I am trying to use a series of processing steps within a pipeline for their
side-effects (eg., writing to a db or calling a web service). I am NOT
interested in the output of these steps -- just that they execute. The
problem is that none of these steps are executing because I am not hooking
up the output of the final step with the output of the pipeline. Why does
OXF regard any unused output as a terminal step in the pipeline, and as a
result NONE of the steps are executed?
Example:
processingStep1
inputS1
outputS1
choose (outputS1)
when (condition)
processingStepForSideEffect1
processingStepForSideEffect2
---> Output from this 2nd step is NEVER USED, but that's OK w/me...
---> The problem is that even though condition is met, my 2 side-effect
---> statements are never called!
---> One hack is to put a sessionSerializer as a last step, but
---> that's a hack...
endWhen
endChoose
processingStep2
--> input taken from outputS1
--> output hooked to pipeline's output
Thanks for your help.
