@EJB 注释是否适用于远程调用?

问题描述：

public class Servlet2Stateless extends HttpServlet {

@EJB private HelloUserLocal helloUser;

    @Override
    public void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {

        resp.setContentType("text/html");
        PrintWriter out = resp.getWriter();
        out.println(newSess.getName());


}

当我在不同的服务器上部署 EJB 和 Servlet 时，上面的代码行会起作用吗?或者我需要通过传统方式调用它????

will above line of code work when I have EJB and Servlet deployed on different servers? or I need to call it through traditional way????

答

如果 EJB 与您的客户端 (Servlet) 驻留在不同的服务器上，则您不能使用带有 @EJB 注释的依赖注入.

If the EJB resides on the different server than your client (Servlet) than you cannot use the dependency injection with @EJB annotation.

我猜您需要采用旧的 JNDI 方式.

I guess that you'll need to go with the old JNDI way.
