[GRASS-user] r.out.gdal problem of grass6.3 in windows xp

[maven apache]

Thank you !
I have consider the space problem,and I try to avoid it:

  String filePath=file.getAbsolutePath();  // F:\anzhuang\Tomcat 5.5\....tif
  String creatLocation=System.currentTimeMillis()+"location";
  filePath=filePath.replace("\\", "\\\\"); //no matter I add this line or
not the filepath is splitted ever
  String cmd="g.proj -c georef="+filePath+" location="+creatLocation+"
datumtrans=0";
