Dear gent

This is Jackie working for Korea Information Security Agency. I don't
know about Java very well. I'm very glad to get answer on the following
question.

I've known that it is not possible to read(write) local files, open
socket and so forth using remote java applets. I know that SUN corp. has
the principle of the limitation in remote Java applet, so Java applet
has restricted functions on the local computer resources.

In JDK 1.2, however, Java applet has so many functions on the local
system. I saw that it is possible to read(or write, delete) local files
and open socket and so forth in the document(Java Security Architecture,
JDK 1.2).

Is it right ?
I would like to know why did you change the principle if it is right
what I said.

Please let me know which cases are needed for java applet to access
local resource(reading file, open socket and so on).

Please let me know the reason though my misunderstanding about Java may
cause these doubts.

Thank you for your kindness.

Regard.
