I am trying to implement Spring Security 3.0 with remember-me feature.

But i am getting the below exception on starting the tomcat server:

The matching wildcard is strict, but no declaration can be found for element 'remember-me'.

i moved <remember-me> tag inside <http use-expressions="true"> and the above error disappers as follows:

    <http use-expressions="true">     	     
        <intercept-url pattern="/**" access="permitAll" />    	
    	<form-login login-processing-url="/j_spring_security_check" login-page="/jsp/login.jsp" authentication-failure-url="/jsp/login.jsp?login_error=t"/>
        <logout logout-url="/j_spring_security_logout" logout-success-url="/"/>

		<remember-me data-source-ref="inMemDataSource" token-validity-seconds="864000" />
    </http>

but, now i am getting a new error:

Cannot resolve reference to bean 'inMemDataSource'

I am following this site http://www.jeviathon.com/2009/09/spring-security-30-with-active.html to implement remember-me feature in Spring Securtiy. But they have not given any implementation of 'inMemDataSource' bean.

please help me in resolving the error.

After going through http://static.springsource.org/spring-security/site/docs/3.0.x/reference/remember-me.html site. i understand that there are 2 implementations available for enabling remember-me feature. they are TokenBasedRememberMeServices and PersistentTokenBasedRememberMeServices respectively. can anybody please provide me a link or an example of these implementations.
