Hello,
I'm trying to use OpenJPA 1.1.0 with the Spring JPA support within an OSGi
environment.
Here is my Spring configuration:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
lazy-init="false">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter">
<property name="databasePlatform"
value="org.apache.openjpa.jdbc.sql.HSQLDictionary"/>
<property name="showSql" value="true"/>
</bean>
</property>
<property name="loadTimeWeaver">
<bean
class="org.eclipse.equinox.weaving.springweaver.EquinoxAspectsLoadTimeWeaver"/>
</property>
</bean>
I have a strange problem when trying to use the entity manager:
Could not open JPA EntityManager for transaction; nested exception is
<openjpa-1.1.0-r422266:657916 nonfatal general error>
org.apache.openjpa.persistence.PersistenceException: Error extracting class
information from "bundleresource://2/".
It seems that OpenJPA tries to autodetect metadata for JPA entities whereas I
explicitly specify them in the persistent.xml file:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"; version="1.0">
<persistence-unit name="myUnit" transaction-type="RESOURCE_LOCAL">
<class>test.service.jpa.model.Author</class>
<class>test.service.jpa.model.Book</class>
</persistence-unit>
</persistence>
If it's the case, is it possible to desactivate this mechanism?
Thanks very much for your help!
Thierry
