<struts>

   <constant name="struts.enable.SlashesInActionNames" value="true"/>
   <constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>

   <package name="default" namespace="/" extends="struts-default">
      <action name="en/*" class="ir.mr.khatami.action.SensationalRequestAction" method="respond">

Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself.

Read http://struts.apache.org/docs/namespace-configuration.html and http://struts.apache.org/docs/wildcard-mappings.html#WildcardMappings-Parametersaftertheactionname. — Aleksandr M, Jun 21 '16 at 07:00
@AleksandrM Can you please update the link, both links shows `404 Page Not Found`? — Kavin Raju S, Feb 09 '22 at 02:35

Please review

https://struts.apache.org/docs/wildcard-mappings.html

The advanced title mention:

From 2.1.9+ regular expressions can be defined defined in the action name. To use this form of wild card, the following constants must be set:
<constant name="struts.enable.SlashesInActionNames" value="true"/>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.patternMatcher" value="regex" />

So your mapping must be

<action name="en/{type}" ...

You can read the type value in your action by simply adding String type with setter and getters.

PS: I can not test it right now but it seems to work

actually type don't needed to be stored some where. i just wanted to localize my site from any url after /en . – Mohammadreza Khatami Jun 23 '16 at 08:14
` ` I have this in my struts.xml, along with the xml tag for patternMatcher with the value of regex. But I get the error `There is no Action mapped for action name 2` when I access using the URL `http://localhost:8080/wildcard_sample/2/hello/3.json`. I am using `Struts 2.5.29`. @Alireza – Kavin Raju S Feb 09 '22 at 02:38
