Problem with jobParameter in xml configuration file

[Mektoub]

Hi everyone,

I'm facing a strange problem in my spring batch application.
It seems I've made a misoncifugration as I can't use #{jobParameters} in my app since I got this exception :

Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 0): Field or property 'jobParameters' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext'
	at org.springframework.expression.spel.ast.PropertyOrFieldReference.readProperty(PropertyOrFieldReference.java:206)
	at org.springframework.expression.spel.ast.PropertyOrFieldReference.getValueInternal(PropertyOrFieldReference.java:71)

	at org.springframework.context.expression.StandardBeanExpressionResolver.evaluate(StandardBeanExpressionResolver.java:137)
	... 52 more

Is there a special BeanPostProcessor or something to configure to make this work ?

Ok I fount out my mistake.

In the bean declaration, where I was using the jobParameter to set a property, I forgot tu set the attribute scope="step" as in the example below :

<bean id="myReader" class="MyItemReader" scope="step">
	<property name="parameter" value="#{jobParameters['myParameter']}" />
</bean>
