@Inject, @ApplicationScoped - нулевой указатель исключение

Question

У меня есть простое приложение Java EE с помощью следующих зависимостей в pom.xml

<dependencies> 
<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-web-api</artifactId> 
    <version>7.0</version> 
    <scope>provided</scope> 
</dependency> 
</dependencies> 

Я Тринг впрыснуть боб в мой сервлет, но всегда получаю нулевой указатель исключение при запуске этого приложения в tomcat8

package di; 

import javax.enterprise.context.ApplicationScoped; 

@ApplicationScoped 
public class Apple { 

    public Apple(){} 

    public String getNewApple(){ 
     return "apple"; 
    } 
} 


package main; 

import di.Apple; 

import javax.inject.Inject; 
import javax.servlet.ServletException; 
import javax.servlet.annotation.WebServlet; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import java.io.IOException; 
import java.io.PrintWriter; 

@WebServlet(name = "hello", urlPatterns = {"/hello"}) 
public class Main extends HttpServlet { 

    @Inject 
    Apple apple; 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     response.setContentType("text/html;charset=UTF-8"); 
     PrintWriter out = response.getWriter(); 
     try { 
      out.println("hello"); 
      out.println(apple.getNewApple()); 

     } finally { 
      out.close(); 
     } 
    } 
} 

, когда я раскрываю это к tomEE плюс 7.0.1 моих запусков приложений, но страница пуста. Ниже приведены журналы развертывания:
