Hibernate二级缓存问题

在加入ehcache.xml配置文件时所产生的编译错误异常！

net.sf.ehcache.CacheException: Error configuring from file:/F:/Struts2/Hibernate21/bin/ehcache.xml. Initial cause was Error configuring from input stream. Initial cause was null:5: Element <ehcache> does not allow nested <defaultCatch> elements.

ehcache.xml文件内容：

<?xml version="1.0" encoding="UTF-8"?>

<ehcache>

<diskStore path="d:/ehcache"/>

<defaultCatch maxElementsInMemory="200" eternal="false"

timeToIdleSeconds="50" timeToLiveSeconds="60" overflowToDisk="true"/>

<cache name="com.hibernate.app.Student" maxElementsInMemory="200" eternal="false"

timeToIdleSeconds="50" timeToLiveSeconds="60" overflowToDisk="true"/>

</ehcache>

hibernate.cfg.xml配置：

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

private static SessionFactory sessionFactory;

static {

try {

sessionFactory = new Configuration().configure()

.buildSessionFactory();

}

}

public static void main(String[] args){

try{

stu.setName("zhangsan"+i);

stu.setCardId("1002");

stu.setTeam(team);

team.getStudents().add(stu);

session.save(team);

System.out.println("从数据库中取得数据，将有sql语句生成begin!----------------------------------------");

Session session1 = sessionFactory.openSession();

Transaction tran1 = session1.beginTransaction();

List<Student> list = session.createQuery("From Student s order by s.name asc").list();

for(Student stu : list){

System.out.println(stu.getName());

}

System.out.println("Over!----------------------------------------");

tran1.commit();

Session session2 = sessionFactory.openSession();

Transaction tran2 = session1.beginTransaction();

Student stu1 = (Student)session2.get(Student.class, "4028814d33acdb5b0133acdb5fe7000c");

Student stu2 = (Student)session2.get(Student.class, "4028814d33acdb5b0133acdb5fe7000d");

System.out.println("以下两条为缓存中取得的数据，因为没有sql语句被执行----------------------------------------");

System.out.println(stu1.getName());

System.out.println(stu2.getName());

tran2.commit();

}catch(Exception e){

e.printStackTrace();

if(null != tran){

tran.rollback();

}

}finally{

session.close();

}

}

}

最后万般无赖，我删除ehcache.xml配置文件，编译成功，但是接下来又有了新的问题，就是上边ehcache.xml配置文件所有的设置又该在什么地方设置呢？ 郁闷了，

有遇到此问题的希望可以交流交流。
