Problems with load time weaving and @Configurable

[mcantrell]

Ack, I need some help. I've gone over the 2.1 documentation (sections 6.8.1 and 6.8.4) several times and I cannot seem to get @Configurable working with load-time-weaving. There has to be something that I'm missing in my configuration but I cannot spot it. If anyone out there would be kind enough to go over my config and see if you can spot anytyhing, I'd be very grateful for the help.


JPA Entity

@Configurable
@Entity
public class StandardMenu extends BaseStandardMenu {
    @Transient
    StandardMenuDao standardMenuDao;
	
    public void setStandardMenuDao(StandardMenuDao standardMenuDao) {
        this.standardMenuDao = standardMenuDao;
    }


    @PrePersist
    @PreUpdate
    void doAudit() {
        if (id != null) {
            StandardMenu menu = standardMenuDao.getById(id);
            audits.add(new StandardMenuAudit(menu));
        }
        modifiedBy = "foo"; // TODO replace with real value
        modifiedDate = new Date();
    }
}

data-context.xml

<context:spring-configured/>
<context:load-time-weaver/>
<bean id="standardMenu" class="com.mycompany.menu.data.model.StandardMenu" scope="prototype">
	<property name="standardMenuDao" ref="standardMenuDao"/>
</bean>
 <bean id="standardMenuDao" class="com.mycompany.menu.data.dao.JpaStandardMenuDaoImpl"/>

META-INF/aop.xml

<!DOCTYPE aspectj PUBLIC
        "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <include within="com.mycompany.menu.data.model.*"/>
    </weaver>
    <aspects>
        <aspect name="org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect"/>
    </aspects>
</aspectj>

Dependencies:

spring-2.1-m3.jar
spring-aspects-2.1-m3.jar
spring-agent-2.1-m3.jar
aspectjweaver-1.5.3.jar
aspectjrjt-1.5.3.jar

In the JPA Entity above, standardMenuDao is always null according to my unit tests.




- edit -

I forgot to mention that I'm starting the jvm with the javaagent:

-javaagent:C:\dev\server\jboss-4.2.1.GA\lib\spring-agent-2.1-m3.jar

I get a nasty exception if I do not:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [sun.misc.Launcher$AppClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar

Have you been able to fix this problem ? I am also getting the same problem using JPA with Hibernate and Spring @Configurable.

In my case I am facing the same error when I try to introduce another aspect of mine along with AnnotationBeanConfigurerAspect in aop.xml. The error that I am getting is as follows :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor#0' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.config.internalTransactionAdvisor': Cannot create inner bean '(inner bean)' of type [org.springframework.transaction.interceptor.TransactionInterceptor] while setting bean property 'transactionInterceptor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)': Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'entityManagerFactory' while setting bean property 'entityManagerFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: org.hibernate.InstantiationException: could not instantiate test objectorg.dg.domain.entity.Project

The moment I remove the aspect entry from aop.xml, it works fine. I am using Spring 2.1 M4. Any help will be appreciated.

And here is the application context xml file :

If you get a chance, can you try with the latest nightly build (20071010-263 or later). I have fixed a bug (http://opensource.atlassian.com/proj...rowse/SPR-3873) that might affect the behavior you are seeing.

With the new snapshot of Spring, I am getting a different error, which may be a bug with AspectJ (not sure though!).

Indeed, it may be a recently fixed AspectJ bug:

see https://bugs.eclipse.org/bugs/show_bug.cgi?id=230134

You may want to try out the latest development build of AspectJ to see if this problem is fixed.

Best Regards,
Larry
