java.awt.Polygon? It's not very efficient, but you could try to read
the PostGIS geometry as WKB using JTS
(http://www.vividsolutions.com/JTS/JTSHome.htm), then iterate through
the coordinates in the exterior ring, extracting the raw x,y to pass as
an argument to java.awt.Polygon (int[] xpoints, int[] ypoints, int npoints)
This thread has some thoughts to read from a PostGIS database:

Hope this helps.

hi list,
i am just wondering how i can draw to screen a Poylgon (or a Polyline/Point)
which is stored in a postgis db?
i have geographical coordinates stored in a table with the geometry coloumn
being in the wkb format. i know, how to connect to my postgres db and how to
query the geometry from that table (e.g. select the_geom from testtable
where...). now i would need some javaclasses/javamethods which create Polygons
(Polylines/Point) as i walk through the result set. i know that there is a
wkb4j library, but unfortunately this badly documented and i don't know how to
use it.
has anybody experiences with that issue? i would appreciate any help.
thanks in advance, stefan
