  } 
} 

以上代码用的是斑竹的例子

我估计是xml出问题：

<?xml version="1.0" encoding="GB2312"?> 
<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" > 
<hibernate-mapping> 

  <class name="hiberante.PersonModel" 
         table="ZY_PERSON"> 
    
    <!--hibernate为我们生成主键id--> 
    <id name="id" type="long"> 
      <generator class="sequence"> 
        <param name="sequence">ZY_PERSON_ID_SEQ</param> 
      </generator> 
    </id> 

    <property name="name"/> 
    <property name="address"/> 
    
  </class> 
</hibernate-mapping> 

警告: No dialect set - using GenericDialect: The dialect was not set. Set the property hibernate.dialect.
是为什么？

hibernate.properties not found

是为什么？
我把hibernate.properties放到了classes下了

<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>

注意看hibernate的文档,Dialect节说得很清楚.
