Hi

When I start my Applet I need to retrieve a db4o database file from a
server. I tried reading the file with an InputStream and then writing it
to a FileOutputStream, but this doesn't work, because when trying to
write a File, I get some kind of SecurityException (don't remember
exactly). Tried right now again and now I get a AccessControlException
(access denied) when trying to open an InputStream. Yesturday I was able
to open an InputStream.

Any suggestions on how could I get the requested file? And later, if the
database is modified, write it back to the server? (Servlets can't be
used on this server for some reason)

code:
============================================
public class AppletTest extends JApplet {

  URL url;
  URLConnection conn;

  public void paint( Graphics g ) {
    try {
      url = new URL( http://www.tac.ee/~johan/java/AppletTest/test.db4o" );
      conn = url.openConnection();

      InputStream input = conn.getInputStream();
      byte[] buffer = new byte[512];
      int read = -1;

      FileOutputStream fileOut = new FileOutputStream("temp.db4o");
      while ((read = input.read(buffer, 0, buffer.length)) != -1)
        fileOut.write(buffer, 0, read);

      fileOut.close();
      input.close();
    }
    catch( allkindsofexceptions ){}
  }
}
=============================================

I use the server in this example only for testing, because I don't
currently have access to the final server where the completed
application will reside.
