open ecw files offline as base map

idozoar

Hi,

I'm new to ArcGIS runtime sdk for java.
I need my app to open my own base map that represented by about 6-7 .ecw files (including of course matching .aux files).
How do I add a layer from .ecw file to JMap?
I  tried:
JMap map = new JMap(); ... String rasterPath = "k5521.ecw"; //the file is in the folder of the project
FileRasterSource rasterSource;

try {

     rasterSource = new FileRasterSource(rasterPath);

     RasterLayer rasterLayer = new RasterLayer(rasterSource);

     map.getLayers().add(rasterLayer);

} catch (IllegalArgumentException iex) {

// handle exception

} catch (FileNotFoundException fe) {

// handle exception

} catch (RuntimeException re) { // handle exception }

and also:

FileRasterSource rasterSource = new FileRasterSource("k5521.ecw");

rasterSource.project(map.getSpatialReference());

RasterLayer rasterLayer = new RasterLayer(rasterSource);

map.getLayers().add(rasterLayer);

what am I doing wrong?

idozoar

it doesn't work, here is the whole code, what am I getting wrong?

what needs to be the value in "rasterPath"? again: "k5221.ecw"?
