Struts 2.x unable to load configuration.-Action

Problem Analysis: this problem is generally caused by the incorrect configuration of a configuration file in struts, for example:

1. testaction in class is not loaded successfully:

    <constant name="struts.i18n.reload" value="true" />     <!-- <include file="struts/struts-test.xml"/> -->     <package name="system" extends="struts-default">        <action name="totalfilter" class="TestAction">              <result name="success" >success.jsp</result>                   </action>      </package>

2. mistakenly write name as type, for example:

<! -- Correct syntax --> <result name = "error">/error. jsp </result> <! -- Incorrect syntax --> <result type = "error">/error. jsp </result>
