signed Applets

[Martijn deBoer]

Has anyone yet got the signed applets example listed at
http://java.sun.com/security/signExample/index.html
running under jdk 1.15 or jdk 1.13 under linux?

I get the following error:
 javakey -ic Duke Duke.x509
Error: io error[extra DER value data (constructor)]

Any ideas, suggestions?
Other workarounds?
Thanks,Martijn de Boer
