Subject RE: OutputStream Already in USE ..!!!!

Usually, you don't set the Content-Length because that's generated pages,
and if you set a Content-Length higher than the real size of the generated
gif, I don't know how IE or Netscape will react... But you can try it. I
think you just have to set the Content-Length the same way you set the
Content-Type.

Hope that'll help.

Thanks Benoit  and  Michael

It works in Netscape.

But one more strange problem has arrived.
If the Size of the graph ( image ) is less..approximately less than 5k or
so...
The same problem persists..(ASCII Characters output).
So how to set the content length..? since i don't know the content length of
the graph image generated by the GIF encoder.
Please help again.

Thanks for the time.
Regards..

I don't know why you get a OutputStream already in use, but the reason why
it works with IE and not with Netscape may be because you do not set
properly the Content-type of your image. Indeed, IE seems to be a little bit
cleverer than Netscape because it interprets the real content of a file
before displaying it instead of only looking at the Content-type header
property. So you have to be more explicit with Netscape.

 I am using Tomcat and trying to write a Gif file to client browser window
using JSP.
I use ACME - GifEncoder to convert the picture to GIF.
The Encoder needs OutputStream type object as one of the parameter in its
constructor.
I am using ServletOutputStream object for this, which i got through
response.getOutputStream().

But the tomcat gives Error as "OutputStream already been used."

But the GIF image is Displayed properly in IE 5.0.

It gives ASCII charactes in Netscape.

Why is this so.

Please help.
Thanks for the time.

Regards.
