Question

在尽我最大努力解决错误的过程中，我需要您的帮助来找到所遇到的错误的解决方案。

错误（在控制台中显示）是：

严重：适用于Servlet [servlet.RegisterServlet]中的Servlet.service（）路径为[/ Company_Mailer_System]的上下文抛出异常 java.io.FileNotFoundException：请求的资源[/Company_Mailer_System/header.html]在以下位置不可用 org.apache.catalina.servlets.DefaultServlet.serveResource（DefaultServlet.java:797）在 org.apache.catalina.servlets.DefaultServlet.doGet（DefaultServlet.java:454）在 org.apache.catalina.servlets.DefaultServlet.doPost（DefaultServlet.java:547）在javax.servlet.http.HttpServlet.service（HttpServlet.java:660）在 org.apache.catalina.servlets.DefaultServlet.service（DefaultServlet.java:434）在javax.servlet.http.HttpServlet.service（HttpServlet.java:741）处 org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:231）在 org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:166）在 org.apache.catalina.core.ApplicationDispatcher.invoke（ApplicationDispatcher.java:712）在 org.apache.catalina.core.ApplicationDispatcher.doInclude（ApplicationDispatcher.java:580）在 org.apache.catalina.core.ApplicationDispatcher.include（ApplicationDispatcher.java:516）在servlet.RegisterServlet.doPost（RegisterServlet.java:24）处 javax.servlet.http.HttpServlet.service（HttpServlet.java:660）在 javax.servlet.http.HttpServlet.service（HttpServlet.java:741）在 org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:231）在 org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:166）在 org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:53）在 org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:193）在 org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:166）在 org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:199）在 org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:96）在 org.apache.catalina.authenticator.AuthenticatorBase.invoke（AuthenticatorBase.java:494）在 org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:139）在 org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:92）在 org.apache.catalina.valves.AbstractAccessLogValve.invoke（AbstractAccessLogValve.java:651）在 org.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:87）在 org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:343）在 org.apache.coyote.http11.Http11Processor.service（Http11Processor.java:412）在 org.apache.coyote.AbstractProcessorLight.process（AbstractProcessorLight.java:66）在 org.apache.coyote.AbstractProtocol $ ConnectionHandler.process（AbstractProtocol.java:754）在 org.apache.tomcat.util.net.NioEndpoint $ SocketProcessor.doRun（NioEndpoint.java:1385）在 org.apache.tomcat.util.net.SocketProcessorBase.run（SocketProcessorBase.java:49）在java.util.concurrent.ThreadPoolExecutor.runWorker（未知来源）在java.util.concurrent.ThreadPoolExecutor $ Worker.run（未知来源）在 org.apache.tomcat.util.threads.TaskThread $ WrappingRunnable.run（TaskThread.java:61）在java.lang.Thread.run（未知来源）

我的代码如下：

package servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/RegisterServlet")

public class RegisterServlet extends HttpServlet 
{
 public void doPost(HttpServletRequest request, HttpServletResponse 
  response) throws ServletException, IOException
 {
     response.setContentType("text/html");
     PrintWriter out=response.getWriter();

    request.getRequestDispatcher("header.html").include(request, 
    response);      
    String name=request.getParameter("name");
    String password=request.getParameter("password");
    String email=request.getParameter("email");
    String gender=request.getParameter("gender");
    String dob=request.getParameter("dob");
    String addressLine=request.getParameter("addressLine");
    String city=request.getParameter("city");
    String state=request.getParameter("state");
    String country=request.getParameter("country");
    String contact=request.getParameter("contact");


    int status=dao.RegisterDao.save(name, email+"@cmailer.com", password, gender, dob, addressLine, city, state, country, contact);
    if(status>0)
    {
        out.print("<p>You are successfully registered!</p>");
        request.getRequestDispatcher("Login.html").include(request, response);
    }
    else
        out.print("<p>You are successfully not registered!</p>");
    request.getRequestDispatcher("footer.html").include(request, response);     
}}

header.html文件如下：

<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<style type="text/css">
.inputform{float:left;
width:400px;border:1px solid pink;border-radius:10px;padding:10px;
}
.inputform table tr td input,textarea,select{width:200px;}
#gender1,#gender2{width:10px;}
#submit{margin-left:100px;width:100px;} 
#reset{width:100px;}
.design{background-color:red;color:white;padding-left:100px;}
</style>
<body>
<!-- header -->
<h2>Company Mailer</h2>
<h3 style="background-color:red;color:red;">c</h3>
<!-- body -->
</body>
</html>

先谢谢您。
