Hello,
It sounds like the OID is fine when using the
net-snmp tools, but the Java app is having problems?
If not, any more detail you can provide, like program
output would help. You say that you didn't get the
correct string. What did you get and what did you
expect?
Also,

I don't usually have spaces between the -c and -v
arguments, I seem to recall having problems when I had
spaces.
(.e.g. snmpget -cpublic -v2c localhost
.1.3.6.1.2.1.1.3.0)
