Hi,
in my DAO i am injecting via Spring:
@PersistenceContext
private EntityManager em;
public void save(WSO wso) {
OpenJPAEntityManager oem = (OpenJPAEntityManager) em;
if (oem.isDetached(wso)) {
em.merge(wso);
} else {
em.persist(wso);
}
}
But the "em" is not compatible with OpenJPAEntityManager, so i get a
ClassCastException. My boostrapping code via Spring looks like this:
<bean id="entityManagerFactory"
class
="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<!--
<property name="loadTimeWeaver">
<bean
class
=
"org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver"/>
</property>
-->
</bean>
And my persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/
persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="punit">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</
provider>
<properties>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema"/>
<property name="openjpa.DetachState" value="fetch-
groups(DetachedStateField=true)"/>
</properties>
</persistence-unit>
</persistence>
So how can i use methods only available in OpenJPAEntityManager? Its
somehow ugly anyway to ask if its detached and then do a merge or
persist. I couldnt remember that this was the case with Kodo.
Thx for ideas.
