RE: How do I get the absolute path of a file in a directory above WEB-INF directory of my web application?

[Jacob Kjome]

Why would one use normal File IO to attempt an absolute file path to the WEB-INF directory of a webapp? Use what the servlet spec provides for you.

String absolutePath = getServletContext().getRealPath("/WEB-INF");

File file = new File(absolutePath);

Just make sure to check for the absolutePath string being null because it will be in the case where you serve the app directly out of a .war file, which is why you shouldn't use File IO unless you absolutely have to. There are plenty of other ways to read files in a servlet app or a generic Java app which doesn't require File IO. Also, if you say "well, I need this so I can write files within my webapp directory", they I would have to say that you've already made your app highly non-portable.

Peter,

this may help you,

try{
        java.io.File dir1 = new java.io.File ("..\\"); // line 1
        System.out.println ("Current dir : " + dir1.getCanonicalPath());
        String[] contents = dir1.list();
        if(contents != null)
                for(int i=0;i<contents.length;i++)
                        System.out.println ("\n"+contents[i]);
}
catch(Exception e) {
        e.printStackTrace();
}


First try to go to root directory( by adding more ..\\) , from there loop
through the sub directories, find matching file name. Query for the
canonical path for that file, you will get the exact path.

I supplied you part of code, Hope this helps

I don't know offhand how you can do that, but if you want to reach up
above the WEB-INF directory, you can use dot-dot (..).
