Mixed configuration - too late bean creation

Hi,
I have to type of configuration:
1) base on annotations:

Code:

---

        @Bean(destroyMethod="close")
        public DataSource dataSource() {
                BasicDataSource dataSource = new BasicDataSource();
                dataSource.setDriverClassName("com.mysql.jdbc.Driver");
                dataSource.setUrl("jdbc:mysql://localhost:3306/test");
                dataSource.setUsername("mysql");
                dataSource.setPassword("");
                return dataSource;
        }

---

2) xml (Spring Security):

Code:

---

      <authentication-manager>
                <authentication-provider>
                        <password-encoder hash="md5">
                                <salt-source user-property="username" /><!-- ref="saltSource" -->
                        </password-encoder>
                        <jdbc-user-service data-source-ref="dataSource" />
                </authentication-provider>
        </authentication-manager>

---

Bean created in annotations configuration: dataSource is not visible for Spring Security.
What is wrong with my code?

It is look like dataSource bean is created too late.
(Every thing is ok while I am using it with JPA - before adding security)

Thanks,
Pawel

Edit:
Ok,
I've messed up with configuration.

Code:

---

<context:component-scan base-package="" />

---

was placed in file with configuration for org.springframework.web.servlet.DispatcherServlet.
I've moved it to correct place and everything is ok!
