How to autowire byName using interface

Hi ,

This is my interface:

These are my two implementation classes :

And this is my service class :

my Main method :

In my master-quiz.xml file I have written :

<bean id = "springQuizMaster" class =""></bean>
<bean id = "strutsQuizMaster" class = ""></bean>
<bean id = "quizMasterService" class = "" init-method = "init" destroy-method = "destroy" autowire="byName">

When I use :

<constructor-arg ref="springQuizMaster"/> instead of autowire attribute it runs perfect

but while using autowiring it fails.
Can anyone help me out?

You can't autowire here without more information because there are two beans that go with that constructor. Spring has no way to know which bean you want injected. That's why it works when you use the constructor.
