Serving Images not inside the web context nor classpath
I try to include some jpg images that are located outside the
application context and outside the classpath, but they are stored
locally on the harddisk of the servlet container. How can I include this
images in my Tapestry pages.
Copying those images into the context or classpath is not an option. It
would be the easiest, if I had a component that accepts the path and
filename as parameter and then automaticly rendered the result.

public IAsset getImage() {
return new ExternalAsset("/appdata/img/12.jpg");
}
Assuming /var/appdata is accessed via "/appdata" in your web container.

i've got some advice from paul ferraro.
using the custom service to fetch the image from the path you specify.
like the jchart service in the workbench example.
but i havent succed in implementing it, and havent got the time to try
it again,
but maybe that can help you

If you want to do it that way I'd look at the code for the various
IAsset implementations under the Tapestry code, and implement the
interface following those examples. I've done this for dynamic svg
images, excel files and pdf files and it wasn't hard. Since these are
just images of existing mime types you can use the existing asset
service.
I solved this problem another way. I created a seperate web-app called
filesystem. Under this I had a logical directory structure classifying
my assets and then symbolic links pointing to their actual place on the
file system. Then I accessed them as full urls
(http://<machine>/filesystem/image.jgp for example). I found this
solution much more flexible in that I could uncouple the application
from the file system location using the symbolic links.

A little code snippet like this would help me, I think. I do not know
how to fill out the blanks:
public IAssest getImage(){
???
File file = new File ("/var/appdata/img/12.jpg");
???
}
