You are right, if i change the CRS with the GUI to EPSG:4326, it works. So
i thought, what's the difference between doing it there and
programmatically, where it did not work.
And i found out that apparently DefaultGeographicCRS.WGS84 is not the same
as EPSG:4326. And it does not work with DefaultGeographicCRS.WGS84. At
least there i get an invisible layer.
But now i changed
from
mapcontent.getViewport().setCoordinateReferenceSystem(DefaultGeographicCRS.WGS84);
to
mapcontent.getViewport().setCoordinateReferenceSystem(CRS.decode("EPSG:4326"));
and now it works perfectly.
Do you know, why this would make a difference and
why DefaultGeographicCRS.WGS84 could result in an invisible layer?
