I get an error when I want initialize an instance of class SpringComponent by Spring Bean Factory

[Garriot Zhang]

I want to use restlet with Spring framework and I want Spring can help me to 
initialize all the object I needed. 

So I wrote a beans definition file as the following:

<?xml version="1.0" encoding="UTF-8"?>
<beans>

 <bean id="component" class="org.restlet.ext.spring.SpringComponent">
        <property name="server" ref="server" />
        <property name="clients">
                <list>
                        <value>file</value>
                </list>
        </property>
 </bean>
   
 <bean id="server" class="org.restlet.ext.spring.SpringServer">
      <constructor-arg value="http" />
      <constructor-arg value="8182" />
 </bean>

</beans>

Before I use the spring component, I want to define the server and client 
properties that are needed in the future. 

I wrote a test method for this file:

        public static void main(String[] args) {
                try {
                        Resource resource = new ClassPathResource("beans.xml");
                        XmlBeanFactory beanFactory = new XmlBeanFactory
(resource);
                        SpringComponent component = (SpringComponent) 
beanFactory
                                        .getBean("component");
                        component.start();
                } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }
        }

But When I ran this method I got an error as "Failed to convert property value 
of type [java.util.ArrayList] to required type [org.restlet.util.ClientList] 
for property 'clients'".

I checked the source code of SpringComponent. I finded two setters fot clients 
property. One is setClients(List<Object> clients) and another is setClients
(ClientList clients), which is inherited from class Component. I think Spring 
called a wrong method when it tried to set clients property.

I tried servral ways to fix it but failed.
How can I resolve this problem? 

Thanks a lot.
