Problemas com Struts 2 - Erro HTTP Status 404

Java

11/03/2015

Boa noite!

Estou fazendo meu TCC e comecei a estudar Struts 2 para utilizar no desenvolvimento do meu projeto.

Utilizei a apostila da K19 - Desenvolvimento Web com Struts, e comecei a fazer o desenvolvimento do Login e Logout.

Porém, estou enfrentando algumas dificuldades que me impedem de avançar no desenvolvimento.

Baixei todos os .jar necessários, criei os arquivos log4j.xml e struts.xml (na pasta src) e alterei o arquivo web.xml, incluindo as tags abaixo:

Arquivo struts.xml 
<?xml version="1.0" encoding="UTF-8"?>  
  
<!DOCTYPE struts PUBLIC  
    "-// Apache Software Foundation // DTD Struts Configuration 2.0// EN"  
    "http://struts.apache.org/dtds/struts-2.0.dtd">  
  
<struts>  
    <constant name="struts.devMode" value="true"/>  
    <package name="default" extends="struts-default">  
        <action name="Login" class="TCC.SymbProject.actions.LoginAction">  
            <result name="success">Home.jsp</result>  
            <result name="input">Login.jsp</result>  
        </action>  
        <action name="Logout" class="TCC.SymbProject.actions.LogoutAction">  
            <result name="success">Login.jsp</result>  
        </action>  
    </package>  
</struts>

Quando eu tento executar o arquivo Login.jsp pelo tomcat, da uma mensagem de erro no browser.

"HTTP Status 404 - /TCC.SymbProject/Login.jsp message /TCC.SymbProject/Login.jsp description The requested resource is not available."

Na console aparece o seguinte, acredito que seja o motivo do erro:
