Question

public void runTest() throws Exception {
        InitialContext ctx = new InitialContext();
        ResourceManager bean = (ResourceManager) ctx.lookup("ejb/ResourceManagerJNDI");
        System.out.println(bean.DummyText());
}

您好。所以我正在尝试创建一个EJB应用程序，这是它的测试客户端。 JNDI查找成功但在调用“DummyText”方法时，我收到以下错误：

javax.ejb.EJBException: nested exception is: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: 
    java.rmi.RemoteException: nested exception is: javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB; nested exception is: 
    javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB (...)

这是bean类的外观：

@Stateless(name="ResourceManager", mappedName="ejb/ResourceManagerJNDI")
@Remote
@Local
public class ResourceManagerBean implements ResourceManager
{
    @EJB
    private AccessDAO accessDAO;
    @EJB
    private ResourceDAO resourceDAO;
    @EJB 
    private DepartmentDAO departmentDAO;

    (list of methods)
}

任何建议都将不胜感激。谢谢。

这是我的第一个想法。你应该有像

这样的东西

@Remote
public interface ResourceManagerSessionRemote {

    (list of methods)

}

中断远程和本地接口

@Stateless(name="ResourceManager", mappedName="ejb/ResourceManagerJNDI")
public class ResourceManagerBean implements ResourceManagerSessionRemote
{
     @EJB
    private AccessDAO accessDAO;
    @EJB
    private ResourceDAO resourceDAO;
    @EJB 
    private DepartmentDAO departmentDAO;

    (list of methods)
}

需要EJB帮助
