Re: java.security.AccessControlException opening from an applet

Hi again John,
I have checked the program using the URL class and works fine, no secutity problems (I also worked with attribute debugLeaks commented at HTTPRandomAccessFile3.java). This is the method I have changed at N3iosp.java (from line 87): 

 
//////////////////////////////////////////////////////////////////////////////////////
 // read existing file
public void open(ucar.unidata.io.RandomAccessFile raf, ucar.nc2.NetcdfFile ncfile, 
                  ucar.nc2.util.CancelTask cancelTask) throws IOException {
   this.raf = raf;
   this.ncfile = ncfile;

if(!raf.getClass().getName().equals("ucar.unidata.io.http.HTTPRandomAccessFile3")){     File file = new File( raf.getLocation());     if (file.exists())       lastModified = file.lastModified(); } else {     
try{      URL url = new URL(raf.getLocation());     HttpURLConnection con = (HttpURLConnection)url.openConnection();     con.connect();   lastModified = con.getLastModified();   con.disconnect();   }   catch 
(Exception e)   {   // Do nothing   } }Regards,Santi----- Original Message -----From: "S Santos" <address@hidden>To: "John Caron" <address@hidden>Cc: <address@hidden>;

omAccessFile when you work with HTTPRandomAccessFile3>>    - It isn't possible to load from an applet withucar.nc2.NetcdfFile.open() using a url allowed by the sandbox. This waspossible in previous versions of netcdf. This could be caused by the usingof the class File to check the existence of the file (the 
applet see thatlike a local file and throws a security exception). If you use the class URLwhen raf is an HTTPRandomAccessFile3 to check this, probably all will workfine with applets (See lines 92 to 94 at N3iosp.java). I'll check that.>> Regards,>> Santi> ----- Original Message -----> From:
