Determine job 'input-path' dynamically at runtime

[saurabhjain27]

What is the recommended approach to determine parameters like input-path & output-path dynamically.
I was trying to set-up them up in the "pre-action" via a Java Callable, and use SPEL in the job configuration to access these dynamic values from the callable bean (defined in pre-action); this does not seem to work. Can you please provide any recommendations.

I think, rather than setting these properties as part of job-runner "pre-action", I should set them up in an independent bean, and depends on "init" to initialize these variables correctly.

That might work or you can register/configure the bean yourself depending on how dynamic you want things to be.
An alternative to XML is to use JavaConfig - gives much better control over all parameters.
If that doesn't work (because things are initialized too early) then handing the registration itself is a good option.
