thank you

while (rs.next()) {
//g1 =  
com.vividsolutions.jts.geom.Geometry.wkbReader.read(WKBReader.hexToBytes(rs.getString(1)));
g1 = org.gdal.ogr.Geometry.CreateFromWkb(rs.getBytes(1));
if (g1 != null) {
System.out.println( g1.GetGeometryType());
}

}

g1 returns null.
can you tell me what the wrong is ?

regards
