Hi Ben, thanx, I was a bit too hasty and I managed to get it working, but
your list of
references is more than welcome.
For the record, my solution was:
try {
f = new
File("/Users/turekg/Desktop/Watersheds/tccwatershed.shp");
FileDataStore store2 = FileDataStoreFinder.getDataStore(f);
SimpleFeatureSource featureSource = store2.getFeatureSource();
Filter filter = CQL.toFilter("CONTAINS(the_geom, POINT(1876437
5826750.3))");
Query query = new Query();
query.setFilter(filter);
query.setHints(new Hints(Hints.FEATURE_2D, Boolean.TRUE)); //
force
2D data
FeatureCollection srcCollection =
featureSource.getFeatures(filter);
assertTrue(srcCollection.size() == 1);
SimpleFeature[] fc = new SimpleFeature[1];
srcCollection.toArray(fc);
assertTrue(fc[0].getID().equals("tccwatershed.85"));
} catch (CQLException | IOException ex) {
ex.printStackTrace();
}
Just in case anyone else asksŠ
Gaby

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce.
Perforce version control. Predictably reliable.
