The server is running at http://localhost:1234/
I'
m a little confused over this, since I have the same application running locally on GlassFish/MySQL. All I have done is to swap in the relevant jar files, and change the persistence.xml.
My applicationContext.xml looks as follows :
<context:annotation-config/>
<bean id="clientDao" class="com.jameselsey.salestracker.dao.jpa.JpaDaoClient">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="org.springframework.context.annotation.internalPersistenceAnnotationProcessor"
class="com.jameselsey.salestracker.util.GaeFixInternalPersistenceAnnotationProcessor" />
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
<tx:annotation-driven/>
<bean id="clientService" class="com.jameselsey.salestracker.service.ClientService"/>
</beans>
My JPA DAO looks like this
public class JpaDao extends JpaDaoSupport
{
protected <T> List<T> findAll(Class<T> clazz)
{
return getJpaTemplate().find("select c from " + clazz.getName() + " c");
}
protected <T> T findOne(String jpql, Map params)
{
List<T> results = getJpaTemplate().findByNamedParams(jpql, params);
if(results.isEmpty())
{
return null;
}
if(results.size() > 1)
{
throw new IncorrectResultSizeDataAccessException(1, results.size());
}
return results.get(0);
}
}
And an example implemented method looks like this :
@Override
public Client getClientById(Integer clientId)
{
String jpql = "SELECT c " +
"FROM com.jameselsey.salestracker.domain.Client c " +
"WHERE c.id = " + clientId;
return (Client) getJpaTemplate().find(jpql).get(0);
}
Like I say, this works ok on Glassfish/MySQL, is it possible this error could be a red herring to something else?
