Nullpointerexception when trying encryption example..

[Shahzad Younas <sh...@bananacomputers.com>]

Hi all,
 
I am trying the example given to encrypt a message:
 
WSEncryptBody encryptor = new WSEncryptBody();
   Crypto crypto = CryptoFactory.getInstance("crypto.properties");
   Vector parts = new Vector();
   org.apache.ws.security.SOAP11Constants s = new
org.apache.ws.security.SOAP11Constants();
   WSEncryptionPart part = new
WSEncryptionPart(s.getBodyQName().getLocalPart(),
                                                s.getEnvelopeURI(),
                                                "Content");
   parts.add(part);
   encryptor.setParts(parts); // this is optional since the body is
encrypted by default
   d = encryptor.build(d, crypto);
 
(as found here http://ws.apache.org/ws-fx/wss4j/api.html)
 
However, when I run it, I am getting a null pointer exception (below). I
have looked on the mailing list but cant seem to find any reference to this
problem. I have made sure my crypto.properties is on the class path as is my
keys folder with the key in it.
What am i doing wrong?
 
Also, is there another mailing list as this one is extremely quiet!
Thanks
Shahzad
