Thanks for your prompt reply Jody! I do see a SimpleFeatureTypeBuilder#setDefaultGeometry(String) and will try that. I do notice that the javadocs say:
"A default geometry for the feature type can be specified explictly via |setDefaultGeometry(String)| <http://geotools.org/javadocs/org/geotools/feature/simple/SimpleFeatureTypeBuilder.html#setDefaultGeometry%28java.lang.String%29>. However if one is not set the first geometric attribute (|GeometryType| <http://geoapi.sourceforge.net/snapshot/javadoc/org/opengis/feature/type/GeometryType.html>) added will be resulting default. So if only specifying a single geometry for the type there is no need to call the method." so there may be a bug lurking somewhere here. Also, it appears that SimpleFeatureCollection, SimpleFeatureSource no longer exist and that the following lines needed to be changed in the example: //SimpleFeatureCollection collection = FeatureCollections.newCollection(); FeatureCollection<SimpleFeatureType,SimpleFeature> collection = (FeatureCollection<SimpleFeatureType,SimpleFeature>)FeatureCollections.newCollection(); //SimpleFeatureSource featureSource = newDataStore.getFeatureSource(typeName); FeatureSource<SimpleFeatureType,SimpleFeature> featureSource = (FeatureSource<SimpleFeatureType,SimpleFeature>)newDataStore.getFeatureSource(typeName); Does that seem reasonable to you? Thanks again for your help! --john On 05/06/2010 10:08 AM, Jody Garnett wrote: > It may be the example that is wrong; I can see the > builder.add("Location",Point.class) line ... > can you try and see if there is a builder method to set the default geometry? > I assumed it would pick up the first geometry all on its own .... > > Jody > > On 07/05/2010, at 1:51 AM, John Cartwright wrote: > > >> Hello All, >> >> I'm trying to follow the very nice Csv2Shp example >> (http://geotools.org/examples/csv2shp.html) using version 2.6.3 and am >> having a little trouble. >> >> Using the recommended alternative method for creating a SimpleFeatureType: >> >> private static SimpleFeatureType createFeatureType() { >> >> SimpleFeatureTypeBuilder builder = new SimpleFeatureTypeBuilder(); >> builder.setName("Location"); >> builder.setCRS(DefaultGeographicCRS.WGS84); // <- Coordinate >> reference system >> >> // add attributes in order >> builder.add("Location", Point.class); >> builder.length(15).add("Name", String.class); // <- 15 chars width >> for name field >> >> // build the type >> final SimpleFeatureType LOCATION = builder.buildFeatureType(); >> >> return LOCATION; >> } >> >> I find that the subsequent call "newDataStore.createSchema(TYPE);" throws a >> NPE, apparently because the the >> GeometryDescriptor is null (ShapefileDataStore.java: line 815). >> >> Can someone please explain what I'm doing wrong here? >> >> Thanks! >> >> --john >> >> >> >> >> ------------------------------------------------------------------------------ >> _______________________________________________ >> Geotools-gt2-users mailing list >> [email protected] >> https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users >> > > ------------------------------------------------------------------------------ > _______________________________________________ > Geotools-gt2-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users > >
