是否可以通过servlet 3.0注释从标准web.xml文件设置welcome-file标签？

<welcome-file-list>
        <welcome-file>PageName.html</welcome-file>
</welcome-file-list>

使用ejb 3.1,servlet 3.0(glassfish服务器v3)

场景:我有MDB,它监听jms消息并处理其他会话bean(无状态).Servelet注入jms资源.

问题1:为什么servlet在使用静态声明时不能注入jms资源？

@Resource(mappedName = "jms/Tarturus")
private static ConnectionFactory connectionFactory;

@Resource(mappedName = "jms/StyxMDB")
private static Queue queue;


private Connection connection;

和

@PostConstruct
    public void postConstruct() {
        try {
            connection = connectionFactory.createConnection();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

    @PreDestroy
    public void preDestroy() {
        try {
            connection.close();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

我得到的错误是:
