It looks like they were already including the SYSTEM_DATE in the name, per the original note. In my experience, using a datestamp is not sufficient to be unique in these kinds of cases, unless the volume is exceedingly low. Instead, you need something like a request number to go with, or a process to check for the existence of the file ahead of time or after an exception creating it.

Try using the following snippet as the iterate target; <target> <sequence> <header name="To" action="set" expression="fn:concat('file:',fn:concat(get-property('SYSTEM_DATE','yyMMddHHmmssSSS'),'_response.xml'))"/> <send/> </sequence> </target> Note that I have removed the endpoint from the target and added a send to the sequence. You might want to prefix the directory path where you want to save the splitted files too, in which case add that path after the 'file:' part of the first concat xpath expression. I hope this will be of some help for you :-) Ruwan On Tue, Aug 2, 2011 at 7:15 PM, De Vleeschauwer Nele < [email protected]> wrote: > I've just created a proxy service which receives a given xml files, > splits it and writes the different parts to disk.
