[snmp] Problem: SNMP application with different versions.

[Birgit Arkesteijn]

Hi Vijay,

Your snippet of code seems fine.
Also, since you manage to send v1 and v2 traps, it seems that the 
implementation of SNMPClienV1 and SNMPClientV2 is fine.

The fact that the first item in the list determines what goes for the 
life of your application, indicates (to me) that the problem is within
SNMPFactory.getSNMPFactory(list.get(i));

I would try printing out
- list.get(i) and
- snmpcilent
to confirm my suspicion and take a closer look at 
SNMPFactory.getSNMPFactory().

Cheers, Birgit
