Auto generate tables

I am new in use OpenJPA. By default auto generation tables in database is
enabled, but i have to disable it because openJPA offers to generate table
which exists in database. How can I do that?

Please.

:) Excuse me. I pasted wrong bean. I use:

<bean class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter"> 
         <property name="showSql" value="true"/> 
         <property name="generateDdl" value="true"/> 
</bean>

:-)  FYI, based on the configuration posted, you are using the TopLink JPA
provider, not the OpenJPA provider...

Hi Kevin,

I found a problem. I use OpenJPA with Spring framework and have bean:

 <bean id="entityManagerFactory"
class="org.springframework.orm.jpa.ContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="jpaVendorAdapter">
      <bean
class="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter">
        <property name="showSql" value="true"/>
        <property name="generateDdl" value="true"/>
        <property name="databasePlatform"
value="oracle.toplink.essentials.platform.database.HSQLPlatform"/>
      </bean>
    </property>
    <property name="loadTimeWeaver">
      <bean
class="org.springframework.instrument.classloading.SimpleLoadTimeWeaver"/>
    </property>
  </bean>

I only set property "generateDdl" to true and all working fine now.

Thanks.

Hi hesp,
You don't mention which release, so I will just use the 2.0.x (trunk)
version of the documentation.  You can access other documentation releases
as well [2].

The forward runtime synchronization is documented here [1].  The interesting
thing is that this is not turned on by default.  So, I'm wondering how you
are getting this capability by default.  Unless you are running with a
persistence.xml file that just happens to have this SynchronizeMappings
property set?
