Now I configured snmp-adaptor of jboss community to get/send snmp trap. I modified the ReadCommunity attribute of jboss-service.xml. That is I set the password to get/send trap. And I found the new ReadCommunity really works. I will get snmp trap only when I used the new ReadCommunity to query.
But when I capture the packet send between snmp client and snmp agent, it is surprising the ReadCommunity is not conformed. For example, if I set the ReadCommunity as "snmptest" in jboss-service.xml, and I can get snmp trap only when I use ReadCommunity as "snmptest", that is good.
But the packet send between snmp client and snmp agent is as list:
snmpget -c snmptest -v 1 -d 135.252.167.141:1161 .1.3.6.1.4.1.9.8.0

As the above packet, the packet send is "snmptest", but the packet received is "public". Could any body tell me the reason why the packet received is not "snmptest"?
