The following code is currently failing with the exception below.

private X509Certificate getX509Certificate(String alias)
			throws CertificateException {
		// NOTE The default keystore password is "**********", as specified in the Sun KeyStore documentation
		// NOTE For more information, read the Sun documentation at http://java.sun.com
		X509Certificate cert  = null;
		String keystore 	= "keystore";
		try {
			cert = getX509Certificate(alias, keystore, "**********");
		}

		catch(KeyStoreException exception) {
			// A keystore exception occurred in the call to getX509Certificate, which could be indicative of a
			// bad installation
			throw new CertificateException("A keystore exception occurred accessing the default keystore."
			         + " Check your keystore installation, ensuring that the default keystore password"
			         + " is the standard Java keystore password\r\n"
			         + exception.getMessage());

So it looks like my default keystore password is not the same as that in the code above (I've replaced it with ******). How do I set the default keystore to be the same as in the code above? Please note the exact same code works for another application - and so I would like to use the same class file rather than having to change the code above.
