我是一名学生,正在学习使用jsp和servlet构建Web应用程序。我的Web应用程序项目自一个月以来一直运行良好,但今天突然表现异常。当我提交我的jsp页面时,它无法找到我的servlet。我已经使用了servlet注解来映射请求。
以下是我的jsp代码:
<form name=registration_form action="<%=application.getContextPath() %>/Registration" method="post">
First Name:</td><td><input type="text" name="firstName" required/></td></tr>
</form>
以下是我的Servlet代码:
package servlets;
@WebServlet("/Registration")
public class Registration extends HttpServlet {
private static final long serialVersionUID = 1L;
public Registration() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String firstName=request.getParameter("firstName");
System.out.println(firstName);
}
}
以下是我的web.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Login</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
以下是我的项目层次结构:
以下是错误信息:

以下是我的控制台日志:
