我正在使用Eclipse,我想使用Glassfish和MySQL创建企业应用程序。EJB在企业应用程序中未被识别
我创建了一个名为WeatherEJB和WeatherWeb的EJB和WEB模块的企业应用程序项目。
在WeatherEJB项目中,我使用JPA生成实体表,使用JPA创建一个无状态的远程会话bean,名为CountryDAO,实现CountryDAOBean,以便覆盖生成的实体Country。
在WeatherWeb项目中,我添加了对Java Build浴中的WeatherEJB项目的引用,项目引用和模块依赖项。
然后,在WeatherWeb项目中,我创建了一个名为CountryController(在“请求”范围)托管bean,它看起来像这样:
import javax.ejb.EJB;
import model.Country;
import service.CountryDAO;
public class CountryController
{
@EJB
CountryDAO countryDao;
private Country country;
public CountryController()
{
country = new Country();
}
public String saveCountry()
{
String returnValue = "success";
try
{
countryDao.saveCountry(country);
}
catch (Exception e){
e.printStackTrace();
returnValue = "failure";
}
return returnValue;
}
public Country getCountry(){
return country;
}
public void setCountry(Country country){
this.country = country;
}
}
虽然我可以成功部署在Glassfish应用程序,当我尝试访问使用CountryController的jsf,我得到以下错误:
type Exception report

我在想什么?或者我做错了什么?
