Response null when Set value to SNMP agent

[micky]

Hi all,

 

I use SNMP4J 1.9.2 version.

 

I want to SET value to the SNMP device. I use a SET PDU with version 1 will
work and response the setting value.

 

But when I use a SET PDU with version 3, it will response null. (don't know
why)

 

 

I have verify the access permission of version 3 and it will be workable
when I use a GET PDU or GETNEXT PDU with version 3.

 

 

And I use other SNMP tools to try if my SNMP device goes wrong, but other
SNMP tools works well when SET with version 3.

 

So I think it may be that I ignore something important to write code in my
program?!

 

 

Any suggestion will be very appreciated.

 

 

Sincerely,

Micky
