I have a servlet that recieves data from a client. All the servlet is doing is reading
from the InputStream of the HttpServletResponse (BufferedReader br = new
BufferedReader( new InputStreamReader(request.getInputStream()));) and writing the
data to a disk file.
Periodically Tomcat refuses to read the data and dumps with an IOException (attached
below). I've googled for the error message but all I can find is references to CVS
versions of the AJP13 code - which puts me out of my depth. I can't find any reference
to the error message in the list archives.
The "odd" thing is this seems to be related to the size of the data stream. The data
is actually an Order Confirmation and when the order contains five lines at 7745 bytes
everything works OK. When the order contains 6 lines (or more) at 8862 bytes then I
get the dump. It's not related to the data content - I've tested this by using known
good data.
I'm using Tomcat 4.1.7-LE-jdk14 - upgrading is an option, but not one I will be able
to undertake lightly.
Regards
Roger
