Problem with Job and Steps

Hi All

I have to delete all the records from the DB if there is a file at a given path before processing the record of new file else don't delete the record from DB.

if(fileExist){
delete the existing records from a table ABC Then process new file
}
else {
Don't delete the existing records from ABC table.
}

Can any one suggest me some solution how to make my job in different steps.

Below is the piece of code. I am executing my batch through command prompt.

Code:

---

<job id="paymentRecordLoadJob" xmlns="http://www.springframework.org/schema/batch">
       
               
                <step id="paymentRecordLoad" >
                        <tasklet>
                                <chunk reader="paymentRecordReader" writer="paymentRecordWriter"
                          commit-interval="2" skip-limit="10000">
                            <skippable-exception-classes>
                                                <include class="org.springframework.dao.DuplicateKeyException"/>
                                                <include class="com.abc.pq.batch.exception.PaymentRecordProcessingException"/>
                                              </skippable-exception-classes>
                            </chunk>
                        </tasklet>
                </step>
               
</job>

Within this job i have to manage that if else condition.

You could use the conditional support provided by Spring batch. You can have a step to check the if the file exists, the step can return a status based on this. The subsequent steps can be called based on the returned status.
