And the rollback() at endDocument() as well (if necessary :). Hum ... In fact the transaction id is the file url. IMHO endDocument is not called if an exeption occure in pipeline.

RE: Free for use: SaveFilesTransformer
Really an intersting idea. But I'd not begin the transaction in setup(). What about startDocument()? And the rollback() at endDocument() as well (if necessary :). Though I guess I would like to manage the transactions independantly altogether. In actions fired with separate urls perhaps? ;-) Drs. G.P.H.

Hi all,
I've build a transactionnal write transformer on top of :
http://jakarta.apache.org/commons/transaction/
Works fine in production.

It is derived from the SourceWritingTransformer (yet

can be used to capture also binary streams and save them to disk.

RE: Free for use: SaveFilesTransformer
Can I ask why we need a simplified SourceWritingTransformer? Ofcourse you can: you just did.. :-) No, I don't think a simplified one is needed, but it is the second use case that is most interesting. Perhaps I should have said that it is *another* SourceWritingTransformer.. :-P Kind regards, Geert Drs. G.P.H.
