How to create custom URL in Struts 2? Like www.twitter.com/goodyzain

If you want to use named patterns in wildcard mapping then you should configure following in the struts.xml:

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

now assume com.example.actions.ViewProfileAction bean has a property username, and method execute that returns a SUCCESS result. Then you can map the action in the root namespace "/" configured to your package.

<action name="{username}" class="com.example.actions.ViewProfileAction">
  <result>/WEB-INF/jsp/profile.jsp</result>
</action>

you can get the name in the JSP using OGNL

<s:property value="username"/>

Also note that you should deploy to the root context to have

your.domain.com/username mapped to your action.

Try this out. It may work. Use Freemarker USE $.

<action name="profiles/${username}" class="com.example.actions.ViewProfileAction">
    <result name="input">/WEB-INF/jsp/profile.jsp</result>
</action> 

It may work
