I have a Java Class UpdateStats in WEB-INF/Classes directory of a dynamic web application.This class has a function writeLog() which writes some logs to a text file.I want this text file to be in webcontent directory.Thus everytime the function is called updates stats are written in that text file. The problem is how to give the path of that text file in webcontent directory from within that function,which resides in WEB-INF/Classes directory.

You can get your webapp root directory from ServletContext:

String path = getServletContext().getRealPath("WEB-INF/../");
File file = new File(path);
String fullPathToYourWebappRoot = file.getCanonicalPath();

Hope this helps.
