I am creating a service class using applicationContext.getBean("service",userDetail). userDetail is specific to each request. I want to pass this userDetail to a dao which is injected into service through spring xml config

public class MyServiceImpl 
 private MyDaoImpl dao;
 private UserDetail userDetail;
......


public class MyDaoImpl 
 private UserDetail userDetail;
...... 

/***Main class getting bean reference from spring****/
ApplicationContext context = new ClassPathXmlApplicationContext("spring-context.xml");
MyServiceImpl service = (MyServiceImpl)context.getBean("service", userDetail);
/**userDetail is session specific attribute****/

Question is - how to pass the userDetail which is in service bean to dao bean which is injected

/***spring config where i am stuck*****/
<bean id="service" class = "MyServiceImpl" scope="prototype">
 <constructor-arg name="userDetail" value = ""/>
 <property name="dao" ref="mydao"/>
/**NOT SURE HOW TO PASS userDetail from service bean into myDao bean
either through constructor or property**/
</bean>
<bean id = "mydao" class="MyDaoImpl" scope="prototype">
 <constructor-arg name="userDetail" value = ""/>
</bean>
