Getting Started with Struts Struts framework to build a simple zero-based learning Struts

Struts framework to build tools:
the Eclipse
Tomcat
students if not in eclipse plug-ins can be installed inside Toncat refer to this article
https://blog.csdn.net/weixin_44003632/article/details/86629997

First, we need to download jar package on the frame of the jar package I have uploaded to the CSDN, you can download
https://download.csdn.net/download/weixin_44003632/10938170
jar package is structured as follows

and then we need to build JAVA project, The project structure follows

the need to establish two packages, two JAVA classes, a struts-config.xml file and a web.xml file and three .jsp page.

After the establishment of complete, then the code can be more than
LoginAction.java

package com.lanp.webapp.action;

import java.util.ArrayList;

import javax.servlet.http.HttpServletRequest;
