Jakarta ee Java EE Web应用程序uNetBeans中出现错误

我正在尝试在netbeans中使用mysql db创建一个简单的web应用程序。 但是当我运行应用程序时，我得到了以下错误。 我不知道这个错误说明了什么。任何帮助都将不胜感激

Exception attempting to inject Remote ejb-ref name=PresentationLayer.PlacesManagedBean/placesSessionBean,Remote 3.x interface =LogicLayer.PlacesSessionBean,ejb-link=null,lookup=,mappedName=,jndi-name=LogicLayer.PlacesSessionBean,refType=Session into class PresentationLayer.PlacesManagedBean: Lookup failed for 'java:comp/env/PresentationLayer.PlacesManagedBean/placesSessionBean' 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}

编辑： 堆栈跟踪：

EJB用于托管bean。。代码如下：

package PresentationLayer;

import DataLayer.*;
import LogicLayer.*;

import java.io.Serializable;
import java.util.List;
import javax.ejb.EJB;
import javax.inject.Named;
import javax.enterprise.context.Dependent;
import javax.annotation.PostConstruct;

@Named(value = "placesManagedBean")
@Dependent

public class PlacesManagedBean implements Serializable{
@EJB
private PlacesSessionBean placesSessionBean; 
private List<Places> places;

public PlacesManagedBean() {
}
@PostConstruct
public void init()
{places = placesSessionBean.getPlaces();}

public List<Places> getPlaces ()
        {return places;}

public void setPlaces(List<Places> places)
    {this.places = places;}    
}

包呈现层；
导入数据层。*；
导入逻辑层。*；
导入java.io.Serializable；
导入java.util.List；
导入javax.ejb.ejb；
导入javax.inject.Named；
导入javax.enterprise.context.Dependent；
导入javax.annotation.PostConstruct；
@命名（value=“placesManagedBean”）
@依赖的
公共类PlacesManagedBean实现可序列化{
@EJB
私人配售sessionbean配售sessionbean；
私人名单；
公共场所托管bean（）{
}
@施工后
公共void init（）
{places=placesSessionBean.getPlaces（）；}
公共列表getPlaces（）
{返回位置；}
公共空间设置位置（列出位置）
{this.places=places；}
}

钥匙在这里：

Remote 3.x interface =LogicLayer.PlacesSessionBean,ejb-link=null,lookup=,
mappedName=,jndi-name=LogicLayer.PlacesSessionBean,refType=Session 
into class PresentationLayer.PlacesManagedBean: Lookup failed for 
'java:comp/env/PresentationLayer.PlacesManagedBean/placesSessionBean'

在这里：

Caused by: javax.naming.NamingException: Lookup failed for

SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory,

java.naming.factory.url.pkgs=com.sun.enterprise.naming} 
[Root exception is javax.naming.NameNotFoundException: 
LogicLayer.PlacesSessionBean#LogicLayer.PlacesSessionBean not found]

似乎

PlacesSessionBean

是一个远程bean，JNDI无法定位它。您必须研究如何查找远程EJB，或者，如果不需要远程bean，如何使EJB成为本地bean和/或无接口bean

有用的链接：

为了获得更好的帮助，请发布EJB接口/实现定义以及相关的EJB描述符（如果有）。

这是EJB注入期间发生的异常。请发布完整的堆栈跟踪和执行EJB注入的代码部分（查找@EJB和类似注释）。@MiljenMikic。。。我已经添加了应用程序的堆栈跟踪和托管bean。若您的

PlacesSessionBean

实现了一些远程接口，那个么您应该将声明更改为：

@EJB-private-PlacesSessionRemoteInterface-PlacesSessionBean
