映射文件創建簡單的Hibernate應用程序我得到錯誤： -

<?xml version='1.0' encoding='UTF-8'?> 
<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping> 
    <class name="hibernate.Employee" table="emp1000"> 
    <id name="id"> 
    <generator class="assigned"></generator> 
    </id> 

    <property name="firstName"></property> 
    <property name="lastName"></property> 

    </class> 

</hibernate-mapping>
