Regarding Contructor-arg

[dibakar]

I am very new to spring MVC. Recently i have downloaded the spring security sample and was working on that. The sample defines a Controller "bank" and the corresponding bank-servlet.xml has the following entries
<?xml version="1.0" encoding="UTF-8" ?>
-- <bean name="/listAccounts.html" class="bigbank.web.ListAccounts">
<constructor-arg ref="bankService" />
</bean>
- <bean name="/post.html" class="bigbank.web.PostAccounts">
<constructor-arg ref="bankService" />
</bean>
- <bean id="viewResolver" class="org.springframework.web.servlet.view.Intern alResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>

So far I understand the contructor-arg refer to a bean name bankService. But I dont find any definition of the bean bankervice in the configuraton file. Please tell me, what is wrong in my understanding.
Thanks.

When posting please use [ code][/code ] tags.

There is a hierarchy between application contexts. The bankService is loaded in the ROOT application context (which is loaded by the ContextLoaderListener). The DispatcherServlet named bank uses that as a parent context.

Thanks for the advice

How does the Root application context know which class to be loaded as bankservice.
Thanks again for the help

I suggest you read the reference guide, it explains that quite clearly how everything works.

Instead of trying to first climb the Mount Everest that is Spring Security, first climb Mount Annapurna that is the Spring Framework. For example, write a simple web form app that doesn't use Spring Security.
