Hi ede,
>why would it be removed?
I was referring to the OGR API adding a level of abstraction above the
actual FGDB C++ API, but still being not a Java API.

to load data. that would automatically enable oj users to use all gt2
datastores. opinions?
I like using geotools too. If they implement a FGDB datastore that has read
and write access, it should be the preferred method.
