When setting the hibernate property hibernate.hbm2ddl.auto to 'update' an exception is thrown (see stack trace at bottom).
I also get the same exception if instead I try to use ant to update the database script. An excerpt of my ant script is;
<target name="createDDL">
<hibernatetool destdir="${schema-output}">
<annotationconfiguration configurationfile="${hibernate-config}\hibernate.cfg.xml"/>
<hbm2ddl export="true" update="true" outputfilename="db.ddl"/>
</hibernatetool>
</target>

But if i set the hibernate property hibernate.hbm2ddl.auto to 'create' it work (creates the database).

an except of my xxx-service.xml file is;
<bean
id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

<property name="dataSource">
<ref bean="dataSource"/>
</property>

<property name="configurationClass">
<value>org.hibernate.cfg.AnnotationConfiguration</value>
</property>

<property name="configLocation">
<value>WEB-INF/hibernate.cfg.xml</value>
</property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${database.dialect}</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
