Re: Writing files accessible from a browser

[Li]

Hi,

Here are few steps of achieving it (just tested, and it works):
1. use FileOutputStream or any output streaming object to write a image file
   into the directory
  in Windows, the path string should look like:
"c:\apache_home\httpdocs\images\1.jpg"
  in unix/linux, the path should look like $APACHE_HOME\httpdocs\images\1.jpg"
  (assume, you had defined APACHE_HOME, make sure the images folder
is read/write
  only for the user/group that runs tomcat
2. Make sure apache is on ...
3. in your jsp: use
  e.g. <a href="http://yourdomain/images/1.jpg";>click to view</a>


Wish it helps

Thanks for the answer,
this solution was part of my investigation, and was actually the first
idea I had.
The problem with this approach is I don't know how to access the
/image_dir/ from within my web application.
Maybe using something like
String path = servletContext.getRealPath("/");
String imagePath = path+"../image_dir/"
and use the imagePath to create my images, then in my jsp something like
<request.getContextPath()/../image_dir/image1.jpg>

But I am not sure this approach works in all configurations,
particularly if my webapp is deployed inside a war.

Thanks
Romain
