    Subject: Problems with Signing example

Hi:

I am in the final stages of the design of a major Java
applet/RMI servlet design which now requires access to the
local file system of the client. Although I can see the
local filesystem by running the applet locally, I cannot
do so if the applet is loaded remotely (even if the Plug-in
Plug-in Network access is set to 'unrestricted'.)

I am now trying to sign the applet.

However, I have not been successful with your signing example
at http://java.sun.com/security/signExample/

I am using JDK1.1.5 (Using the JavaSoft development kit)
and JDK1.1.6 (Using Symantec's Visual Cafe enviroment)

My browser is Communicator 4.04 (with the 1.1 runtime upgrade)
I am using the 1.1.1 plug-in which resides in my
h:\Program Files\Java Plug-in 1.1 directory

I have tried creating and importing the 'Duke' key using
Symantec's binarys in which case the identitydb.obj file
is placed in the E:\VisualCafedbDE\Java directory

This gave the "writefile: caught security exception' message
from http://java.sun.com/security/signExample/signedPluginEx.html

I have tried creating and importing the 'Duke' key using
the Sun binaries in which case the identitydb.obj file
is placed in the H:\jdk1.1.5 directory

This also gave the "writefile: caught security exception' message

I have also tried
- copying the identitydb.obj file to
"h:\Program Files\Java Plug-in 1.1"
- forcing the Plug-in to use the runtime in h:\jdk1.1.5
- Setting the Plug-in Network access to 'Applet Host'
and 'unrestricted'

Do you have any suggestions as to what I might try next?

Thanks for your help.
