Hello Julia! 1) Yes, do check you servlet container log files, maybe you'll find anything of interest both to us and you there
2) Find out exactly what is communicated between your browser and your servlet. There are a couple of ways of doing this: - use wget - use org.apache.soap.util.net.TcpTunnerlGui - use TcpTrace.exe for more detailes on getting and using these see http://tagunov.tripod.com/i18n/view.html And please send us what you find out this way! BTW: (for my education) what does those Content-disposition: inline header do? JZ> Richard: JZ> I invoke my servlet via a html file.
