Urm, the entire point of ClientAbortException (which is a Tomcat class) is to allow Tomcat to know that it shouldn't be logging it. If com.lowagie.text.pdf chooses to log it, well you'll have to take it up with them ;-).
"Allistair Crossley" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Hi, I've seen similar posts from users before on this topic but do not believe I saw a concrete answer. I was streaming a PDF to my browser yesterday when I decided to quickly move to another page in the website and therefore stopping the PDF response stream. When I looked in the logs, I found the following stack trace. The com.lowagie.text.pdf has spotted that this was a Client Abort which it was, but I also noted that it is wrapping up the real error that occured which was a java.net.SocketException: Connection reset by peer: socket write. We have this java.net.SocketException: Connection reset by peer: socket write error in our logs quite often on our production server and I am "guessing" that perhaps users are stopping the response stream somehow, perhaps closing the browser or moving to another page mid-response? In both that case, and in the case of aborting the PDF stream as below, I am not convinced I need to care since it does not impair the server that a user did not bother to receive the full response. Does anyone disagree or have an explanation why such scary stack traces should be output by Tomcat each time a user does not complete receiving their response .. is it perhaps because Tomcat is unable to differentiate between a user closing their browser and some other network problem that I may well want to know about? Thanks, Allistair.
