Not sure if this is the right place to post this question but I have a requirement to get our Mbean accessible via SNMP. I believe have the everything setup because I use a simple SNMP manager to get and set values for MBean with simple type. My problem is when I have MBeans with custom POJO data types in the setters and getters I receive the follow error in the JBoss console: [SnmpAgentService] Unknown type for [oid=.1.3.6.1.4.1.2162.500.2.1, mbean=messenger:service=HelloWorld, attr=Message, rw=true] I have a PropertiesEditor created and it wors via the JMX console for setting and getting the values with my custom data type but not in my SNMP Manager. I am using AdventNet MIB browser to test with. Again... It works when the MBean uses String, integers and other simple types but not with Class types.
