Answer 2

Try import the class.

Modify your jsp's first line to look like this;

<%@ page language="java" import="javax.servlet.jsp.PageContext" contentType="text/html; charset=ISO-8859-1"pageEncoding="ISO-8859-1"%>

Answer 3

Add to the pom.xml dependencies:

     <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.1</version>
        <scope>provided</scope>
    </dependency>

JSP:

Make sure to add on jsp, before tag:

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

Get the context on JSP:

<c:set var="contextPath" value="${pageContext.request.contextPath}"/>

Import style css:

<link type="text/css" rel="stylesheet" href="${contextPath}/css/yourCssFile.css"/>

Dispatcher-servlet:

On your "spring-dispatcher-servlet.xml" add the following lines:

<beans xmlns="... xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="...
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<mvc:resources mapping="/resources/**" location="/resources/css/" />

Maybe, you need to add this adapters:

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> [Optional]
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="order" value="0"/>
</bean>

Answer 4

Try setting the servlet-api dependency in your pom.xml to provided. This jar maybe conflicting with the tomcat provided servlet-api.jar.

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>

Also be sure to include the jsp-api dependency, once again set as provided:

    <!-- Servlet -->
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>javax.servlet.jsp-api</artifactId>
        <version>2.3.3</version>
        <scope>provided</scope>
    </dependency>

Make sure all of your maven dependencies are being used to build the project by right clicking your project > Properties. On the deployment assembly tab click the add button, then Java Build Path Entries, then Maven Dependencies and finally Finish.

You may also need to add your maven dependencies to the build path. Right click your project > Maven > Update Project Configuration.

This will solve the problem 

<!-- Need this to compile JSP -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>

Answer 6

This alternative worked for me <%=request.getContextPath()%> which gets the Application context.
