Struts2 Version 2.3.15 HelloWorld Setting

1. Problem:
There are some different after struts2 2.1.3, e.g. the library and the strtus.xml, web.xml setting file


2. Solution:
A. Downlaod form struts-2.3.15.1-lib.zip

B. Use the following Basic library, and copy to WebContent/WEB-INF/lib:
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
commons-fileupload-1.3.jar
commons-io-2.0.1.jar
commons-lang-2.4.jar
commons-lang3-3.1.jar
commons-logging-1.1.3.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.15.1.jar
xwork-core-2.3.15.1.jar

C. Writing the web.xml, there we use the StrutsPrepareAndExecuteFilter

<?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_2_5.xsd"
    version="2.5">
   
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

D. Writing the struts.xml in Project_dir/Java Resource/src and write your action class
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<constant name="struts.devMode" value="true" />
    <package name="default" extends="struts-default"> 
        <action name="hello" class="ibms.struts2.HelloWorldAction" method="execute">
            <result name="success">/HelloWorld.jsp</result>
        </action>
       
    </package>
</struts>
