Hi all,

I am using VTS 3.5.0.M2 + Spring 3.1.1.release + hibernate 4.1.0.Final, when i start the web bundle that contains the jpa annotated persistent entities, it throws this error (import the right Entity annotation : javax.persistence.Entity):

the "org.hibernate.bundle.hibernate-jpa-bundle" is a osgi-fied hibernate-jpa-api-2.0.

and the spring config file :

	<!-- configure annotated Bean -->

	</bean>


	<bean id="transactionManager"

	<!-- Forwards requests to the "/" resource to the "welcome" view -->
	<mvc:view-controller path="/" view-name="layout" />

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/views/" />
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

and the entity class :

package web.virgo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="person")
public class Person {

	@Id
	@GeneratedValue
	private long id;

	private String name;

	public String getName() {
		return name;
	}

	public void setName(final String name) {
		this.name = name;
	}

}

I guess the problem is the osgi class loader thing when finding the annotated entities while building the session factory. But because the session factory is created by spring, i cannot do anything about the classloader.

Is there anything i missed or i am doing something wrong?
Thank you.

Jay

Hi,

We don't support Spring 3.1.x yet as it requires a newer version of AspectJ and some other changes. The work as been done and will be released in due course but until then you should stay on Spring 3.0.x. You can see the changes in the git repos for the Virgo Kernel and Web layers if you wanted to try them out yourself. I suspect they would fix your problems but until we release them there isn't much we can do.

Chris.

Hi Jay,

Did you overcome the situation. what did you do. cause im also trying to implement a modular java application using spring and hibernate and couldn't resolve the dependencies after adding the hibernate features to the bundle. if you can share you working sample that would be great. And i would like to now how did you add snap bundle dependencies in Virgo.

Thanks a lot.

Rajiv.
