Currently gvSIG doesn't reproject raster data. It's under development,
and we'll see it in next versions, but not too soon.
If you need this raster reprojection you may try two approaches:
    - use gdalwarp. to generate a reprojected raster file.
    - use mapserver. You only need to serve your files localy and
mapserver will do the reprojection  'on the fly' for you.

hope it helps. greetings

The secret to programming is not intelligence, though of course that helps. It is not hard work or experience, though they help, too. The secret to programming is having smart friends. (Ron Avitzur)
