Servlet:
May be it is due to security policy plugged into your servlet engine. But then
you
should get a SecurityException. You can also try ServletContext.getResource,
ServletContext.getResourceAsStream
Java:
I don't get the idea behind the while-loop: As far as i understood it,
it's simply there to substitue '/' with '\', isn't it?
The File class has some fine methods which support you in filesystem
'localisation'. See J2SE doc for File.getAbsolutePath(),
File.getCanonicalPath()
You must be carefull with the later in case of symbolic links on Unix
systems. I recall that we had some problems with it in a past project.
But I think you don't need to bother anyways:
String filepath =
getServletContext().getRealPath("/File/AdminFile/adminInfo.txt");
InputStream is = new FileInputStream(filepath);
should work.
Ok for a disclaimer: I have not tried any of my hints i gave to you, so don't
'call me names' if none of them work :-)
