Step 1) Buy a certificate. Thawte are good, since you can use the same
certificate
for IE, NS, Java Plugin, Apple Code signing, Marimba etc.
Costs about $100 + a yearly renewal fee.

IE:
2) Use 'dubuild' to create a .cab file and sign it with your certificate.
3) Use the <usespackage> and <usespackageversion> tags in the HTML file to
   import the .cab file. It will land in C:\Windows\Downloaded Program
Files.
4) Swear at MS's stupidity as you find out that the automatically created
OSD
   XML file in the cab links to a MS website adress - *which has been
moved* -
   causing every IE-signed applet in the world to break down simultaneously,
   without even an error message.
5) Loose sleep, hair and sanity as you attempt to construct your own OSD
file.

NS:
2) Rewrite all your code so that every attempt to perform a sensitive
operation is
   preceeded by the relevant call to the netscape security classes (can't
remember
   exactly right now).
3) Create a .jar and sign it with your certificate. The jar will not be
cached
   locally :-(
4) Deploy this jar as usual.
5) (Optional) Loose sleep, hair and sanity attempting to use Netscape
SmartUpdate
   to download and install the classes locally.

JP:
2) Create a .jar and sign it with your Netscape certificate.
3) Deploy. Done! In the java plugin control panel you will see a list of
'Trusted netscape
   signers' or something similar. The applet can be made 'sticky' so that
it's
   cached locally by modifying the HTML code.

I really must say that Java Plugin with Netscape signing is by far the
easiest route
to go. I guess Sun learned their lesson since creating the horribly
convoluted and
impractical security model in JDK 1.1 and 1.2.
