JSP+HIBERNATE问题
我用JSP+HIBERNATE开发项目。
Hibernate有关的类全部编译成功，并且放到了WEB-INF/classes/mypack里。
有关Hibernate的XML文件也都配置完毕。
Hibernate包下的hibernate2.jar和LIB目录下的所有JAR都放到了项目的WEB-INF/LIB目录下。
在JSP中引用了Hibernate的持久类和逻辑类。但在启动后页面报错
HTTP Status 500 -
--------------------------------------------
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: net/sf/hibernate/HibernateException
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:272)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
root cause
java.lang.NoClassDefFoundError: net/sf/hibernate/HibernateException
java.lang.Class.getDeclaredConstructors0(Native Method)
java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
JSP代码如下：customer.jsp
<%@ page import= "java.sql.*,java.util.* " errorPage= "error.jsp "%>
<jsp:useBean id= "cm " class= "mypack.Customer " scope= "page ">
<jsp:setProperty name= "cm " property= "* "/>
</jsp:useBean>
<jsp:useBean id= "cb " class= "mypack.CustomerBean " scope= "page "/>
<html> <body> <center>
<%
try
{
if(cm.getId().equals(null)||cm.getId().equals( " "));
else cb.addCourse(course);
%>
成功添加了Customer： <br>
username： <%=cm.getUsername()%>
Id: <%=cm.getId()%>
<%
}
catch(Exception e)
{
}
%>
<hr>
<br> ::增加一个Customer:: <br>
<form action= "customer.jsp " method= "get " name= "add ">
id: <input type=text name= "id "> <br>
username: <input type=text name= "username "> <br>
<input type=submit value= "submit "> <br>
</form>
<hr>
::按名字模糊查找:: <br>
<form action= "queryCustomer.jsp " method= "get " name= "queryByName ">
username: <input type=text name= "username "> <br>
<input type=submit value= "query "> <br>
</form>
<hr>
::删除一个Customer:: <br>
<form action= "deleteCustomer.jsp " method= "get " name= "queryByName ">
id: <input type=text name= "id "> <br>
<input type=submit value= "delete "> <br>
</form>
<hr>
<a href=viewAll.jsp> ::查看所有Customer:: <a>
</body>
</html>
HIBERNATE业务逻辑代码如下：
package mypack;
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;
import java.util.*;
/**
*和Customer相关的业务逻辑
*/
public class CustomerBean extends HibernateBase
{
public CustomerBean()throws HibernateException
{
super();
}
/**
*增加一个Customer
*/
public void addCustomer(Customer st)throws HibernateException
{
beginTransaction();
session.save(st);
endTransaction(true);
}
/**
*查询系统中所有的Customer，返回的是包含有Customer持久对象的Iterator。
*/
public Iterator getAllCustomer()throws HibernateException
{
String queryString = "select Customer from Customer as Customer ";
beginTransaction();
Query query = session.createQuery(queryString);
Iterator it= query.iterate();
return it;
}
/**
*删除给定ID的Customer
*/
public void deleteCustomer(String id)throws HibernateException
{
beginTransaction();
Customer Customer=(Customer)session.load(Customer.class,id);
session.delete(Customer);
endTransaction(true);
}
/**
*按Customer的名字进行模糊查找，返回的是包含有Customer持久对象的Iterator。
*/
public Iterator getSomeCustomer(String name)throws HibernateException
{
String queryString = "select c from Customer as c where c.username like :username " ;
beginTransaction();
Query query = session.createQuery(queryString);
query.setString( "username ", "% "+name+ "% ");
Iterator it= query.iterate();
return it;
}
}
请各位同志帮忙看下

司法
[解决办法]
net/sf/hibernate/HibernateException
应该是少了某些类吧
[解决办法]
类没找到，应该是你想classpath添加的jar文件没成功，好好检查检查，另外查看你的hibernate的jar文件文件中是否有net/sf/hibernate/HibernateException这个类，如果没有说明你的hibernate版本不正确
[解决办法]
看看你hibernate的版本。
hibernate3.0:
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate2.0:
hibernate.dialect=net.sf.hibernate.dialect.MySQLDialect
[解决办法]
jar有问题 好好检查
[解决办法]
大侠：你好，我正在学习hibernate，和和一样，练习做网上的一个例子，出的错误也一样
下面是你提问的地方：

我想问你最后解决没？如何解决的？
