『提问』Tomcat5+hibernate2+UltraEdit成功!用JBuilder9+hib...

在 Tomcat5.0 + hibernate2.1 + UltraEdit + mysql 环境下运行下面的例子：
http://www.loveunix.net/index.php?showtopic=7804
运行成功！现在我想将此例子用 JBuilder9 + hibernate2.1 + mysql 来运行，服务器用JBuilder9自带的Tomcat4.1  但是总是失败！我用JBuilder9来运行，已经弄了两天了，其间出现过一系列小错误，都已经纠正过来。而且在
JBuilder9 + hibernate2.1 + mysql   和 Tomcat5.0 + hibernate2.1 + UltraEdit + mysql 两种配置下，程序的代码都一模一样，只是配置文件稍有不同！所以问题症结应该在这里。
在 Tomcat5.0 + hibernate2.1 + UltraEdit + mysql  配置下的配置文件分别如下：
tomcat5\conf\server.xml中加了如下语句：

我的分析：
由于出现“/hibernate.cfg.xml not found”错误，所以我就将hibernate.cfg.xml文件也放到WEB-INF\classes\下面，使之与文件WEB-INF\classes\hibernate.properties在JBuilder9下共存，文件内容分别如下：
WEB-INF\classes\hibernate.cfg.xml文件：

        <!-- Mapping files -->
        <mapping resource="Course.hbm.xml"/>
       

    </session-factory>

WEB-INF\classes\hibernate.properties文件：

我觉得问题应该出现在两个地方：
1）在 Tomcat5.0 + hibernate2.1 + UltraEdit + mysql 配置下，在tomcat5\conf\server.xml 中要加一些语句，比如数据库驱动相关配置项，如下：

<parameter>
            <name>driverClassName</name><value>org.gjt.mm.mysql.Driver</value>
        </parameter>
        <parameter>
            <name>username</name>
            <value>root</value>
        </parameter>
        <parameter>
            <name>password</name>
            <value>yang900</value>

</parameter>

而这些语句在 JBuilder9 + hibernate2.1 + mysql 下的文件hibernate.properties中基本都有对应项，例如上面的语句在hibernate.properties对应为：

## MySQL

#hibernate.dialect net.sf.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class org.gjt.mm.mysql.Driver
hibernate.connection.url jdbc:mysql://localhost/test
hibernate.connection.username root
hibernate.connection.password yang900

但是如下项在文件hibernate.properties中是没有对应项的：

<Context path="/hibernate" docBase="hibernate">
    <Resource name="jdbc/hibernate" scope="Shareable" type="javax.sql.DataSource"/>
    <ResourceParams name="jdbc/hibernate">
        <parameter>

又由于JBuilder9下的Tomcat和单独运行Tomcat机制不一样，所以不能在JBuilder9自带的Tomcat4.1\conf\server.xml中加入相关配置项。我认为这是主要问题。
2）是文件 hibernate.properties 和文件 hibernate.cfg.xml 之间的区别：
hibernate.cfg.xml文件中有如下项：

<mapping resource="Course.hbm.xml"/>

而在文件 hibernate.properties 中没有对应项。

另：肯定不是Tomcat版本的问题，因为我在
Tomcat5.0 + hibernate2.1 + UltraEdit + mysql
Tomcat4.1 + hibernate2.1 + UltraEdit + mysql
两钟配置下运行此例都成功！



诚请各位大侠帮我解答，本人感激不尽！！！

问题很明显啊，你的datasource设错了。我从未用过Jbuilder，但是问题肯定在这一行：

WEB-INF\classes\hibernate.cfg.xml文件：

        <property name="connection.datasource">java:comp/env/jdbc/hibernate</property> 

试着把其中的内容换成你真正的datasource name，比如jdbc/hibernate，再试。

不是这个问题，我按你说的改了，也不好使。后来，我改了两处：
1）在配置文件hibernate.properties中将

hibernate.connection.datasource java:comp/env/jdbc/hibernate

注释掉.
2）将HibernateBase.java文件中的

sessionFactory = new Configuration();.configure();.buildSessionFactory();;

改为

sessionFactory = new Configuration();.buildSessionFactory();;

结果能运行了，但是不能成功插入数据，也不出现错误，服务器信息如下：

需要在ＪＢ中配置一个DataSource类似在Server.xml中的有关配置一样，不过在ＪＢ　中需要一个mod.jar文件，如果需要，留下你的MSN我可以传给你
