java - Inheritance in spring batch not working as intended -


when run following code using spring batch 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 following exception:

exception in thread "main" org.springframework.beans.factory.parsing.beandefinitionparsingexception: configuration problem: element [concretestep1] unreachable

i don't understand why getting error. have seen similar code in spring source. not work. please me out this.

parent step should out of scope. 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>
