How do I fix "BufferedReader cannot be resolved to a type"?

Question

Hello,
I'm writing a jsp page that read one file and output it. The code look like this:
<%
BufferedReader input = new BufferedReader(new FileReader("tech.csv"));
String line = "";
while ((line = input.readLine()) != null) {
   out.println(line);
input.close();
%>and the error it keeps coming up is:
An error occurred at line: 9 in the jsp file: /FirstServlet.jsp
BufferedReader cannot be resolved to a typeWhat's the problem here? (I put the tech.csv file in the same directory as the jsp file)
Btw, I'm using tomcat 6.0.13.
thanks for the help,
ekb

To fix it, you need to import the class java.io.BufferedReader. And probably FileReader as well.
The following page directive in your JSP should fix it.
<%@ page import="java.io.*" %>I'm not sure why you would want to do it like this when you could just use a <jsp:include>, but its your program :-).
Oh, and new File("...") uses the working directory as a base - it knows nothing about the location of the JSP.
Your best bet there is to use the methods of javax.servlet.ServletContext.
either
String filename = application.getRealPath("/pathToMyCSV.csv");
File f = new File (filename)
BufferedReader input = new BufferedReader(new FileReader(f));or
BufferedReader in = new BufferedReader(new InputStreamReader(application.getResourceAsStream("/pathToMyCSV.csv")));Cheers,
