java.lang.ClassNotFoundException：无法加载请求的类：oracle.jdbc.OracleDriver

标签： hibernate

在我的项目中，我想显示数据库中的记录。我使用的数据库是带有SQL Developer的Oracle Thin（Oracle 11g）。当我的页面使用控制器调用初始化时，我遇到了这个错误：

WELD-000049：无法在controller.EvenementController@32e0c910上调用public void controller.EvenementController.initialize（）

我使用像IDE这样的Netbeans。这是我的代码，控制器，dao，我的类+堆栈跟踪：

控制器

@Named(value="evenementController")
@RequestScoped
public class EvenementController
{

@Inject
private IEvenementServ evenementService;

private Evenement event;
private List<Evenement> evenements;
public Evenement getEvent() {
    return event;
}

@PostConstruct
public void initialize(){
    event = evenementService.getEvenement("E01");
}

public List<Evenement> getEvenements() {
    return evenements;
}

}

DAO 

@Default
@ApplicationScoped
public class EvenementService implements IEvenementService
{
private Session currentSession;
private Transaction currentTransaction;

@Override
public BcEvenement getEvenement(String pkCode) {

    Evenement evenement = new Evenement();

    try{
        this.currentSession = HibernateUtil.getSessionFactory().openSession();

        evenement = (BcEvenement)currentSession.get(Evenement.class, pkCode);


    }catch(HibernateException e){
        //e.printStackTrace();
    }finally{
        //this.currentSession.close();
    }
     return evenement;
}

Evenement JavaClass 

public class BcEvenement  implements java.io.Serializable {


 private String pkCode;
 private String nom;
 private String imgSrc;

public BcEvenement() {
}


public BcEvenement(String pkCode, String nom) {
    this.pkCode = pkCode;
    this.nom = nom;
}
public BcEvenement(String pkCode, String nom, String imgSrc) {
   this.pkCode = pkCode;
   this.nom = nom;
   this.imgSrc = imgSrc;
}
// + all GET / SET for all this attribute

在我的索引页面上，我称之为：

<h2>#{evenementController.event.imgSrc}</h2>

我的堆栈跟踪：

在构建路径上添加ojdbc14.jar它将起作用。
