Question

When I run the following code using spring batch I get an exception.

<job id="simpleJob">
  <step id="parentStep">
    <tasklet allow-start-if-complete="true">
      <chunk reader="simpleReader" writer="simpleWriter" commit-interval="3"/>
    </tasklet>
  </step>
   <step id="concreteStep1" parent="parentStep">
    <tasklet start-limit="5">
       <chunk processor="simpleProcessor" commit-interval="2"/>
    </tasklet>
  </step>
</job>

It gives the following exception:

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: The element [concreteStep1] is unreachable

I don’t understand why I am getting this error. I have seen similar code in the spring source. Even this does not work. Please help me out with this.

Parent step should be out of scope. That is:

<job id="simpleJob">
   <step id="concreteStep1" parent="parentStep">
    <tasklet start-limit="5">
       <chunk processor="simpleProcessor" commit-interval="2"/>
    </tasklet>
  </step>
</job>
<step id="parentStep">
  <tasklet allow-start-if-complete="true">
    <chunk reader="simpleReader" writer="simpleWriter" commit-interval="3"/>
  </tasklet>
</step>
