DataStore can't identify geometry columns
-----------------------------------------
Key: GEOT-2347
URL: http://jira.codehaus.org/browse/GEOT-2347
Project: GeoTools
Issue Type: Bug
Components: data vpf
Affects Versions: 2.5.0
Reporter: Jeff Yutzler
Assignee: Jeff Yutzler
Priority: Critical
As reported from the field

When I run the following command
DataStore ds = new org.geotools.data.vpf.VPFLibrary( new File
"C:\test\eurnasia\lib_007" ); // where the lht file is placed
I'm getting an exception;
Exception in thread "main" java.lang.NullPointerException
at org.geotools.data.vpf.file.VPFFile.<init>(VPFFile.java:171)
at
org.geotools.data.vpf.file.VPFFileStore.findFile(VPFFileStore.java:137)
at
org.geotools.data.vpf.file.VPFFileStore.getSchema(VPFFileStore.java:86)

org.geotools.data.vpf.file.VPFFileFactory.getFile(VPFFileFactory.java:135)

at org.geotools.data.vpf.VPFLibrary.<init>(VPFLibrary.java:156)
at VpfTest.main(VpfTest.java:22)
because of this function:
public VPFFile(String cPathName) throws IOException, SchemaException {
pathName = cPathName;
inputStream = new RandomAccessFile(cPathName, ACCESS_MODE);
readHeader();
GeometryDescriptor gat = null;
VPFColumn geometryColumn = null;
Iterator iter = columns.iterator();
while (iter.hasNext()) {
geometryColumn = (VPFColumn) iter.next();
if (geometryColumn.isGeometry()) {
gat = geometryColumn.getGeometryAttributeType();
break;
}
}
SimpleFeatureType superType = null;
// if it's a text geometry feature type add annotation as a super type
if (pathName.endsWith(TEXT_PRIMITIVE)) {
superType = AnnotationFeatureType.ANNOTATION;
}
SimpleFeatureTypeBuilder b = new SimpleFeatureTypeBuilder();
b.setName( cPathName );
b.setNamespaceURI("VPF");
b.setSuperType(superType);
b.addAll( columns );
b.setDefaultGeometry(gat.getLocalName());
featureType = b.buildFeatureType();
}
gat is null when trying to get localName()
geometryColumn.isGeometry() is allways false !
