Lior,
Basically, I think that you need to handle the response by yourself.
For instance, if you want to send an image :
***
RenderedImage rimg = ImageIO.read(new File(img));
OutputStream os = response.getOutputStream(); // <=== get the
response to be able to re-write it
ImageIO.write(rimg, "jpg", os);
os.close();
***
In my example I assumed that the MIME content-type was set to the relevant
value, since you said that your headers were OK. But anyway, here is my
stuff to do so :
***
response.setContentType("image/jpg");
***
But if you want to be able to send a file for the browser to download it, or
to be able to send several different types of data all in one response, you
need a multi-part response :
***
response.setHeader("Content-Disposition", "attachment;filename=\"test.doc\"");
// <=== here
response.setContentType("text/doc");
out = response.getWriter();
out.print("what you wish");
response.setContentType("image/png");
out = response.getWriter();
out.print("what you wish too");
out.close();
***
Be aware that without a multi-part response, you can only set one
content-type. If you try and set it a second time, Tomcat will give you a
(beautiful) exception saying something like (can't remember exactly)
"content-type has already been set".
Here is a list of MIME-types, FYI :
http://plugindoc.mozdev.org/winmime.html
With this technique of multi-part response, you can for instance turn a JSP
to a Word file : you set the response type to .doc and let Tomcat render its
JSP compiled to HTML into it. Then the browser received a .doc file with
regular HTML into it, which word is able to read... et voilà !

2007/7/4, lior grinfeld <[EMAIL PROTECTED]>:
you were right, 10X.
now i am facing yet one more challenge.
i made filter to overwrite the response, i added headers as i want and it
works fine.
now i want to manipulate the content , to do zip or to chunk the data.
i tried to do StreamResponseWrapper that extends
HttpServletResponseWrapper, without success.
any ideas on how to implement it?
10X
