<c:if test="${not empty param.login_error}">
    <div class="error">

Answer 3

Maybe you can try this...put

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

for c tag on jsp page, and then put something like below for error msg display

<c:when test="${param.error == 1}">
<h3 style="font-size:20; color:#FF1C19;">Wrong id or password!</h3>
</c:when>

"param.error == 1" can get return value from Spring Security(security-config.xml) like

<beans:bean id="authenticationFailureHandler" class="org.springframework.security.web.authentication.ExceptionMappingAuthenticationFailureHandler">
    <beans:property name="exceptionMappings">
        <beans:props>    
        <beans:prop key="org.springframework.security.core.userdetails.UsernameNotFoundException">/login.action?error=1</beans:prop>
        </beans:props>  
    </beans:property>
</beans:bean>

I am using spring-security v 4.0.3.RELEASE

Using the not empty did not work for me. However checking for null worked for me.

<c:if test="${ param.error ne null}">
    Display error message
</c:if>

This worked for me :

<c:if test="${not empty sessionScope.SPRING_SECURITY_LAST_EXCEPTION}">
<div class="error">
    Your login attempt was not successful, try again.<br />
    Reason: ${sessionScope.SPRING_SECURITY_LAST_EXCEPTION.message}
</div>
</c:if>

This works

<c:if test="${param.error != null}">
     Error
</c:if>
