<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> 

struts xml -

<?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> <constant name="struts.devmode" value="true" /> <package name="helloworld" extends="struts-default">    <action name="hello"          class="com.struts2.files.helloworldaction"          method="execute">         <result name="success">/helloworld.jsp</result>   </action> </package> </struts> 

any ideas why getting 404 when trying run app?

i guess, you've added wrong struts-core-1.3.10.jar classpath. belongs struts 1.x. need include latest struts2-core-2.x.x.jar struts 2 framework.

a typical struts 2 application has following jars under web-inf/lib directory.

commons-fileupload-1.2.1 commons-io-1.3.2 commons-logging-1.1 freemarker-2.3.13 junit-3.8.1 ognl-2.6.11 xwork-2.1.2 struts2-core-2.1.6 struts2-convention-plugin-2.1.6 (if using annotations)
