Compiler error: cannot find symbol, symbol: class JSPWriter, location:class Converter

Question

I'm new with Java and just trying to compile a class.

import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.tagext.BodyTagSupport;
import javax.servlet.jsp.tagext.BodyContent;
import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.*;


public class Converter extends BodyTagSupport{

    private String _to;

    public String getTo() {
        return _to;
    }   

    public void setTo(String to) {
        _to = to;
    }


    public int doAfterBody(){

    try {
        BodyContent bc = getBodyContent();
        JSPWriter out = bc.getEnclosingWriter();
        double result = 0.0;
        if(_to.equals("F")) {
            result = toFahrenheit(Double.parseDouble(bc.getString()));
        } else {
            result = toKelvin(Double.parseDouble(bc.getString()));  
        }
        out.write("Resultado: " + result);

    } catch(Exception E) {

    }   

        return EVAL_PAGE; //tells servlet container to process rest of JSP page.
    }

    private double toFahrenheit(double c){
        return 32.0 + (c*1.8);
    }

    private double toKelvin(double c){
        return 273.0 + c;
    }

The compiler error is

cannot find symbol, symbol: class JSPWriter, location:class Converter

I don't undertand why I get this error, so please help me out.

I've already added the servlet-api.jar and jsp-api.jar to the CLASSPATH.

as Balusc said.. java is case sensitive. You imported JspWriter but compiler is searching for JSPWriter... did you use JSPWriter as imported class? If so... it's wrong — Angelo Immediata, Dec 30 '15 at 11:13

Java is case sensitive. Change

JSPWriter out = bc.getEnclosingWriter();

to

JspWriter out = bc.getEnclosingWriter();
