Constructor signature and spring-core

[belaran]

Hi,

I got a class XmlDAo that implement IPersonDAO ok ?

public class XmlDao implements IPersonDAO

I got another class that recevied a IPersonDAO as a an argument, at build

public PhoneBookImpl(IPersonDAO dao)

So i wrote this in my config.xml file :

<bean id="phoneBook" class="com.ao.springframework.webflow.samples.phonebook.doa.PhoneBookImpl">
			<constructor-arg><ref bean="XmlDao"/></constructor-arg>
		</bean>

But at runtime, i have this error :

Error creating bean with name 'phoneBook' defined in class path resource
[org/springframework/webflow/samples/phonebook/deploy/service-layer.xml]:
1 constructor arguments specified but no matching constructor found in bean 'phoneBook' (hint: specify index arguments for simple parameters to avoid type ambiguities)
at org.springframework.beans.factory.support.Abstract AutowireCapableBeanFactory.autowireConstructor(Abs tractAutowireCapableBeanFactory.java:576)
at org.springframework.beans.factory.support.Abstract AutowireCapableBeanFactory.createBean(AbstractAuto wireCapableBeanFactory.java:312)

XmlDao implements IPersonDAO so it should work, shouldn't it ?

Did I miss something, somewhere ?

Try:
<constructor-arg index="0">
