How to run a job in a main class ?

Hi,

I'm a new spring-batch user, and I'm looking at it to split an heavy process.

I've got a litlle problem, I need to calculate an id, at the beginning of the batch.
Then, I launch the batch, the reader do his job, and the processor starts working.
I want the processor to set a property with the id calculated before..
What's the way to pass parameters from the reader to the processor ?


Thx for your help.
