RE: how can I open netcdf file in applet?

Just a quick note about using an application vice an applet;
applications can be loaded from your web server much the same as an
applet using Java Web Start.

You are correct.  The applet security model prevents applets fromopening
any connections with "other" host machines.  You have severaloptions: 1.
move the netcdf file to the host from which the applet is loaded2. use a
servlet or serlet-like approach and have the applet talk tothe servlet
(running on your host machine) which in turn reads thenetcdf file3. sign
the applet and set the permissions to allow for connections toother
hosts4. use an application rather than an applet Details can be read at:
