Hi all.
I've created a self-signed certificate for testing purposes. I would =
like to import that into my IE5 and Ntescape7.1 browsers as trusted =
certificate so that the browser will accept the applet requests =
implicitly.
Can someone point me in the right direction please i.e. read-ups, howto =
documentation, etc?
Also this: my applet can access and display jpeg images but java console =
throws the typical "Access Denied" error when I try to access a local =
notepad.txt file.
HTML's, applets, jpegs and text files are all in the same directory on =
the server, I find it astounding that the applet cannot access its own =
text files, co-located in exactly the same directory without being a =
"signed applet", which brings me back to the purpose of this email...
Does anyone find this a bit over the top?
TIA :-)
