Sign Applets

I coded an applet which writes a executable file to the client's directory system and then executes this file.

How can I sign this applet, so that it could work.

Can anybody give me the whole procedure to do this???

I read about in Sun's site and it was really confusing.

Thanks in advance.

Hi,

Just of the bat, you are going to need a certificate first (thawte, verisign), you then need to
import that into netscape and IE.

You will need extra security source code for Netscape:

import netscape.security.PrivilegeManager;
Your Code . . . . . . .

System.out.println("Trying to acquire permission to read system files...");

try
{
PrivilegeManager.enablePrivilege("UniversalFileRead");
// PrivilegeManager.enablePrivilege("SuperUser");
System.out.println("\tSuccess! Privilege is enabled.");
}
catch (netscape.security.ForbiddenTargetException ee)
{
System.out.println("\tFailed! Permission to read system files denied by user.");
}
catch (Exception pe)
{
System.out.println("\tFailed! Unknown exception while enabling privilege.");
pe.printStackTrace();
}

You are going to need the netscape signtool to create and sign your jar for netscape

and you will need the cabsdk (cabarc and signcode) to create and sign the cab file
for IE.

These methods are for 1.1 applets I think the process has possibly changed for 1.2
applets, but hey, who wants to deploy a swing applet on the internet, only 2% of users
would be able to use it and the others would all need to upgrade Internet connections,
VM's and the applets would still be to slow, what I am saying is, if an applet then keep
it AWT.

Of couse the above mentioned URL's will give you more detailed info.

Hope this helps
