To configure the Struts2 action mapping we have to add an action node inside the configuration file struts.xml.

Here is an example for this:

<action name="*welcome" class="example.action.mapping.LinkAction" method="execute">

     <result name="success">/welcome.jsp</result>

     <result name="error">/error.jsp</result>

</action>
