Hi Folks
I have a problem when a user downloads a file, my
code works fine when
the user selects save on the box which pops up on
their browser. However
there are problems when the user selects cancel. What
I have is
response.setHeader("Content-Disposition",
"inline; filename=\"" + fileName
+ "\"");
response.setContentLength((int)f.length());
FileInputStream fin;
ServletOutputStream out =
response.getOutputStream();
BufferedInputStream data = new
BufferedInputStream(fin = new
FileInputStream(getFileName()));
byte[] buf = new byte[4 * 1024]; //4kb buffer
int len;
while( ( len = data.read(buf, 0, buf.length)) !=
-1 )
{
out.write(buf, 0, len);
}
to send the user a file. What seems to happen when
this servlet is run
in Tomcat is that tomcat buffers the result of
out.write(). When the
user is prompted to save the file and clicks cancel
download an exception
is thrown. I want to display
an error page, but I have already sent a response, so
when I do
catch(Exception e)
{
PrintWriter out = response.getWriter();
response.setContentType("text/html");
ServletContext context =
getServletContext();
out.println("An error occured. Please
contact the site administrator");
}
I get the exception
2001-07-19 01:29:14 - Ctx( /default ):
IllegalStateException in:
R( /default + servlet/processAccount + null)
OutputStream is already being used for this request
What can I do to handle the case when the user cancels
the download?
Cheers
Tony
