I'm trying to load and write file on local disc drive using signed
javascript file. But I have experienced problem running this url:
jar:http://www.domain.com/secure-scripts...!/thepage.html
(sample)
in browser (Firefox) which simply won't work. I can't access to
html file embedded in jar file. My sample applet IO.java together
with IO.html was properly signed with valid certificate (real one,
no test certificate) by using signtool as is written here:
http://www.mozilla.org/projects/secu...d-scripts.html .
Is there someone who can help me or experienced same problems
with running embeded html file in signed jar file? Your help
is very appreciated. Thank you.
