Ciao Silvia,
unfortunately it's a known bug [1]. Your workflow is the right one, but
the coordinate conversions and transformations toward EPSG:3857 are not
yet supported in the latest versions of gvSIG (e.g. 2.2), because
libjni-proj4 is outdated. :( So, in the meanwhile we have to reproject
our data elsewhere (e.g. GDAL/OGR).
This issue should be fixed in gvSIG 2.3 using the official bindings of
GDAL for Java, as gvSIG core developers can confirm. Stay tuned! ;)

PS: For completeness, please report always what version and build of
gvSIG you are using.
