Hello,
I am trying to create a ploygon using GeometryBuilder as follows:
GeometryBuilder geometryBuilder = new
GeometryBuilder(DefaultGeographicCRS.WGS84);
PointArray dps = geometryBuilder.createPointArray();
dps.add(geometryBuilder.createDirectPosition(new double[]{ x0, y0 }));
dps.add(geometryBuilder.createDirectPosition(new double[]{ x0, y0 + dy }));
dps.add(geometryBuilder.createDirectPosition(new double[]{ x0 + dx, y0 + dy
}));
dps.add(geometryBuilder.createDirectPosition(new double[]{ x0 + dx, y0 }));
dps.add(dps.get(0));
SurfaceBoundary surfaceBoundary =
geometryBuilder.createSurfaceBoundary(dps);
geometryBuilder.createPolygon(surfaceBoundary);
But I get the following exception at the time of array creation (
geometryBuilder.createPointArray(); ) :
Exception in thread "main" org.geotools.factory.FactoryNotFoundException: No
factory of kind "PositionFactory" found.

Does anyone have an idea what is wrong?
Thank you
