Why don't you just save the request and the response to a file ?
You do not need log4j for that, right ?
DateFormat df = new SimpleDateFormat("yyyyMMdd-HHmmss-S");
String filename = "/tmp/" + df.format(new Date()) + "-request.xml";
FileWriter writer = new FileWriter(filename);
writer.write(request);
writer.close();
If you need to specify the charset use
OutputStreamWriter writer = new OutputStreamWriter(new
FileOutputStream(filename), "UTF-8");

Hi,
I have a process that sends an xml request to an external server and
receives an xml response back. For purposes of debugging, I need to
capture the request and response in separate files but with similar
names so that I can pair them up easily.
Currently I am using James Stauffer's DateFormatFileAppender (very
useful James!!) with the filename set to
'${log4j.log.dir}/'yyyy/MM/dd/'qresponse.'yyyyMMdd-HHmmss-S'.xml' (and
similar for the request) to log each request and response to a
separate file each time. (I do understand that there is potential for
2 requests at the same millisecond, but this is really for debugging
only and not production, so I can pretty much guarantee that won't
happen).
By using the milliseconds in the filename I can get unique requests or
responses, but each request and subsequent response will have slightly
different timestamps. I might get two requests processed before I get
the response back for the first, which makes it slightly difficult to
match them up.
I don't want to log the request and response to the same file, because
then it is no longer a well formed XML document that I can look at in
an XML browser.
Is there some way I can dynamically add something (like my internal
requestid) to the file names at log time such that I can pair the log
files up, without forcefully finding the appender and reconfiguring it
each time (which would be rather slow)?
If all else fails I can add an XML comment to the end of the file via
the pattern layout, but I am looking for something that will help for
scan value in matching the files up.
Thanks
Chris
