A "cleaner" bridge, if possible, would be to have your existing application output it's contents over HTTP as either just text or preferrable XML. If XML, then just a pipelien with the XML Generator and you got it all: no temporary files, etc.. If the output is a more primitive text format, then just write a custom XSP to digest it and begin your pipeline.
