It would be useful to see the complete stack trace. It looks like you are trying to read a local file?? As Tom said, applets dont have that right. Tom Whittaker wrote:
Santi: In general, applets are not permitted to communicate with a host other than the one they were loaded from. In previous JVMs, this rule when using a local URL was relaxed. In later versions of Java it is more strictly enforced (as it always has been for loading applets from remote hosts). You might (I havent tried it) be able to use the AccessController.doPrivileged() method to enable this -- I just don't know if it would pop-up a user dialog for each I/O though.

In a previous version using netCDF 2.1.10 this problem didn't happen. Is there any solution to this problem without having to change java security policy files?
