HTTP Status 500 - Servlet.init() for servlet appServlet threw exception in spring MVC

Question

There is so many of this error in stackoverflow but I could not resolver my issue from is. Below is my simple configurations :

context.xml from my TOMCAT server where I have configured a datasource for accessing my oracle 11g server

<?xml version="1.0" encoding="UTF-8"?>
<Context>

    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>

    <!--Oracle DataSource-->
        <Resource
             name="jdbc/MonDataSource"
             auth="Container"
             type="javax.sql.DataSource"
             driverClassName="oracle.jdbc.OracleDriver"
             url="jdbc:oracle:thin:@localhost:1521:orcl"
             username="system"
             password="Azerty123"
             connectionProperties="SetBigStringTryClob=true"
             accessToUnderlyingConnectionAllowed="true"
             maxTotal="60"
             maxIdle="20"
             maxWaitMillis="10000"
         />

servlet-context.xml to show my bean configuration

    <beans:bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <beans:property name="jndiName" value="java:comp/env/jdbc/MonDataSource"/>
    </beans:bean>

    <beans:bean id="ArticleDAO" class="com.projet.testjdbc.ArticleDAOImpl">
        <beans:constructor-arg>
            <beans:ref bean="dataSource" />
        </beans:constructor-arg>
    </beans:bean>

</beans:beans>

I don't know if it'll be usefull but you have below my controller action

@Controller
public class HomeController {

    @Autowired
    private ArticleDAO aricleDAO;

    @RequestMapping(value="/liste")
    public ModelAndView home() throws IOException{
        List<Article> listArticles = aricleDAO.list();
        ModelAndView model = new ModelAndView("home");
        model.addObject("articleListe", listArticles);
        return model;
    }

}

@StanislavL I just added an excerpt of the trace (each section of it) — Bloomberg58
@SteveC But I have added the JAR in my Java Build path Libraries — Bloomberg58

root cause java.lang.ClassNotFoundException: org.springframework.jdbc.core.RowMapper

Looks like you miss a dependency. Add this to maven (if you use it)

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>2.0.6</version>
</dependency>

If not add the .jar to classpath
