远程服务的EJB依赖注入在Glassfish上失败

我无法获得依赖注入为我的远程服务工作，我找不到原因。我想要一个RemoteService的实例，所以我写了。远程服务的EJB依赖注入在Glassfish上失败

@EJB(name="RemoteService") 
private RemoteService service;

和bean本身定义的mappedName =“RemoteService：

@Stateless(mappedName = "RemoteService") 
public class RemoteServiceBean implements RemoteService

当我尝试运行此代码，我得到一个InjectionException：

EJB5070: Exception creating stateless session bean : [{0}]

我没有EJB配置文件，但我不需要任何，对吧？远程服务运行在与尝试引用它的服务相同的glassfish实例上。检查glassfish admin中的JNDI浏览器验证EJB是否已经被d eployed使用正确的JNDI名称，如果我在构造函数中手动删除@EJB注释并做查找它也可以工作：

public OrderServiceBean() 
    { 
    try 
    { 
     final Properties properties = new Properties(); 
     properties.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory"); 
     properties.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming"); 
     properties.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl"); 
     properties.setProperty("org.omg.CORBA.ORBInitialHost", "localhost"); 
     properties.setProperty("org.omg.CORBA.ORBInitialPort", "3700"); 

     final InitialContext initialContext = new InitialContext(properties); 
     this.service = (RemoteService) initialContext.lookup("RemoteService"); 
    }

想法？

我不敢相信我没有尝试过，但它似乎我没有，我显然没有尝试通过mappedName引用EJB。所以改变这个参考使它工作：

@EJB(mappedName="RemoteService") 
private RemoteService service;
