Spring constructor injection error

I am getting the following error for a bean in my application context:

Here is my bean:

<bean id="businessLogicContext" class="org.springframework.context.support.ClassPathXmlApplicationContext" depends-on="resolveProperty">
         <constructor-arg index="0">
            <list>
               <value>jms-applicationContext.xml</value>
               <value>jms-managerBeanContext.xml</value>
               <value>jms-daoContext.xml</value>
               <value>jms-serviceContext.xml</value>
          </list>       
         </constructor-arg>
    </bean>

I don't know what's wrong, I have googled how to inject a string array via constructor injection and the way I do it above seems okay.

The constructor expects a String or String[] type and you're attempting to inject an ArrayList.

Make it like this

<bean id="businessLogicContext" class="org.springframework.context.support.ClassPathXmlApplicationContext" depends-on="resolveProperty">
         <constructor-arg>
            <list>
               <value>jms-applicationContext.xml</value>
               <value>jms-managerBeanContext.xml</value>
               <value>jms-daoContext.xml</value>
               <value>jms-serviceContext.xml</value>
          </list>       
         </constructor-arg>
    </bean>    

Check the constructor doc It accepts array of String, which can be injected using <list>

You can try this:

<bean id="businessLogicContext" class="org.springframework.context.support.ClassPathXmlApplicationContext" depends-on="resolveProperty">
   <constructor-arg value="jms-applicationContext.xml,jms-managerBeanContext.xml,jms-daoContext.xml,jms-serviceContext.xml"/>
</bean>

I accidentally overwrote a certain jar --- xbean.jar with a different version from the one I was previously using.

So when I compiled my jar with this different version as dependency and ran it it was giving me this error. It's working now. hehe.
