Applet Security, Jar, Javakey ???

[Karbiner]

I have an applet which does some file I/O using JDBC-ODBC bridge . the
applet
works fine using appletviewer. I have tried running it in the HotJava
browser I get no
messages and no exceptions and the app no longer reads my file .
Shouldn't HotJava recognize this as a local applet and allow access to
files?
How can I get this to happen?

I have tried creating trusted identities, generating Keys, and
certificates using
Javakey . I then create a signed jar file everything seems fine.

Now when running in appletviewer I get message;
AppletSecurityException: checkwrite ?
but it does read the file.

When running in HotJava still no file reads, no exceptions nothing
Why doesn't HotJava recognize this as a signed applet (or jar file)
do I need to sign the applet itself not only the jar file even for a
local applet?
How do you add identities to the HotJava security database

thanks in advance for any help .
Jack.
