Reading directory in JSP file (Struts 1.3)

[nabbler12999]

Hello,

I want to read a directory. But canRead() gives false. How can I do it?

My code:
[code]
<%
String filename="";
File dir = new File("files");

String[] children = dir.list();

if (children == null) {
        System.out.println("ERROR\t can read:"+dir.canRead());
   // Either dir does not exist or is not a directory
} else {
        Random a = new Random(dir.length());

    filename = children[a.nextInt()];

}

    request.setAttribute("randomfile",filename);

%>
[/code]

Thanks very much
