第一个hibernate实例发现对象的配置文件（Customer.hbm.xml ）找不到？
我用的是jb9，hibernate2.1
我把所要用到的文件都放到了，jb9下我建的工程下的src里去了，具体路径是：
E:\java\JB9\TestHinernate\src\com\test\hibernate，下面有四个文件分别为：
Customer.hbm.xml：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="Customer" table="CUSTOMER">
<id name="id" column="CID">
<generator class="increment" />
</id>
<property name="username" column="USERNAME" />
<property name="password" column="PASSWORD" />
</class>
</hibernate-mapping>
hibernate.cfg.xml：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory name="java:comp/env/hibernate/SessionFactory">
<property name="hibernate.connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=test</property>
<property name="hibernate.connection.username">sa</property>

<property name="jdbc.use_scrollable_resultset">false</property>
<property name="hibernate.show_sql">false</property>
<property name="hibernate.cache.use_query_cache">true</property>
<property name="use_outer_join">true</property>
<!-- Mapping files -->
<mapping resource="E:/java/JB9/TestHinernate/src/com/test/hibernate/Customer.hbm.xml"/>
</session-factory>
<!---->
</hibernate-configuration>
Customer.java：
这个文件就是一些个set,get方法，
Test.java：
package com.test.hibernate;
import java.io.File;
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;
public class Test {
public static void main(String[] args) {
try {
SessionFactory sf = new Configuration().configure(new File("E:/java/JB9/TestHinernate/src/com/test/hibernate/hibernate.cfg.xml")).buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
for (int i = 0; i < 200; i++) {
Customer customer = new Customer();
customer.setUsername("customer" + i);
customer.setPassword("customer");
session.save(customer);
}
tx.commit();
session.close();
} catch (HibernateException e) {
e.printStackTrace();
}
}
}
运行Test.java错误提示为：
net.sf.hibernate.MappingException: Resource: E:/java/JB9/TestHinernate/src/com/test/hibernate/Customer.hbm.xml not found

实在在找不到解决的办法，请大家帮帮我。

config文件中不能用绝对路径，要用类路径：com/test/hibernate/Customer.hbm.xmlTop

Customer.CLASS 没有找到
你确定你的Customer.CLASS 文件和Customer.hbm.xml文件 放在com/test/hibernate/文件夹下吗?Top

<class name="Customer" table="CUSTOMER">
如果这个类在包里的话.要加上包的路径.

我的问题OK了，主要有两个原因，一：<class name="Customer" table="CUSTOMER">我应该加上包的路径；二：config文件中不能用绝对路径，要用类路径。
谢谢大家认真看了我的程序，真的很感谢啊！祝你们身体健康！！Top
