javax.naming。NamingException:查找失败-Intellij Idea

Question

我是java EE的新手。最近我正在使用bean无状态处理一个项目，但我得到了以下错误

豆子：

@Stateless(mappedName = "FlightServiceBean")
public class FlightServiceBean {

    public FlightServiceBean() {
    }

    // data

}

Servlet：

  private FlightServiceBean fs = null;

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {

        PrintWriter out = response.getWriter();
        out.println("The flights details servlet has been called ...");

        try
        {
            Context context = new InitialContext();
            fs = (FlightServiceBean) context.lookup("java:global/ejb1/FlightServiceBean!com.airline.service.FlightServiceBean");
// here where I got the exception
        }
        catch (NamingException e)
        {
            System.out.println("Naming Exception has occurred when trying to lookup the flightService EJB");
            e.printStackTrace();
        }

javax.name.nameingException： 在 SerialContext[myEnv={java.name.factory.initial=com.sun.enterprise.name.name.impl.SerialInitContext， java.name.factory.state=com.sun.name.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl， java.name.factory.url.pkgs=com.sun.enterprise.name} [Root exception is javax.name.NameNotFoundException： ejb1]

注意：我使用的是glassfish 5.0和jdk 1.8.0

您的EJB查找不正确。尝试将上面的行更改为

 fs = (FlightServiceBean) ic.lookup("java:comp/env/ejb/FlightServiceBean");
