Hi Olivier,
it should work as you suggest, but unfortunately, the load process of 
libraries is not so nice in Windows.

Libraries are searched in the directory from which the application 
loaded, then in the current working directory, then in the PATH, and 
finally in the directories pointed by java.library.path. This is not a 
problem of Java, is the standard behaviour in Windows (however, 
behaviour is a bit different depending on the Windows verison).

Summarizing: in the past, we had problems because some people installed 
GDAL or other libraries in the PATH, and thus their GDAL version was 
loaded instead of gvSIG GDAL version, and this caused compatibility 
problems. To solve it, the safest way is to install our DLLs in the 
directory from which the application loaded (the JRE bin dir), and 
that's what we do. It's not clean, but it's safe.

Input is welcome.

Regards,

   César
