Use global result handlers for common results

Often, actions will share a number of common results. Rather than configure redundant result elements for each action, share common results through a global result handlers.

<struts>
<global-results>
  <result name="error">
    /common/Error.jsp
  </result>
  <result name="invalid.token">
    /common/Error.jsp
  
  <result name="login" type="redirectAction">
    Login_input
  </result>
</global-results>
  <!-- ... -->
</struts>

Using global result handlers ensures that common results will be handled consistently, while reducing redundant code. Global results increase coupling, but any action that needs to handle a result differently can provide a local handler.
