Hi Stefan
Yes, the module is only executed once. Once it is completed, then message processing moves to the next module in the chain. I don't think it's possible for one module to pass data into the next module and still be in a waiting state.
Regarding creating child messages, I am not familiar how to achieve this in an adapter module. I've looked through the JavaDocs for the adapter framework and can't find any such methods. However, I do know that Seeburger's BIC module bean has the capability to split a message into multiple child messages and send those messages back into the Inegration engine via a Split997 channel. Unfortunately I do not have access a system with Seeburger now to use the following technique to get and study the BIC module bean source code.
Get your hands on those (precious) module source code!
Maybe there are other alternatives to achieving your requirement, i.e. multi-mapping, Java mapping, BPM, etc. Can you elaborate the reasoning behind splitting the file every N lines? Also, after the split has been completed on the sender side, does it need to be recombined at the receiver side? Will the file adapter's chunk mode fulfill your requirement?
