I am using NES as the webserver. Is any specific setting required in NES, so that
it allows the servlet running in weblogic to download the files after changing
the content type.
This is a discussion on Download attempt from servlet, returns "The page cannot be displayed". - Weblogic ; Hello, we have a JSP which displays a report, and has a "download" gif, cliking on which, the form is submitted to a servlet, which is supposed to download the report as a xls file.

Hello, we have a JSP which displays a report, and has a "download" gif, cliking
on which, the form is submitted to a servlet, which is supposed to download the
report as a xls file.
Note that, no data file actually exists on the server, the servlet will fetch
the data from database and stream it to client when download is clicked.
The servlet code looks something like:
//******* start code
response.setHeader("Cache-Control","no-cache");//HTTP 1.1
response.setHeader("Pragma","no-cache");//HTTP 1.0
response.setDateHeader ("Expires", 0);//prevents caching at the proxy server
String strFileName = "Test.xls";
response.setHeader("Content-Disposition", "attachment; filename=\"" + strFileName
+ "\";");
response.setContentType("application/vnd.ms-excel");
javax.servlet.ServletOutputStream outStream = null; outStream = response.getOutputStream();
outStream.println("Modules Report: Breakdown by Region/Branch"); outStream.flush();
outStream.close();
//******* end code
But it does not download and instead give a "The Page cannot be displayed" error
page.
Why does this happen? If the setContentType code is removed, it pops up the dialogue
box whihc has the open/save to disk option.
Client is IE 5.5 on windows 2000 workstation
Server is weblogic 6.1 on solaris 7
Thanks...

I find these errors in the NES errors log, when I try to access the servlet whihc
is supposed to do the download.
'PROTOCOL_ERROR [line 651 of URL.cpp]: malformed header: LF doesn't follow CR'
I'm getting this error from weblogic plug-in proxy on UNIX(Solaris). It work fine
for NT environment/ I'mm using NES server 3.6.
The servlet is returning a downloaded page in the HttpServletResponse. The content-type
is set to "application/x-excel" before setting the response content.
