Jorge,
It is possible for simple gml but most of the time you need to read the
shape file then generate your file (csv/xml) programmatically.
here are the codes that I am currently using (just adjust it for your
needs):
public SimpleFeatureSource readShpAndDbfFile(String shpFilepath) {
SimpleFeatureSource featureSource = null;
File shpFile = new File(shpFilepath);
try {
if((! shpFile.exists()) && (! shpFile.isFile())) {
String message = "SHP file is not found";
log.error(message);
throw new FileNotFoundException(message);
}
Map<String, Serializable> connect = new HashMap<String,
Serializable>();
connect.put("url", shpFile.toURI().toURL());
connect.put("charset", "Windows-31J");
DataStore dataStore = DataStoreFinder.getDataStore(connect);
String[] typeNames = dataStore.getTypeNames();
String typeName = typeNames[0];
featureSource = dataStore.getFeatureSource(typeName);
} catch (FileNotFoundException e) {
log.error(e.getLocalizedMessage());
e.printStackTrace();
} catch (MalformedURLException e) {
log.error(e.getLocalizedMessage());
e.printStackTrace();
} catch (IOException e) {
log.error(e.getLocalizedMessage());
e.printStackTrace();
} finally {
shpFile = null;
}
return featureSource;
}
SimpleFeatureSource featureSource = readShpAndDbfFile(shpFilepath);
SimpleFeatureCollection collection = featureSource.getFeatures();
SimpleFeatureIterator iterator = collection.features();
while (iterator.hasNext()) {
SimpleFeature feature = (SimpleFeature) iterator.next();
Geometry geometry = (Geometry) feature.getDefaultGeometry();
ShapeType type = JTSUtilities.findBestGeometryType(geometry);
if(! type.isPolygonType() && ! type.isLineType() && !
type.isPointType()) {
log.warnLog("warning message here");
warningCount++;
break;
}
if(geometry.isEmpty()) {
// TODO empty geometry
continue;
}
//use feature.getProperties() to get the dbf data
}

The demand for IT networking professionals continues to grow, and the
demand for specialized networking skills is growing even more rapidly.
