[SNMP4J] TransportMapping error

[Frank Fock]

Hi Rick,

This could be caused by a simple classpath issue
or by an unsigned applet. Because the transport
mapping is using network ports, it requires
some privileges which are only available to
the applet, if it has been signed.

Hope this helps.

Best regards,
Frank

Any help would be great.  I have spent quite awhile on this problem and cant seem to figure it out.
