hy to everybody,
a few years ago I used geotools to calculate and visualize itineraries for
bikers using shape files containing road information.
No I would like to provide an interface for the placement of antennas in the
territory, but it seems that everything changed in geotools. I did the
following to visualize a shapefile but nothing is visualized and no error
message occurs. Shapefile includes streams. Maybe someone more expert can
have a look on it?
thanks

loadShapefileIntoCatalog(SHAPEFILENAME);
...
StyleBuilder sb = new StyleBuilder();
LineSymbolizer lsStream = sb.createLineSymbolizer(Color.BLUE, 6);
Style streamsStyle = sb.createStyle(lsStream);
...
Panel mapGUI = new Panel();
jmp = new JMapPane();
jmp.setBackground(Color.white);
renderer = new StreamingRenderer();
context = new DefaultMapContext(DefaultGeographicCRS.WGS84);
context.setAreaOfInterest(demoBase.envlp_NoEdges2);
jmp.setRenderer(renderer);
jmp.setContext(context);
FeatureSource shpFS = getAShapefileFeatureSourceFromCatalog();
MapLayer m1 = new DefaultMapLayer(shpFS,streamsstyle);
demoGUI.context.addLayer(0,m1);
