Q1)
I have read the tutorial ...I see they have written down all the beans in the beans.xml except QuizMaster interface
is it a typo ? or really we don't put interface in the beans.xml ?
Q2) what I observe from this example is that one can change the beans.xml file any time and get the desired instance ....its no longer hard coded in the code.
they are saying IoC helps to decouple . Do you call this decoupling when we modify the beans.xml and get the desired instance at any time ?
For example ,
if you write <ref local="springQuizMaster"/>
if you write <ref local="strutsQuizMaster"/>

@objects
>>You could for example define 2 beans of the same class.
glad to know that . I guess that in that case they should be having two different logical Id's.
But anyway , I am on the first chapter now :)
Thanks for clearing the doubts and help to proceed further
@ dravidnsr
I saw those looks ...I have been reading from the 1st link already......I liked the 3rd link ....very concise ...not bulky to get started .....not scary......looks quite ok for the starters .
Thanks for the links
<bean id="springQuizMaster" class="com.vaannila.Spring
<bean id="strutsQuizMaster" class="com.vaannila.Struts
<bean id="quizMasterService" class="com.vaannila.QuizMa
<property name="quizMaster"> <ref local="springQuizMaster"/>
if ur bean call quizMasterService that refer springQuizMaster that call com.vaannila.SpringQuizMas
@ dravidnsr.
I did not find QuizMaster interface in the beans.xml .....though i saw all other beans present there ....so I asked did forget to write down the QuizMaster over there ? was that a typo ? or thats perfectly ok because its not a bean but an interface .
However , Now I understand that only java beans have the provileges to be written down in the beans.xml :) ....no interfaces are allowed.
My second question was , how does it decouple ? what the decouple means here ? is it because we can configure/instantiate any beans in the beans.xml ? is that the decoupling they are trying to say here ? I wanted to get it verified to the meaning of decoupling here .
thanks
no its not a typo, it defines *bean instances*, not classes and interfaces used.
