Servlets Glassfish错误：NameNotFoundException，因此servlet无法注入EJB

EJB ConverterBean应该位于何处以及如何定位，以便ConverterServlet可以注入EJB？不：

当然，我正在阅读关于这个主题的JavaEE7教程

浏览器中的InjectionException：

HTTP Status 500 - Internal Server Error

type Exception report

messageInternal Server Error

descriptionThe server encountered an internal error that prevented it from fulfilling this request.

我还尝试将servlet和ConverterBean放在同一个包中。

您似乎已经为ConverterBean定义了一个名为ConverterBeanLocal的本地接口

因此，您需要在注射点使用：

@WebServlet("/converter")
public class ConverterServlet extends HttpServlet {

    @EJB
    ConverterBeanLocal converter;

或者，您可以完全摆脱ConverterBeanLocal接口，使代码更简单
