ここで何が問題なのかわからないので、助けてください。これは例外です:

この例外がどこから来たのかわかりません。この問題に光を当ててください。ありがとう！
EDIT1 : UserBean.java コードの追加:
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
class UserBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
private User user;
}
ところで、重大: コンテキスト [/projectName] の起動は、以前のエラーが原因で失敗しました
