I searched for the materials online, Because I imported jar files.Package yes. If one is missing, the following packages should be imported::

Add commons-logging-1.0.4.jarAnd do not report these errors. However, the following error is reported.:

The content of the Struts. xml configuration file is as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Struts> <! -- Add the default struts2 configuration file --> <include file = "struts-default.xml"/> <! -- Inherits the default struts2 configuration file, similar to Java inheritance --> <package name = "default" extends = "struts-Default"> <! -- Here, "hello" is the URL name of "Hello. Action" --> <action name = "hello" class = "Controller. helloaction"> <! -- Success points to configuration --> <result name = "success"> success.html </result> </Action> </package> </struts>

 Because the doctypt definition is missing in the Struts. xml file, add:

<!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd">

The correct configuration file is as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <! Doctype struts public "-// Apache Software Foundation // DTD struts configuration 2.0 // en" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <! -- Add the default struts2 configuration file --> <include file = "struts-default.xml"/> <! -- Inherits the default struts2 configuration file, similar to Java inheritance --> <package name = "default" extends = "struts-Default"> <! -- Here, "hello" is the URL name of "Hello. Action" --> <action name = "hello" class = "Controller. helloaction"> <! -- Success points to configuration --> <result name = "success"> success.html </result> </Action> </package> </struts>
