Hi, I am new at this...

I am trying to display data from a text file to a JSP file and I'm using BufferedReader to do this but having problems getting to the file. Which directory should I put the text file? Should I add anything to web.xml to reference to it? Here is the error I am getting... Any help is appreciated.

5: String line = "";
6: String strOutputDir="";
7: String PriceBookVal="";

The error is that "BufferedReader cannot be resolved to a type". It is caused because you have not imported the corresponding libraries.
Import the libraries in JSP as
<@page import="java.io.BufferedReader">
...
and so on

Also the file can be placed anywhere on the server if you are using absolute filepaths.
If you keep the files within the webapp than you can even access it as,
<%=getServletContext().getRealPath("InputData.txt")%>
