编译servlet时找不到符号

Question

这是我的servlet代码：

    package com.example.web;
    import javax.servlet.*;
    import javax.servlet.http.*;
    import java.io.*;
    import java.io.IOException;
    public class BeerSelect extends HttpServlet{
      public void doPost(HttpServletRequest request,
          HttpServletResponse response) 
          throws IOExcpetion, ServletException{
        response.setContentType("text/html");
        PrintWriter  out = response.getWriter();
        out.println("Beer Selection Advice<br />");
        String c = request.getParameter("color");
        out.println("Got beer color " + c);
      }
    }

当我编译它时，我收到以下错误：

  

找不到符号抛出IOExcpetion，ServletException

Answer 1

变化：

throws IOExcpetion

要：

throws IOException

Answer 2

错字：IOExcpetion应为IOException。
