Question

我正在尝试运行一个从jsp页面获取请求的servlet。部署项目没有问题但是当我从jsp页面提交请求时，我的服务器没有导航到servlet文件。我收到的 HTTP状态404 - / reg 是我的web.xml文件。请帮帮我

   `<?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" 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>Registration</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>

  </welcome-file-list>

  <servlet>
  <servlet-name>RegistrationServlet</servlet-name>
  <servlet-class>org.com.servlet.RegistrationServlet</servlet-class>
  </servlet>

  <servlet-mapping>
  <servlet-name>RegistrationServlet</servlet-name>
  <url-pattern>/reg</url-pattern>

  </servlet-mapping>


</web-app>`

这是我的JSP文件。

Answer 1

在表单标签中使用action =“RegistrationServlet”。表单操作标记中的servlet调用是错误的。您的操作是“/ reg”，但是当它转到web.xml时，未找到servlet名称reg，因此显示404未找到错误。

HTTP状态404 - / reg
