Dear all,
I seem to have problems to build a JTS geometry using Geotools
2.5.-snapshot.
I have an array of coordinates (printout below) that I extracted from a
GML polygon exterior ring position list.Running the code below I am
getting an invalid geometry. I tried to print out the geometry toText,
and am getting the followng error from the toText method:
java.lang.NullPointerException

com.vividsolutions.jts.io.WKTWriter.createFormatter(WKTWriter.java:125)
at
com.vividsolutions.jts.io.WKTWriter.writeFormatted(WKTWriter.java:290)
at com.vividsolutions.jts.io.WKTWriter.write(WKTWriter.java:226)
at com.vividsolutions.jts.geom.Geometry.toText(Geometry.java:961)
Same thing happens on the linearring, which meant that the construction
of the LinearRing is somehow incorrect. What could be the problem?
Thanks
Martin
GeometryFactory gf = new GeometryFactory(null,3035);
ArrayList<String> splitPos = splitString(poslist," ",2,",");
Coordinate[] coords = toCoordArray(splitPos, ",");
LinearRing shell = gf.createLinearRing(coords);
Polygon p = gf.createPolygon(shell, null);
p.setSRID(3035);
System.out.println("new pol: "+p.toText());
