Message splitting using java mapping and BPM

Question

Hi all,
I have a PLAIN FILE to IDOC Scenario.
We decide to use javamapping instead of message mapping because we have several hierachical structures.
We has more than one IDOC for file. And the mapping it's unable to detect the another header and create it at XI.
I had seen:
/people/michal.krawczyk2/blog/2005/12/04/xi-idoc-bundling--the-trick-with-the-occurance-change
"XI: IDOC bundling - the "trick" with the occurance change"
But the problem it's we doesn't use mapping programs, so we can't apply to this case.
So now i need to create a BPM scenario for resolve this issue. Anyone knows any example for split the income message and send any idocs to destination?
Thanks in advance,

Answer 1

IT WORKED !!!!
The only thing it's at out code line we must improve it in another way.
For everyone who needs to resolve, i copy the code line of the java mapping program.
The relationship is from the specific mapping for every scenary calling GenToHierMap.
