Hello,
I have been trying to integrate hibernate 4 multi-tenancy support in our application but I get the below exception on executing an hql query
Code:
java.lang.ArrayIndexOutOfBoundsException: 0
at org.hibernate.jpa.spi.AbstractEntityManagerImpl.resultClassChecking(AbstractEntityManagerImpl.java:362)
at org.hibernate.jpa.spi.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:344)

at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:291)
at com.sun.proxy.$Proxy43.createQuery(Unknown Source)
The hql query is -
Code:
List<Field> fields = entityManager.createQuery("from " + Employee.class.getName() +
" where " + getQueryForInClause("id", ids), Employee.class).getResultList();
On debugging hibernate source, I realize that this is because hibernate's SessionFactory instance does not have any entityPersister instances due to which the hql query does have any translator's.
Is it because the Entity beans are not getting scanned? If so what could be the cause?
The entityFactory spring is declared as below
Code:
<property name="persistenceProviderClass" value="org.hibernate.jpa.HibernatePersistenceProvider"/>
<property name="persistenceXmlLocation" value="/com/software/persistence/persistence.xml"/>
<property name="jpaProperties">
<map>
<entry key="hibernate.id.new_generator_mappings" value="true"/>
<entry key="hibernate.cache.use_second_level_cache" value="false"/>
<entry key="hibernate.dialect" value="com.software.persistence.ExtendedOracle10gDialect"/>
<entry key="hibernate.jdbc.batch_size" value="10"/>
<entry key="hibernate.jdbc.batch_versioned_data" value="true"/>
<entry key="hibernate.jdbc.batch.builder" value="com.software.persistence.OracleBatchBuilder"/>
<entry key="hibernate.multiTenancy" value="DATABASE"/>
<entry key="hibernate.tenant_identifier_resolver"
value="com.software.persistence.MultitenantIdentifierResolver"/>
<entry key="hibernate.multi_tenant_connection_provider"
value-ref="multiTenantConnectionProvider" />
</map>
</property>
Thanks,
Amit.
