[Geotools-gt2-users] Some problems creating LineString objects.

[Ricardo P. <ric...@ed...>]

Hi,

=20

I'm doing some dummy HelloWorld examples with GeoTools version 2.3.0,
but now I'm blocked.

I already created a Point with the GeometryFactory class, but when I
tried the LineString, I'm keep getting NullPointerException in the last
code line.

(The same problem has happen for the LinearRing object)

The code that I made is below:

import com.vividsolutions.jts.geom.Coordinate;

import com.vividsolutions.jts.geom.GeometryFactory;

import com.vividsolutions.jts.geom.LineString;

=20

public class DummyHelloWorld {

=20

      public static void main(String[] args) {

            GeometryFactory geometryFactory =3D null;

            Coordinate[] lineSegments =3D new Coordinate[5];

           =20

            lineSegments[0] =3D new Coordinate(5.0d,5.0d);

            lineSegments[1] =3D new Coordinate(6.0d,5.0d);

            lineSegments[2] =3D new Coordinate(6.0d,6.0d);

            lineSegments[3] =3D new Coordinate(7.0d,6.0d);

            lineSegments[4] =3D new Coordinate(7.0d,7.0d);

         =20

          LineString line =3D
geometryFactory.createLineString(lineSegments);

      }

}

Thanks in advance for any help,
