struts和hibernate整合錯誤 請各位大俠幫忙看看！

在struts 的action中調用hibernate提供的類去查找數據庫數據報錯如下：
嚴重的: Servlet.service() for servlet action threw exception
java.lang.NoClassDefFoundError

////////-==== 源代碼 -===
public Boolean checkUsersValidity(String username, String password){
try{ //在這一句報錯
Session session = HibernateSessionFactory.getSession();
if ((session.createQuery("from Users p " +
" where p.username =:username " +
" and p.password =:password")
.setString("username", username)
.setString("password", password))
.list().isEmpty())
{
return false;
}
else
{
return true;
}
}catch(Exception e){
e.printStackTrace();
return false;
}finally{
HibernateSessionFactory.closeSession();
}

}
///////===== 然后我另外寫了一個測試類，一切運行正常，在action中的代碼和下面類中代碼一樣。
public class UserDaoTest {

/**
* @param args
*/
public static void main(String[] args) {
UserDaoImp userDaoImp = new UserDaoImp();
if (userDaoImp.checkUsersValidity("wan", "123"))
System.out.print("true");
else
System.out.print("false");
}

}

找不到类，看看包导的对不对

貌似Hibernate包的问题，重新下载个再导入试试。
