spring app released in OSGi container classloading woes

[kato Kwong]

Hi,

I have a spring application that deploys successfully in a servlet container. When I try to deploy it in a OSGi container (ServiceMix 4) I have trouble loading the application context.

Here is the error I am getting:

Exception in thread "SpringOsgiExtenderThread-47" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaTransactionManager' defined in URL [bundle://706.0:0/META-INF/spring/jpa-balancing-context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean
' to required type 'javax.persistence.EntityManagerFactory' for property 'entityManagerFactory'; nested exception is java.lang.IllegalStateException: Cannot

And here is my context XML:

        <context:load-time-weaver aspectj-weaving="on"/>
	
	<tx:annotation-driven transaction-manager="jpaTransactionManager"/>

	<bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
		<property name="entityManagerFactory" ref="entityManagerFactory" />
	</bean>

	<!-- Entity manager -->
	<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
	
	<bean id="entityManagerFactory" 
		class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
		<property name="dataSource" ref="dataSource"/>
   	</bean>

So I am trying to use the LocalContainerEntityManagerFactoryBean to dynamically create instances of a JPA EntityManagerFactory. I thought I was specifying aspectJ weaving relative to the bundle classloader with:

<context:load-time-weaver aspectj-weaving="on"/>

But perhaps this is not the case?

Any ideas, what I am doing wrong?

Thanks folks.
