Mixed configuration - too late bean creation

[slowikps]

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

        @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):

       <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.

<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!
