Re: Fetching images for users: where to put them?
Thanks for your help!
Seems that there isn't a general solution to this...
(Nice tip on checking exist(), I pulled my hair out a few times when I
forgot to create the folders!)

Re: Fetching images for users: where to put them?
In web.xml:
imageReceiver
xxx.ImageReceiver
imagePath
/the/place
And in the servlet:
public void init(ServletConfig servletConfig) throws ServletException{
imagePath = servletConfig.getInitParameter("imagePath");
if (!imagePath.endsWith(File.separator)) imagePath += File.separator
try {
File imageFolder = new File(imagePath);
if (!File.exists()) Util.mkdirRecursive(imagePath);
} catch ... whatever you want to do if something fails
}

Re: Fetching images for users: where to put them?
Turns out getServletContext returns null.
I am using my own tomcat server, so I'm fine with writing files. Except I
haven't been able to figure out a proper way to get the path.
Currently I use "private static String uglyHardcodedPath =
"../webapps/myproject/"", the prepend this to all my filepaths...
Thanks everyone

Fetching images for users: where to put them?
Hello,
I haven't been able to figure this out after spending 3 hours on
Google.
I can fetch an image, but I don't know where to put them.
If I just use "new File("image.jpg")", it will end up in my tomcat
bin/ folder.
Some sugggests to use getServletContext().getRealPath("/"); but it
would block forever at "getServletContext", I don't know why.
What should I do so it will be part of the war, thus clients can
access it via "http://path.to/appname/images/someimage.jpg";?
What is the best practice on this?
Thank you so much.
Sam
