I have no idea about Postgis, but don't you need to use as AsBinary or so?

Hi
I'm using the OpenJump (v1.2) classes to read data from a postgis
database but I have some problems reading geometry columns. My code
looks as follows:
PostgisDataStoreDriver PgDriver = new PostgisDataStoreDriver();
PostgisDSConnection PgConn = (PostgisDSConnection)
PgDriver.createConnection(params);
AdhocQuery query = new AdhocQuery("SELECT * FROM public.geo_gemeinden_v");
PostgisFeatureInputStream stream = (PostgisFeatureInputStream)
PgConn.executeAdhocQuery(query);
System.out.println(stream.getFeatureSchema().getGeometryIndex()); // ->
row number "2"
while(stream.hasNext()) {
System.out.println(stream.next().getAttribute("name"));
//System.out.println(stream.next().getGeometry());
}
The while loops just returns: "Unknown WKB type 48". Did I misunterstood
something with the AdhocQuery or do I have to treat geometry columns
different. A query like "SELECT name, gem_bfs FROM
public.geo_gemeinden_v" works perfect.
Thanks for any help!
regards
Stefan
