[SNMP4J] 3DES trap is not sent

[NarayanaRao Yenduri]

Hi Team,
i 've problem in trap forwarding using 3DES protocol. 
i have copied the security policy jars already. the same code is working fine for all other protocols.

org.snmp4j.MessageException: Message processing model 3 returned error: Unsupported security level
at org.snmp4j.MessageDispatcherImpl.sendPdu(MessageDispatcherImpl.java:501)
at org.snmp4j.Snmp.sendMessage(Snmp.java:1004)
at org.snmp4j.Snmp.send(Snmp.java:885)
at org.snmp4j.Snmp.send(Snmp.java:878)
at org.snmp4j.Snmp.send(Snmp.java:843)

any quick suggestion to resolve this is appreciated.

Thanks
Narayanarao
