javax.naming.NamingException : Lookup failed - Intellij Idea

Question

我是 java EE 的新手。最近我正在开发一个使用 bean stateless 的项目，但出现以下错误

bean :

@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.naming.NamingException: Lookup failed for 'java:global/ejb1/FlightServiceBean!com.airline.service.FlightServiceBean' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is javax.naming.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");
