JAVA_HOME\SEVERLET下有JAVA\SERVLET和JAVAX\SERVLET而且HTTPSERVLET.CLASS都有了!

  1.   

    Hi.java代码:
    import java.io.*;
    import java.servlet.*;
    import javax.servlet.*;
    public class Hi extends HttpServlet
    {
    public  void doGet(HttpServletRequest req,HttpServletResponse res) throws IOException,ServerException
    {
    res.setContentType("text/html");
    PrintWriter out=res.getWriter();
    out.println("<html>");
    out.println("<body>");
    out.println("<head>");
    out.println("<title>Hello,you</title>");
    out.println("</head>");
    out.println("<hl>Hello,you</hl>");
    out.println("</body>");
    out.println("</html>");
    }
    }
      

  2.   

    例如:import java.io.*;
    是不是有个BufferedReader.class?那么
    那个BufferedReader.class类放在什么目录下?
