That's correct. FIDs are intended for internal JUMP use only. If you
need unique IDs, you need to define your own strategy for creating and
maintaining them. (This situation is not unique to JUMP - in my
experience you should pretty much never rely on an arbitrary piece of
software to define unique IDs for you - you just don't have enough
control and guarantee over their behaviour).

Nevermind.
I should have read the code in OJ before I tried this. It appears
FIDs are newly assigned each time a shapefile is opened, pretty
useless when trying to tie systems together with a unique ID.

In looking at the instructions at:
http://openjump.org/wiki/show/Working+with+GML
This line in the example GML template seems to infer the FID will be
output:
<property name="FID"><%=COLUMN fid%></property>
But I get "Unrecognized attribute name: FID" when I try it. Anybody
gotten this to work?

I'm using shp2pgsql to convert my OpenJump data to PostGis. It
ignores the FID column. Is there a good way I can convert my SHP
files to PostGis and retain the FIDs?
