You need two programs to sign your code for Internet Explorer. Both programs are available for free at http://www.microsoft.com/java/download/dl_sdk2.htm in the Microsoft Java SDK 2.01.
The two programs are: cabarc.exe – this is similar to pkzip, except it will create cab files instead of zip or jar files. signcode.exe – this program will apply your digital signature to the .cab file
The idea is that you put all you applet files (*.class, *.gif, *.au, etc.) into a cab file, then you sign the cab file.
