Frank,
I have that line in my code before I ever allocate an SNMP object and I'm still
getting the same failure. Below is a simplified version of my code:
private void initializeSNMP(boolean udp)
{
SNMP4JSettings.setExtensibilityEnabled(false);
if (udp)
transport = new DefaultUdpTransportMapping(new
UdpAddress(NetTools.getLocalIPAddress() + "/0"));
else{
TcpAddress address = new
TcpAddress(Inet4Address.getByName(NetTools.getLocalIPAddress()),1161);
transport = new DefaultTcpTransportMapping(address);
}
snmp = new Snmp(transport);
transport.listen();
}
private void myCallingFunction()
{
ResponseEvent event = null;
initializeSNMP(true);
snmpSettings.setSNMPPort(1161);
targetAddress = GenericAddress.parse("TCP:" +
snmpSettings.getAddress() + "/" + snmpSettings.getSNMPPort());
target = new CommunityTarget();
target.setCommunity(new
OctetString(snmpSettings.getCommunity()));
target.setAddress(targetAddress);
target.setRetries(snmpSettings.getRetries());
target.setTimeout(snmpSettings.getTimeout());
target.setVersion(SnmpConstants.version2c);
event = snmp.get(pdu, getTarget(snmpSettings));
}
When udp is set to true, the above works, when set to false it fails.

Hi Joe,
This issue seems to be caused by a class loader issue.
Please call
SNMP4JSettings.setExtensibilityEnabled(false);
Before you instantiate any address. That should solve the problem.
Best regards,
Frank
