HI Luca at al,
An update: I was using Gremlin downloaded from the Gremlin site!!
It uses the V1.5 JAR files for Orient and I'm guessing that's why I had
both of my problems.
I've now re-pointed by pathing to use the Gremlin that comes with my
Orientdb and it's all working.....
Remote, local and not destroying the "local" database.
