我是用3.0里头的例子做的啊：
<?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>
<property name="connection.datasource">java:comp/env/jdbc/OracleDS</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>

<mapping resource="Cat.hbm.xml"/>
－－－－－－－－－－－－－这里的xml文件放在哪儿目录？是classes目录吗？－－－－
</session-factory>

</hibernate-configuration>

package org.hibernate.examples.quickstart;

public class Cat {

private String id;
private String name;
private char sex;
private float weight;

public Cat() {
}

public String getId() {
return id;
}

private void setId(String id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public char getSex() {
return sex;
}

public void setSex(char sex) {
this.sex = sex;
}

public float getWeight() {
return weight;
}

public void setWeight(float weight) {
this.weight = weight;
}

}
