Hello,
With a help of Mr. Jan Jezek I was finally able to resolve my problem.
The final solution looks like this:
Coordinate coord = new Coordinate(1038922.1, 735575.14);
GeometryFactory geometryFactory = new GeometryFactory();
final com.vividsolutions.jts.geom.Point geoPoint =
geometryFactory.createPoint(coord);
CoordinateReferenceSystem sourceCRS =
CRS.decode("EPSG:2065");//Krovak
CoordinateReferenceSystem targetCRS =
CRS.decode("EPSG:4326");//WGS-84
MathTransform transform = CRS.findMathTransform(sourceCRS,
targetCRS, false);
final com.vividsolutions.jts.geom.Geometry geometry =
JTS.transform(geoPoint, transform);
final Coordinate coordinate = geometry.getCoordinate();
System.out.println("coordinate = " + coordinate);
I used these maven dependencies:
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-referencing</artifactId>
<version>9.0-RC1</version>
