hibernate入门级问题

[badboy_119]

hibernate.cfg.xml文件内容如下：

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory name="foo">
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:DEMO</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.username">username</property>
<property name="hibernate.connection.password">password</property>
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.use_outer_join">true</property>
<mapping file="web\QuickStart\WEB-INF\classes\org\hibernateTest\com\Member.hbm.xml"></mapping>
</session-factory>
</hibernate-configuration>

＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃＃

运行时报下面异常：

我不知道是什么导致这个错误。但你的hibernate.cfg.xml恐怕有问题
1。你用的是oracle，但dialect却选了HSQLDialect，为什么？
2。mapping file 的路径是以hibernate.cfg.xml所在目录为当前目录。而hibernate.cfg.xml一般会放在WEB-INF\classes下，所以应该是这样的：
<mapping file="org\hibernateTest\com\Member.hbm.xml"></mapping>

<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
下面再增加一个属性试试：
<property name="connection.datasource">java:comp/env/jdbc/你的项目名</property>

Could not bind factory to JNDI
----
很明显的错误，<session-factory name="foo"> 会试图将一个SessionFactory实例以foo为名bind到jndi上，但你的application container不支持jndi帮定。
另外，hibernate.dialect定义错了。
