Jeff,
In my recent UDP agent release I set the community name with the
following code that seems to work okay. I believe I did a copy and
modify on the code of the most excellent SNMP4J test agent.
It's best to keep in mind when working with SNMP4J that V1 and V2C are
supported but in the context of V3. In particular many folks have had
problems with v2c notifications and I wrote a V2CNotifier class for the
UDP agent.

In the main routine of the SNMP agent I use this call ( after reading
the default context from the preferences ).
snmpDefaultContext = Activator.getDefault().getPreferenceStore()
.getString(PreferenceConstants.P_DEFAULT_CONTEXT);
if (snmpDefaultContext == null) {
snmpDefaultContext = Activator.getDefault().getPreferenceStore()
.getDefaultString(PreferenceConstants.P_DEFAULT_CONTEXT);
}
blah, blah, blah...
testAgent1.getServer().addContext(new OctetString(snmpDefaultContext));
I also use it in addCommunities where it seems to work okay:
protected void addCommunities(SnmpCommunityMIB communityMIB) {
Variable[] com2sec = new Variable[] { new
OctetString(snmpDefaultContext), // community
// name
new OctetString("cpublic"), // security name
getAgent().getContextEngineID(), // local engine ID
new OctetString(snmpDefaultContext), // default context name
new OctetString(), // transport tag
new Integer32(StorageType.nonVolatile), // storage type
new Integer32(RowStatus.active) // row status
};
MOTableRow row = communityMIB.getSnmpCommunityEntry().createRow(
new OctetString("public2public").toSubIndex(true), com2sec);
communityMIB.getSnmpCommunityEntry().addRow(row);
// snmpCommunityMIB.setSourceAddressFiltering(true);
/*
* CommunityTarget target = new CommunityTarget();
* target.setCommunity(new OctetString(snmpDefaultContext));
target.setAddress(new
* UdpAddress(trapDestination.toString() + "/" +
trapDestinationPort));
* target.setVersion(SnmpConstants.version2c);
*/
}
