Answer 1

The default login endpoint for login submit action is /login. You have in your login.html the endpoint j_spring_security_check where spring don't knows how it handle this mapping. So try it also with input elements with ids/names username/password:

<form  action="/login" name="f" method="post" >
    <input id="username" name="username" type="text" />
    <input id="password" name="password" type="password"/>
    <input name="submit" id="button" type="submit" value="enter" />
</form>

Please modify both entries (servlet-config.xml, spring-security.xml) in <context:component-scan base-package="com.sam.*"/>. Change the url-mapping to:

<servlet-mapping>
    <servlet-name>ISMServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Answer 2

I think that csrf protection is enabled by default in sprng-security 4. So add this line in your login form

<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
