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)

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 &n
