Hi all, I managed to solve the problem. The problem was identified as a problem in tomcat-native 1.1.7 and below. The corresponding bug report is: http://issues.apache.org/bugzilla/show_bug.cgi?id=41124
After deploying the latest tomcat-native (1.1.10) at the time of writing this mail, the problem disappears. Thanks to Haroon Rafique for pointing this out. -- Best regards, Ketut Mahaindra (Ito) -----Original Message----- From: MAHAINDRA Ketut [mailto:[EMAIL PROTECTED] Sent: Friday, June 01, 2007 3:42 PM To: users@tomcat.apache.org Subject: Problem with mod_jk / tomcat on file streaming Hello all, I have a problem when using Tomcat 5.5.23 and apache/mod_jk 1.2.23. I have a piece of code that will stream a file when a download request is made by a user. ... response.setContentType("application/octet-stream"); response.setContentLength((int)fDownload.length()); response.setHeader("Content-Disposition", "attachment; filename=\"" + fromFileName + "\""); // read the fromFile and write to output stream FileInputStream fis = new FileInputStream(location + "/" + fromFileName); //$NON-NLS-1$ BufferedOutputStream bos = new BufferedOutputStream(response.getOutputStream()); int iLen =0; byte[] buffer = new byte[4096]; while ((iLen = fis.read(buffer)) != -1) { bos.write(buffer,0,iLen); } fis.close(); bos.close(); ... When the application is accessed directly through Tomcat on port 8080, there is no problem. But when we put apache / mod_jk to provide connection to tomcat, the stream is disconnected prematurely at around 450K with the following exceptions logged in catalina.out.

Or is it a known mod_jk issue ? Or is it perhaps a configuration issue on my side ? -- Best regards, Ketut Mahaindra (Ito) --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
