小弟学习hibernate+struts，hibernate和数据库的类库都加入了。
ACTION里却总是报java.lang.NoClassDefFoundError.
错误代码：
exception

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class testH extends HttpServlet{
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
try{
SessionFactory session = hibernateUtil.getSessionFactory();
UserForm form = new UserForm();
form.setUsername( "chen ");
session.getCurrentSession().beginTransaction();
session.getCurrentSession().save(form);
session.getCurrentSession().getTransaction().commit();
System.out.println( "sdg ");
}catch (Exception e){
System.out.println(e);
}
}
}
------解决方法--------------------------------------------------------
配置文件中SessionFactory中没配置好吧

可能是在加入HIBERNATE支持时，出现的问题。你可以再建一个工程。加入HIBERANTE。然后把LIB下的包COPY过去。试试。
