Hibernate 可编程配问题?100分
Configuration cfg = new Configuration()
.addFile( "CcCifNgtvInfo.hbm.xml ");
SessionFactory sessions = cfg.buildSessionFactory();//到这里抛出异常
Session sess = sessions.openSession(conn);//程序已有的连接
输出信息:

[解决办法]
Hibernate Dialect must be explicitly set
就是说你hibernate方言没设正确 检查你的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-3.0.dtd ">
<hibernate-configuration>
<session-factory>
<!-- datasource connection properties -->
<property name= "connection.datasource ">
java:comp/env/jdbc/arts
</property>
<!-- dialect for Mysql (InnoDB) -->
<property name= "dialect ">
org.hibernate.dialect.MySQLInnoDBDialect
</property>
<property name= "hibernate.show_sql "> false </property>
<property name= "hibernate.transaction.factory_class ">
org.hibernate.transaction.JDBCTransactionFactory
</property>
<!-- mapping files -->
<property name= "jndi.url "> jdbc:mysql://localhost/arts </property>
<mapping resource= "Smallclass.hbm.xml " />
</session-factory>
</hibernate-configuration>
这里给你举一个例子 注意 <property name= "dialect ">
org.hibernate.dialect.MySQLInnoDBDialect
</property>
[解决办法]

[解决办法]
CcCifNgtvInfo.hbm.xml文件需要路径
File file = new File( "c:\\CcCifNgtvInfo.hbm.xml ");
Configuration config = new Configuration.configure(file);
[解决办法]
可能是你的hibernate.properties文件中没有设置dialect
[解决办法]
也有楼上面说的dialect 我是从错误提示上看的
[解决办法]
应该加载你的hibernate配置文件吧，你怎么加载的是映射文件呢，
[解决办法]
顶一个
[解决办法]
不懂，
up
[解决办法]
这样加载映射文件肯定是不行的.Configuration cfg = new Configuration()本身就是设置加载配置文件的,而你的映射文件里没有任何于配置相关的项.
hibernate是通过配置文件来设置session,然后通过session根据映射文件去操作数据库.你这么做根本就是反过来了.通过映射文件去设置session,然后session再反过来操作映射文件,这样这么可能对呢.
总之,hibernate不是你这么用地
[解决办法]
你的问题应该不是太大，从打印来看，可能是配置有问题，具体情况要你自己看了，
按照freedom2001(天翔) 说得，你在仔细看看，把原理弄懂就好了，
[解决办法]
配置文件的问题，检查hibernate.cfg.xml、xxx.hbm.xml等文件
在程序中直接这样写就ok了，SessionFactory sf = new Configuration().buildSessionFactory();
[解决办法]
如果不想用hibernate，而直接采用jdbc方式连接数据库的话，那需要你自己写获得数据库连接的代码
[解决办法]
不管你的连接是哪里的,您得给一个方言的配置,配置的属性文件是得有的啊
