hi andrew,
when you give only the file name, tomcat does not use your application
directory to access it. it uses it's own installation directory. so
you must use the exact path of the file or use ServletContext as i
mentioned abow.
shortly you must do fallowing:
for reading the file:
ServletContext sc = this.getServletConfig().getServletContext();
InputStream is = sc.getResourceAsStream("/blabla.txt");
BufferedReader input = new BufferedReader(new
InputStreamReader(is));
then you can acces your file correctly.
while wrting the file:
ServletContext sc = this.getServletConfig().getServletContext();
BufferedWriter out = new BufferedWriter(new
FileWriter(sc.getRealPath("/blabla.txt")));
if you are using linux, tomcat user must have read and write rights of
the file.
good luck
