Probably when you call the method execute the object "form" is not initiated, you should check the code where you call the method "execute".

In the previous code you should have something like:

LoginForm form = new LoginForm(.....);
//probably something in the middle
ActionForward af = execute(mapping, form, request, response);

I think you don't have the line LoginForm form = new LoginForm(.....);
