java - javax.enterprise.context.RequestScoped 不存在

Question

开发环境：Netbeans 8.0.2、JAVA EE 7、GlassFish 4.1 创建一个简单的 java 类 bean

    package com.introjsf;

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;

/**
 *
 * @author xiarnousx
 */
@Named
@RequestScoped
public class CustomerCDI {

    private String firstName;
    private String lastName;

    @Inject
    private AddressCDI address;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

}

输出

Caused by: java.lang.RuntimeException: Uncompilable source code - javax.enterprise.context.RequestScoped is not an annotation type
    at com.introjsf.CustomerCDI.<clinit>(CustomerCDI.java:17)

我做了这个stackoverflow答案表明在glassfish更新后缺少包javax.enterprise.context 但是没有运气！任何建议将不胜感激谢谢
