[SNMP4J] [Fwd: java.lang.IllegalArgumentException error]

[Frank Fock]

Hi,

The error is not where you guessed it was.
Instead the error message gives the reason.
You have to use a ScopedPDU for SNMPv3.
So instead

PDU request=new PDU();

you have to use

ScopedPDU request=new ScopedPDU();

That is all.

Best regards,
Frank
