Spring beanpostprocessor not working on component scan?

Question

I have many spring beans cookies and don't want to explicitly define each of them in xml. So I sent a component scan route that allows me to do this. This is good, but I just realized that MyBeanPostProcessor is not called for beans loaded using component scan technology. MyBeanPostProcessor is just trying to do some setter injection on these beans. The configuration below just shows the approach I tried that does not work. Any other ideas on how to do setter injection on these beans?

I am using Spring 2.5.5

Thanks Ben

<context:component-scan base-package="us.benanderson" 
        use-default-filters="false" 
        annotation-config="false"
        scope-resolver="us.benanderson.MyScopeResolver"
        name-generator="us.benanderson.MyBeanNameGenerator">
    <context:include-filter type="custom" expression="us.benanderson.MyTypeFilter" />
</context:component-scan>
<bean class="us.benanderson.MyBeanPostProcessor">
    <property name="order" value="500" />
</bean>

, (Spring 2.5.6). , .

Start.java( )

package se.waxwing.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Start {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("se/waxwing/test/Context.xml");
        context.getBean("customBean");
    }
}

        <context:include-filter type="custom" expression="se.waxwing.test.MyTypeFilter" />
    </context:component-scan>

    <bean id="beanProcessor" class="se.waxwing.test.MyBeanPostProcessor" />

</beans>

CustomBean.java( - . MyTypeFilter)

package se.waxwing.test;

public class CustomBean {

    public CustomBean() {
        System.err.println("instantiating component");
    }
}

MyBeanPostProcessor.java

package se.waxwing.test;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;

public class MyBeanPostProcessor implements BeanPostProcessor {

    public MyBeanPostProcessor() {
    }

    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
        System.err.println("after " + beanName);
        return bean;
    }

    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        System.err.println("before " + beanName);
        return bean;
    }   
}

MyScopeResolver.java

package se.waxwing.test;

import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.context.annotation.ScopeMetadata;
import org.springframework.context.annotation.ScopeMetadataResolver;
import org.springframework.context.annotation.ScopedProxyMode;

public class MyScopeResolver implements ScopeMetadataResolver {

    @Override
    public ScopeMetadata resolveScopeMetadata(BeanDefinition definition) {
        ScopeMetadata result = new ScopeMetadata();
        result.setScopedProxyMode(ScopedProxyMode.NO);
        result.setScopeName("prototype");
        return result;
    }

}

MyTypeFilter.java

package se.waxwing.test;

import java.io.IOException;

import org.springframework.core.type.classreading.MetadataReader;
import org.springframework.core.type.classreading.MetadataReaderFactory;

public class MyTypeFilter implements TypeFilter {

    @Override

        return metadataReader.getClassMetadata().getClassName().equals(CustomBean.class.getCanonicalName());
    }
