[JSP] List directory content within a war-file

[Dark Before Dawn]

Hi there,

I am trying to list files and directories within an war-file i.e 
images/summer2010 images/winter2010. The war-file is deployed on a 
tomcat 7 instance with unpackWARs="false".
Since I have no exposed filesystem getRealPath will return null. So I 
tried to use getResourceAsStream wich works fine for files but not for 
directories.
My other idea was to use getResource and URL/URI to get a java.io.File 
via JNDI. But this file is not a file nor a directory.
Cheers
Darky
Code Snippet:
    // null if unpackWar = false
        String absolute = 
this.getServletConfig().getServletContext().getRealPath("files");
    out.write("Files: " + absolute);

    // jndi
        URL url = 
this.getServletConfig().getServletContext().getResource("files");
    out.write("<br/>" + url.toURI());

    File f = new File("file:" + url.toURI());

    // Both null
    out.write(" isDir: " + f.isDirectory());
    out.write(" isFile: " + f.isFile());

        InputStream is = 
this.getServletConfig().getServletContext().getResourceAsStream("files/1.txt");

    // NPE if directory
        BufferedReader br = new BufferedReader(new InputStreamReader(is));
        String line;
    out.write("<br/>content<br/>");
        while ((line = br.readLine()) != null) {
            // print file content
            out.write(line +"<br/>");
        }
        br.close();
