hibernate入门篇之新增功能!

不好意思，xml文件贴错了，补上
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

我按照上面的例子，用eclipes做了一下试验，但是出现了问题，整个提示信息为：

Exception in thread "main"

請問wrong where ?

解決一個又出一個問題??
請問一下... run  出現問題 ,
我用 eclipse 3.0 環境
什麼 JNDI 設定在 ?地方?

資訊: building session factory

是为什么？

倒..............
我运行时出现的错误是:
java.lang.NoClassDefFoundError: org/dom4j/Attribute
at com.javamodel.hibernate.Example.<clinit>(Example.java:39)
Exception in thread "main"

答应过smallduzi兄对他的例子Sqlserver版的细致说明
到现在才整理实是不好意思

写在前面的话：
回看出现过的错误，一般都是缺库文件所导致。附件图是我试出来的最少必需库清单。再不行可以把所有的库都加上。另msSQLJDBCDriver.jar是我把MS提供的三个JAR文件，重新打包成一个JAR。如果不用TangHan插件，可以就加入原来的三个JAR文件。

首先：代码当然是按原来的建立了。

  2 ：
加入所需要的库文件，见下图：

  3 ：

hibernate.properties内容改为（数据库、用户和密码请改为你自己的）：

## SQLServer

hibernate.dialect net.sf.hibernate.dialect.SQLServerDialect
hibernate.connection.driver_class com.microsoft.jdbc.sqlserver.SQLServerDriver
hibernate.connection.username sa
hibernate.connection.password 123
hibernate.connection.url jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=blueRain

到此请查看数据的person表，它已加入一条记录。

最后，看看提示信息可以理解更多hibernate运行的机制。让我们开始hibernate之旅吧

要把lib中的jar文件加入classpath中，就不会出现这样那样的问题了！！！

所要加入的库文件没有显示出来啊,能不能告诉我所需的最小的库文件?我将所有的包都加入了,程序没有问题,不过我觉得这样不是太好(有些没必要的包也加入了);

在最下面的图中就可以看到啊，原我想把图跟在第2点后面的，但不太会排版。

你能不能把它列出来啊?最下面的那张图我看不出用到了哪几个包
