I created the directories correctly, copied the code and now does not compile and returns this error. I am compiling by the terminal using javac.

http://pastebin.com/WLaGQit3

package com.example.web;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

    public class BeerSelect  extends HttpServlet {

        public void doPost ( HttpServletRequest request,
            HttpServletResponse response )
            throws IOException , ServletException{

            response.setContentType("text/html");
            PrintWriter out = response.getWriter();
                out.println("Beer Selection Advice <br>");
            String c = request.getParameter("color");
                out.println("<br> Got beer color " + c);

        }
    }

Stacktrace in the terminal:

  • Are you sure that q Servlet-api is on the classpath of your application? It seems not.

  • I don’t know.. how do I know? I set up Classpath in the terminal pointing to the Servlet jar

  • Post the commands you use in the terminal to compile.

The error displayed is because the compiler cannot find and therefore cannot import javax.Servlet, because that jar is inside the web server. To compile properly via command line it is necessary to specify the path to the jar:

javac -classpath .:/caminho/para/o/jar/javax.servlet.jar com/example/web/BeerSelect.java
