jks keystore Invalid keystore

[BALDWIN, ALAN J [AG-Contractor/1000]]

Hi all, I'm trying to encrypt a soap message using symmetric AES encryption.  I 
have generated a key, which is encrypting and decrypting correctly (it's been 
tested).  Here is the code used to generate the key.  It is a jks type 
keystore.  I copied this file into my webservice source code, and ran a test 
case to pass in the security headers to the webservice.  The stack trace is 
what I get.  Is there a problem with jks keystores?  Is there something I'm 
missing?

Thanks a lot!

...key generation code...

    Security.addProvider(new com.sun.crypto.provider.SunJCE());

    KeyGenerator kg = KeyGenerator.getInstance("AES");

    Key key = kg.generateKey();

    KeyStore ks = KeyStore.getInstance("jks");
     
    ks.load(null,"security".toCharArray());
    ks.setKeyEntry("ecms",key,"security".toCharArray(), null);
      
    ks.store(new FileOutputStream("ecms.jks"), "security".toCharArray());
