Spring batch xmlns xsd schema error

Question

I am developing an application using Spring Batch in eclipse

Error I while starting the server is

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: 
 Error creating bean with name 'notificationController' defined in ServletContext       
 resource [/WEB-INF/springbatch-config.xml]: Cannot create inner bean 
 'com.confluence14.utility.Notifier#72372ef8' of type 
 [com.confluence14.utility.Notifier] while setting constructor argument; 
 nested exception is org.springframework.beans.factory.BeanCreationException: 
 Error creating bean with name 'com.confluence14.utility.Notifier#72372ef8' defined in 
 ServletContext resource [/WEB-INF/springbatch-config.xml]:

 'dispatchMailsJob': Cannot create inner bean '(inner bean)' of type 
 [org.springframework.batch.core.configuration.xml.SimpleFlowFactoryBean] while setting 
 bean property 'flow'; ......and so on.......

My xml file used to config spring batch is

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

            </bean>
        </constructor-arg>
    </bean>
</beans>

Now the problem lies in xmlns part at the top of this config file.

In this config file the last bean I declared notificationController tries to refer the bean named dispatchMailsJob which is the first bean declared above but is unable to recognize it.

I am struck on for days. This is my second project in spring batch and I remember that the same issue consumed days in my first project also. (I now don't have access to the code of my first project)

Kindly help me out with what exactly should I write in the xmlns schema part

The spring related libraries I am using are

Answer 1

Probably you need scope="step" for beans using late-binding (#{jobParameters[...]} for example); spring can't create job bean because it can't resolve batch-related spEL expressions
