I don't know why spring 2.5.6 keeps complaining, but I don't have any "orderBy" annotation.

or even when I swap to use lower version spring 2.5.1, it's still complaining:

If I do not use annotation, it works fine. No problem at all,

Everything happened after this

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

        <context:include-filter type="annotation"
            expression="org.springframework.stereotype.Repository"/>
    </context:component-scan>
</beans>

and I am sure my spring is configured properly.

Can anyone tell me what is wrong? How can I fix this?
