Hello,
I am trying to copy the data from the SDE server to the local shapefiles.
The problem is: it does not store the geometry.
I know that the problem lies in naming the geometry field. In my SDE server
the geometry field is named 'SHAPE' while geotools always looks up for
'the_geom'.
For me it looks like a bug in geotools, but I might be wrong of course.
I use geotools 12.1 with Java 8.
Here is my method that creates the shapefile datastore based on the source
datastore definition.
private ShapefileDataStore createShapefileDataStore(File shapefileWorkspace,
SimpleFeatureType sourceFeatureType) throws IOException {
// the following file is not created, it is used here to get the
proper URL for the workspace factory
String shapefileName = sourceFeatureType.getName().getLocalPart();
shapefileName = shapefileName.toUpperCase();
File newFile = new File(shapefileWorkspace, shapefileName + ".shp");
ShapefileDataStoreFactory dataStoreFactory = new
ShapefileDataStoreFactory();
Map<String, Serializable> params = new HashMap<String,
Serializable>();
params.put(ShapefileDataStoreFactory.URLP.key,
newFile.toURI().toURL());
params.put(ShapefileDataStoreFactory.CREATE_SPATIAL_INDEX.key,
Boolean.FALSE);
params.put(ShapefileDataStoreFactory.DBFCHARSET.key,
CHARACTER_ENCODING);
ShapefileDataStore newDataStore = (ShapefileDataStore)
dataStoreFactory.createNewDataStore(params);
newDataStore.createSchema(sourceFeatureType);*//HERE IS THE PROBLEM*
return newDataStore;
}
The problem lies where I put the comment. The sourceFeatureType looks like
this:
SimpleFeatureTypeImpl KIER_LINES identified extends
Feature(NRW:NRW,IS_REAL:IS_REAL,SHAPE:SHAPE)
while the schema after the indicated line in newDataStore looks like this:
SimpleFeatureTypeImpl KIER_LINES identified extends
lineFeature(the_geom:MultiLineString,NRW:NRW,IS_REAL:IS_REAL)
This causes, that when the features are copied from the source to the
destination, the shape is ignored because the featureWriter looks for the
field 'the_geom' instead of 'SHAPE' and thus setting null as geometry.
This is done in the file ContentFeatureStore.java at line 278 (at least for
geotools 12.1 stable release).
I would be grateful for any help here
