Christopher's H2 code comments on SVN
<http://jump-pilot.svn.sourceforge.net/viewvc/jump-pilot/summer_of_code/H2-OJ/>says
"read only H2 support, still flaky", " working, but way too slow, R*Tree
implementation", but it is a start.

> Hi,

> Just had a look to Spatialite (not yet Jump DB Query connector, but it
> will come soon).
> Spatialite is very promising : I like its simplicity. I did not test its
> capabilities yet, but it can handle much more data than OpenJUMP without
> the complexity of a database like PostGIS.
>
> I'd like to let you (developper) know that h2 is a pure java database
> which has most of the SQLite qualities (simplicity, one file storage,
> in-memory mode...), and that it has now a spatial index called HatBox
> from Peter Yuill (http://hatbox.sourceforge.net/news.html). AFAIK
> Geotools has started h2/hatbox integration into Geotools.
> In hatbox, indexes seem to be build in a way which is very similar to
> spatialite way (i.e trigger updating a Rtree stired in a plain table),
> and quite different from postgis.
>
> Of course, a complete integration of h2, hatbox and OpenJUMP would be an
> interesting challenge ;-)
