Hi, I'm experiencing the next problem starting a Spring application which is using Hibernate.

Invocation of init method failed; nested exception is org.hibernate.HibernateException: Missing sequence or table: SMB_SEQ_CARPETAS

My hibernateProperties config are the following:

<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.hbm2ddl.auto">validate</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
</props>
</property>

And the sequence exists in database.

I've seen, looking in Internet, that this problem could be around by changing
<prop key="hibernate.hbm2ddl.auto">validate</prop>

for
<prop key="hibernate.hbm2ddl.auto">update</prop>
or
<prop key="hibernate.hbm2ddl.auto">create</prop>


But.... why?

Thanks in advance,

Jaime.
