Hi list,
I'm using geotools2.1 and working on a servlet wich convert a GML to a
shape-File, it works well when all the features in the GML has the same
attributes, but when a feature misses an attribute it won't be added to
the shape-file and an error will be logged.
The FeatureStore "newFeatureStore" has 15 types:
[0]= DefaultAttributeType$Textual (id=224)
[1]= DefaultAttributeType$Textual (id=226)
[2]= DefaultAttributeType$Textual (id=227)
[3]= DefaultAttributeType$Textual (id=228)
[4]= DefaultAttributeType$Textual (id=229)
[5]= DefaultAttributeType$Textual (id=230)
[6]= DefaultAttributeType$Textual (id=231)
[7]= DefaultAttributeType$Textual (id=232)
[8]= DefaultAttributeType$Numeric (id=233)
[9]= DefaultAttributeType$Numeric (id=235)
[10]= DefaultAttributeType$Numeric (id=236)
[11]= DefaultAttributeType$Textual (id=237)
[12]= DefaultAttributeType$Textual (id=238)
[13]= DefaultAttributeType$Numeric (id=239)
[14]= DefaultAttributeType$Geometric (id=211)
An object in the
FeatureReader "reader" has only 14 types (schema):
[0]= DefaultAttributeType$Textual (id=330)
[1]= DefaultAttributeType$Textual (id=331)
[2]= DefaultAttributeType$Textual (id=332)
[3]= DefaultAttributeType$Textual (id=333)
[4]= DefaultAttributeType$Textual (id=334)
[5]= DefaultAttributeType$Textual (id=335)
[6]= DefaultAttributeType$Textual (id=336)
[7]= DefaultAttributeType$Numeric (id=337)
[8]= DefaultAttributeType$Numeric (id=338)
[9]= DefaultAttributeType$Numeric (id=339)
[10]= DefaultAttributeType$Textual (id=340)
[11]= DefaultAttributeType$Textual (id=341)
[12]= DefaultAttributeType$Numeric (id=342)
[13]= DefaultAttributeType$Geometric (id=307)
==> in the GML an attribut of this Feature is not set (null)
_*
My question: *_
Where and what can I do to get all Features to the GML-file, also this
Feature with null-attributes ?
Regards,
Greq
*_Source:_*
public void writeShape(DataSource dataSource)
throws Exception
{
FeatureType type = dataSource.getSchema();
String typeName = type.getTypeName();
NullFilter filter =
FilterFactory.createFilterFactory().createNullFilter();
try {
filter.nullCheckValue(FilterFactory.createFilterFactory().createAttributeExpression(type));
org.geotools.data.FeatureReader reader =
DataUtilities.reader(dataSource.getFeatures(filter));
// org.geotools.data.FeatureReader reader =
DataUtilities.reader(dataSource.getFeatures());
// now print out the feature contents (including geometric
attribute)
// create new shapefile data store
ShapefileDataStore newShapefileDataStore = new
ShapefileDataStore(shapefile.toURL());
// create the schema using from the original shapefile
newShapefileDataStore.createSchema(type);
// grab the data source from the new shapefile data store
FeatureSource newFeatureSource =
newShapefileDataStore.getFeatureSource(typeName);
// downcast FeatureSource to specific implementation of
FeatureStore
FeatureStore newFeatureStore = (FeatureStore)newFeatureSource;
// accquire a transaction to create the shapefile from
FeatureStore
Transaction t = newFeatureStore.getTransaction();
// add features got from the query (FeatureReader)
newFeatureStore.addFeatures(reader);
// filteredReader is now exhausted and closed, commit the
changes
t.commit();
t.close();
System.out.println("Successfully create new shapefile ");
} catch (Exception e) {
e.printStackTrace();
}
}
