I'm not sure about your overall configuration, but the obvious problem is that the alias that you use to load the key from keystore is invalid. Maybe you use alias of some public key instead of private? Rampart will use user as key alias when alias itself is not provided, so I would make sure that both user in service configuration and alias in properties, are set to the same value.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
