Hello,
I'm developing a tool to display netCDF files. The
program has two versions, a desktop one and an applet version. When I load from
a URL using the applet version java throws this exception:
java.security.AccessControlException: access denied
(java.io.FilePermission
http%3A%2F%2Flocalhost%3A8080%2Fsoftiam-portal%2Fusers%2Fe145%2FIPCC_ESM+Magicc_SCM%2Fmagicc_out.nc
read)

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?
