Hi Cris,
Not sure. The ruta filename looks a bit odd to me with backslashes. Do you get
the same problem if you replace the "\" with "/"?

Subject: [Geotools-gt2-users] Fwd: [Create a SHP file with a polygon]
Hello to all,
I'm trying to create a SHP with a simple polygon but I'm not able to achieve it.
Here is my sample code:
--

public PruebaGeotools() {
//Create de SHP Type
SimpleFeatureType TYPE = createFeatureType();
DefaultFeatureCollection collection = new DefaultFeatureCollection();
try {
GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();
Coordinate[] coords =
new Coordinate[] {new Coordinate(4, 0), new Coordinate(2, 2),
new Coordinate(4, 4), new Coordinate(6, 2), new Coordinate(4, 0) };
LinearRing ring = geometryFactory.createLinearRing( coords );
LinearRing holes[] = null; // use LinearRing[] to represent holes
Polygon polygon = geometryFactory.createPolygon(ring, holes );
SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(TYPE);
featureBuilder.add(polygon);
featureBuilder.add("Data1");
featureBuilder.add("Data2");
SimpleFeature feature = featureBuilder.buildFeature("Element 1");
collection.add(feature);
//SAVE DATA TO A FILE
String ruta = "C:\\Data\\Test.shp";
File file = new File(ruta);
ShapefileDataStoreFactory dataStoreFactory = new ShapefileDataStoreFactory();
Map<String, Serializable> params = new HashMap<String, Serializable>();
params.put("url", file.toURI().toURL());
params.put("create spatial index", Boolean.TRUE);

dataStoreFactory.createNewDataStore(params);
newDataStore.createSchema(TYPE);

featureStore.setTransaction(transaction);
try {
//ADD ALL THE FEATURES
featureStore.addFeatures(collection);
transaction.commit();
} catch (Exception problem) {
problem.printStackTrace();
transaction.rollback();
} finally {
transaction.close();
}
System.exit(0); // success!
} else {
System.out.println(typeName + " does not support read/write access");
System.exit(1);
}
} catch(Exception e) {
e.printStackTrace();
}
}
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", Polygon.class);
builder.length(15).add("Name1", String.class); // <- 15 chars width for name
field
builder.length(15).add("Name2", String.class); // <- 15 chars width for name
field
// build the type
final SimpleFeatureType LOCATION = builder.buildFeatureType();
return LOCATION;
}
public static void main(String args[]) {

}
}

What I'm doing wrong?
Thanks in advance!
