Hi guys,

I'm using spring, all my annotated entity class information are put in the ApplicationContext.xml. I'm using a MySql database, now how can I use the SchemaExport function in hibernate to create the tables? My application can't create the table automatically, though i have set <prop key="hbm2ddl.auto">create</prop>. This is my ApplicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName" value="com.mysql.jdbc.Driver" />
  <property name="url" value="jdbc:mysql:///edde" />
  <property name="username" value="root" />
  <property name="password" value="" />
 </bean>

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

  <property name="annotatedClasses">

    <value>com.edde.Book</value>
   </list>
  </property>
  <property name="hibernateProperties">
   <props>
    <prop key="current_session_context_class">thread</prop>
    <prop key="show_sql">true</prop>
    <prop key="hbm2ddl.auto">create</prop>
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.use_sql_comments">true</prop>
    <prop key="hibernate.format_sql">true</prop>
   </props>
  </property>
 </bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  <property name="sessionFactory" ref="sessionFactory" />
 </bean>

 <tx:annotation-driven transaction-manager="transactionManager" />

 <bean id="bookDao" class="com.edde.BookDao">
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

 <bean id="bookService" class="com.edde.BookServiceImpl">
  <property name="dao" ref="bookDao"></property>
 </bean>

</beans>

This is my test application:

package com.edde;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

 /**
  * @param args
  */
 public static void main(String[] args) {
  ClassPathXmlApplicationContext factory = new ClassPathXmlApplicationContext("applicationContext.xml");
  BookService service = (BookService) factory.getBean("bookService");

  Book book = new Book();
  book.setBookName("great book");

  service.saveBook(book);

 }

}

When I run my app, I get this error:
