How to sign an applet for MS JVM and Sun JVM?

I have a Java program written for 1.1 that can be standalone, or as an applet. However, since it is our backup program if our VB program fails to install, we prefer it to not be installed onto the client's computer, so as far as I can tell, I need to use it as an applet. Also, since our clients can be people using Win98 and MS JVM, it needs to be able to work with both MS JVM and Sun's.

The applet is hosted on the server it needs to open sockets with, however, in order to add proxy support to the applet, from what I can gather, is that it needs to be signed in order to have permissions to open sockets with the proxy instead.

Doing a search on the web, I've found that I can sign it with MS Java SDK, or Sun's Javakey. I can't find any links that will allow me to get the MS SDK. From the steps I've read on Javakey, it requires the client to manually accept certificates in the console, which is unacceptable.

How would I sign this applet so that it works on both JVMs and causes little (a security warning to be accepted at most) hassle for the client?

You need to produce both a signed cab and a signed jar.

Yes, how would I do this?

Currently, I am trying to get at least one authentication scheme going, so I have Basic added into the code. I'm planning to get Digest and maybe NTLM/Kerberos support added in eventually.

Does your applet need to connect to a box other than the one it loaded from?

This link gives methods for 1.2.2/1.3. I am using 1.1.

This link gives methods mainly for 1.2+, but also has the MS Authenticode method which will work, but I need the MS SDK for.
I will award points if you can get me the link to the MS Java SDK, otherwise, this solution is a nogo.

> Does your applet need to connect to a box other than the one it loaded from?
Yes, it does. Our software needs to be able to work through a client's own proxy.

it includes details for signing both for plugin and for MS VM.

The MS JDK is no longer available.

Hi,

Now Microsoft no longer support Java, so might hard to get the MS SDK, and as objects say, can consider no longer available, for information, maybe you can try this address.

Why not u use up the Sun SDK to sign the applet ?
