Legacy integration - tasklet transaction

Hi i am trying to convert a legacy system to spring batch.
possibly i am thinking of having 2 steps for my job configuration.
1. step1 -This step is like pre processing for the job. i am thinking of using a class that implements tasklet interface(org.springframework.batch.core.step.task let). this tasklet needs to make multiple service calls, each service being in its own transaction.I read in documentation that tasklet is already in a transaction initiated by spring batch. how can i disable this transaction?
all these multiple service calls do not need be wrapped in a transaction. if one of them fails, the processing can stop there, and job can end.
2. step 2 -(begins on sucess of step 1) simple step reading rows from database possibly using jdbc reader and process row by row, writes them back to db possibly using a

thanks

for no transaction in a tasklet, this should do the job:

Code:

---

<tasklet ref="someTasklet">
  <transaction-attributes propagation="NEVER"/>                               
</tasklet>

---

thanks Arno
