DataSource not injected to @Resource annotated field with alwaysUseJndiLookup setting

I've just read about @Resource annotation from this article (http://www.infoq.com/articles/spring-2.5-part-1) and wish to use it on Tomcat 6.0.26 and Spring 3.0.3

But it does not work -- field ds in Users class does not initialized and I've got NullPointerException when I try to made a query.

File src/org/example/db/Users.java

package org.example.db;
import javax.sql.DataSource;
import javax.annotation.Resource;

@Repository
public class Users {

 @Resource private DataSource ds;
 ...
}

I don't know why it does not work. I found in documentation this:

NOTE: A default CommonAnnotationBeanPostProcessor will be registered by the "context:annotation-config" and "context:component-scan" XML tags. Remove or turn off the default annotation configuration there if you intend to specify a custom CommonAnnotationBeanPostProcessor bean definition!

I think it may be about my problem, but in this case I don't know how to "Remove or turn off the default annotation configuration".

Please help. Thanks in advance!

Solution

For now this issue is resolved.

All this code works, but I think the problem was in some of the related classes. For example, I have following autowiring hierarchy: dataSource injects to Users class, Users class injects to Validator, Validator is called from Controller. In this chain were a few bugs:

Users are created using a new Validator instance
after @Autowiring propagation, User did not inject to Validator because this class was in another package and component-scan not find it
later User did not inject to Validator because this class does not have @Component annotation
Controller creates new instance of Validator using the default constructor

After I resolve all these issues all works fine.
