hi.......if you try to take a TruthValue using a MIB Browser , you receive nothing because org.jboss.jmx.adaptor.snmp.agent.RequestHandlerImpl doesn't manage booleans ....I added a patch into getValueFor method ( row 474 ) that manage it with good results. I think that setValue method doesn't need the same correction because joesnmp can simply to interpret TruthValue as SnmpStringOctet object

row 474:

else if (val instanceof Boolean)

{ Boolean in = (Boolean) val; ssy = new SnmpOctetString(in.toString().getBytes()); }
