我有一个EJB 

@Named("employeeController")
@RequestScoped
public class EmployeeController {

    @EJB
    private EmployeeDAOImpl emDAO;
}

我试图将其注入CDI托管bean中，如下所示：

Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=com.controllers.EmployeeController/emDAO,Remote 3.x interface =com.dao.implementation.EmployeeDAOImpl,ejb-link=null,lookup=,mappedName=,jndi-name=com.dao.implementation.EmployeeDAOImpl,refType=Session into class com.controllers.EmployeeController: Lookup failed for 'java:comp/env/com.controllers.EmployeeController/emDAO' 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}

但是，它会抛出以下异常：

$t0

这是如何引起的？如何解决？

1 个答案:

答案 0 :(得分：1)

而不是在EJB中注入@EJB实现注入其接口EmployeeDAO。
