Struts 2 Tip #4 - Within a namespace, reuse names for common concepts.

In practice, most applications are composed of a small number of workflows that repeat within the application. When configuration elements in different namespaces serve the same role, use the same identifier for each element. If each namespace includes a "Menu" or a "Help" action, use those same names with each namespace.

<struts>

 <package name="receivables" namespace="/receivables">
  <action name="Menu" class="receivables.Menu" >
   <result>/receivables/Menu.jsp</result>
  </action>
  <!-- ... -->
 </package>
 <package name="payables" namespace="/payables">
  <action name="Menu" class="payables.Menu" >
   <result>/payables/Menu.jsp</result>
  </action>
  <!-- ... -->
 </package>

</struts>

Since the namespace feature avoids collisions between element names, we can increase cohesion within the application by using a consistent naming pattern.
