New to Java

Hi,

I need some help with a java program which reads xml files to a specified location, running it on a UNIX machine using Java 1.4.1. I modified the code to include the BufferedReader class, but it keeps complaining about not being able to resolve symbol at line 50 & 53. Any help here would be appreciated, since I'm a newbie.

bash-2.05$ javac outputScript.java
outputScript.java:50: cannot resolve symbol
symbol : constructor InputStreamReader (java.lang.String)
location: class java.io.InputStreamReader
BufferedReader in = new BufferedReader(new InputStreamReader("in"));
^
outputScript.java:53: cannot resolve symbol
symbol : method available ()
location: class java.io.BufferedReader
while (in.available() !=0)


Here's the code:

//package cognos8_3;
import java.io.*;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.File;
