Spring security xml, form not working

I am new to spring and I am lost in XML configuration. I want to use spring-security 3.2 to protect my Admin area and Resources area. So i have 2 "entry points":

Login form and mvc area:

/admin

oAuth2, rest resources (not an issue at the moment):

/api

When I enter the credentials i get 404. This is the page with log in form:

http://localhost:8080/springmvcrest/admin/login

On log in I get this:

http://localhost:8080/springmvcrest/j_spring_security_check

        model.addAttribute("message", "Login...");

        String name = "";
        name = principal.getName(); //get logged in username
        return "redirect:/admin/springmvc/greeting/"+name;
    }
}

/WEB-INF/view/login.jsp

<form id="login" action="<c:url value="/j_spring_security_check"></c:url>" ....

I have tried /j_spring_security_check or ../j_spring_security_check or /admin/j_spring_security_check ... no success.

I can log in when the http is auto-config="true" and url-pattern in web.xml is set to /*

spring-mvc-4.0, spring-security-3.2
