Question

我从数据库创建了实体类，然后我从实体类创建了会话bean 并且当我试图测试我的数据到达实体类时，我已经在会话bean类上创建了一个junit测试，但我查找失败“根异常是javax.naming.NameNotFoundException：EmpTableFacade！Beans.EmpTableFacade找不到，即使我使用EJB注入然后我尝试通过创建使用会话bean的类来手动测试我的代码，但这里有相同的异常。

我认为部署员工的错误但我不知道我在哪里做错了这是会话bean界面。

    package Beans;

    @Local
    public interface EmpTableFacadeLocal {

        void create(EmpTable empTable);

        void edit(EmpTable empTable);

        void remove(EmpTable empTable);

        EmpTable find(Object id);

        List<EmpTable> findAll();

        List<EmpTable> findRange(int[] range);

        int count();

    }



 and this is the test class

                props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
                // glassfish default port value will be 3700,

            EmpTableFacade empTableFacade=(EmpTableFacade)

        }
    }

这是例外

您需要使用Remote接口公开您的bean。 Local接口仅适用于同一JVM中的调用，而不是您的情况。

JNDI名称也看起来不对。您没有指定使用哪个ejb或服务器版本对解决此类问题很重要，但我认为link可以帮助您定义正确的JNDI名称条目。

另请注意，根据glassfish doc。

每个可移植的全局JNDI名称在部署期间打印到server.log。

查找失败“根异常是javax.naming.NameNotFoundException”
