Unknown protocol: https

Question

Hello
I have just coded a program which calls upon Web servcies, I have declared on my classpath the libraries: jcert.jar, jnet.jar, jsse.jar. :
but when I compile I have the following error :
java.net.MalformedURLException: unknown protocol: https
     at java.net.URL.<init>(URL.java:586)
     at java.net.URL.<init>(URL.java:476)
     at java.net.URL.<init>(URL.java:425)
     at DynamicInvoke.findImplURI(DynamicInvoke.java:77)
     at DynamicInvoke.run(DynamicInvoke.java:62)
     at DynamicInvoke.main(DynamicInvoke.java:57)
thanks in advance

Try adding the following line to the java command,
-Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol
