Hi !
I've moved the code to a servlet now. The exception no longer occurs
- but the content of my excel-file is still displayed as text.
Currently I do:
response.setContentType(application/vnd.ms-excel);
OutputStream f = response.getOutputStream();
Is this the correct MIME-Type ? that's

Hi !
your example has inspired me to try to return an ms-excel document as
binary-result of a JSP.
I adopted the code previously provided as follows:
%@page import=java.io.BufferedInputStream,
java.io.ObjectOutputStream,java.io.OutputStream,java.io.File%

Your problem stems from (A) you can't call
response.getOutputStream
after you call response.getWriter and (B) all JSPs call
response.getWriter
before they start executing your code. Move the code to a
servlet and you
will be fine.
If you want to see more details about what Randy

i know that it is impossible because of you can not handle an another
outputstream
within jsp.
But this is a very critical for our application design.

Have you thought of using a servlet mapped to the file you are working with
(ie servlet mapping to *.jpg)? I haven't tried it, but in theory (this is
how I would do it if I had to), the servlet would catch the request, access
the info from the db and return the binary data. Since the client

Your JSP needs to output an IMG tag with a 'src' that points back to your
application as another GET that will then
Of course you could try something like
%@page contentType=image/gif
%%@page import=java.io.BufferedInputStream,
java.io.ObjectOutputStream,java.io.OutputStream,java.io.File
%%
OutputStream f = response.getOutputStream();
File logo= new File(tester.gif);
BufferedInputStream bis = new
Have you looked at jspSmartUpload? There is a free version available.

You can do this although it's not very common and I don't know as I
would recommend it.
Caveats:
- HTML 4.0 and up only
- Use object tag instead of img
- Still can't mix text and binary, your raw image data will have to be
converted to base64 or such either on the fly or in store.
