Newbie - Complex step dependency

[klch_hk]

Hi,

I'm new to Spring Batch and encountered a difficulty in setting up some steps.

I need a job that spawns 3 flows (let say A,B,C) as the first step. Then, once flow A and B completes, another flow D will be spawned; when flow B and C completes, flow E will be spawned. I'm not quite sure how it should be expressed in the job definition. Please enlighten me.

Any help would be greatly appreciated.

Cheers,
ken

The easiest way would be to wait until C,D is finished before executing E.

Otherwise I guess you could implement a decision and a loop waiting for a signal from B before executing E. The state machine wasnt really designed to handle this use case elegantly (but there are some new features requested for 3.0 that might help).
