Hi Janusz,

Ah, the old axis order trap :-)

EPSG 4326 (which can also be accessed as DefaultGeographicCRS.WGS84 in
GeoTools) has its ordinates in longitude,latitude order

http://javadoc.geotools.fr/2.6/org/geotools/referencing/crs/DefaultGeographicCRS.html#WGS84

The CRS.decode(String code, boolean longitudeFirst) method is your
friend here.  So your code could changed to:

    CoordinateReferenceSystem targetCrs = DefaultGeographicCRS.WGS84;
    CoordinateReferenceSystem sourceCrs = CRS.decode("EPSG:32647", true);

For more information on this, have a look at these pages in the User Guide:
http://docs.codehaus.org/display/GEOTDOC/The+axis+order+issue
http://docs.codehaus.org/display/GEOTDOC/04+What+Axis+is+X

Hope this helps
Michael
