tomcat 5.5/win & loading external image files

[ed...@yahoo.com]

i need to load a bunch of image files located outside my exploded war
file.  for example, say that the images live here 
 
|---c:\myimages
|-----------\app
|-----------------\promotions
|-------------------------\images
 
& my app is under 
 
|---c:\tomcat5.5
|----------\webapps
|--------------------\myapp.  
 
the img links are written out dynamically based on an init-param in the
web.xml & javabeans.   the result is that i can get a valid path to the
image resouce looking at the html, but cannot actually load the image. 
 
does anyone know if that's possible on the windows platform (win2k
server)?  
 
 
thanks

Tomcat cannot serve up files outside the root of the app. To do what you 
want requires a work around that has been discussed and debated on this list 
several times. If this is what you have to have, then write a servlet that 
responds to a pattern setup for the images 
(http://www.yoursite.com/yourapp/imagefiles/mypic.jpg). Map the servlet to 
answer for any /imagefiles/* request. Then have the servlet parse the file 
name, read from disk (the directory you want) and serve the file out in 
response to the request.

Other options include using a database to store the images or putting the 
images in the app. One other suggestion was to have an app just for images.

It really is just what fits your needs the best and the pros and cons of 
each. IE You can't move this app to a Linux box without a rewrite.

A relative link will work if it is inside the web application root. 
    If you want to load external images write a Servlet to which the
path or name of the image file is passed as an argument and the
Servlet reads the file using ServletContext.getResourceAsStream() and
write it to the OutputStream returned by the
response.getOutputStream(). Dont forget to set the appropriate MIME
type for content type.
