Where and How Do I Get the Key File?
We make this as simple and quick as
we can, since we want you to use the applets as easily as possible.
Along the top right of each
applet's pages, you'll see a link labeled "Get Free Key" -- just click on
it, and it will open a form. Fill in the information -
please read the instructions about your URL with care! -
and your key will be created. You'll then be directed to a link
where you can immediately download a zipped copy of your unique key file.
We also e-mail a copy of the zipped
key file, as well as the download link once again, to the e-mail address you provide in
the key, and place the key file to the same directory where
your applet resides -- and be sure to send it up in ASCII, not
You do NOT need a key file to use our applets off your hard
also note that each key file is
most common problems our visitors write us about concerning
key files are:
too much information in the key file form's URL box... all
you need there is the domain name, so read the
the key up in binary rather than ASCII
putting the key file, the class file, any files associated
with the applet, and the html page calling the applet all
in the same directory to get started
What Key Files Are
Key files are quite commonly used with professional
JAVA applets. They are a means of protecting an applet from unauthorized use.
In general, if the correct key file is not present in the same directory as the applet for
which it is issued, the applet will run on your hard drive -- but not on your website.
CodeBrain key files are very small (128-256 bytes).
CodeBrain applets, you do not
need a key file to try out the applet on your hard drive. Our applets do NOT
look for the key file unless they are actually on your web site.
