JAVA Applet Security Question

[Dancing Fingers]

Hi guys,
I'm working on a JAVA Applet that emails text within the Applet.

Within the Applet's directory is the java.policy.applet:

/* AUTOMATICALLY GENERATED ON Tue Apr 16 17:20:59 EDT 2002*/
/* DO NOT EDIT */

grant {
permission java.security.AllPermission;
};

When I tell the Applet to email I get:

Email Exception java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write) clicked

Do I need to change the JAVA security in the CLASSPATH or pass
security parameters within the Applet html tags?

Thanks.
Chris

IIRC you need to sign your applet to make this work. (see
http://www-personal.umich.edu/~lsiden/tutorials/signed-applet/signed-applet.html)

You also might want to consider using Java WebStart instead of an
applet, which is IMHO more convenient for the users if your applet is in
fact a standalone application. Depends on your use case though.

Kind regards,
Jan

You need to sign the Applet. See

Thanks guys. The applet actually has a keyboard for people with
special needs. I just wanted to give it some functionality. It will
be at http://yougarage.tv/swiper/keyboard.html..
Thanks.
