should help you out If you're used to writing HTML, switch to the simple theme.
In struts.xml is probably the best place:
code :

seems to work fine This is because you are incorrectly using a "chain" result. Don't use it unless you know what are you doing. To fix error you should change the configuration like this
code :
<action name="add" class="net.ajeet.os.view.OSAction" method="add">
  <result type="redirectAction">index</result>
  <result name="input">/index.jsp</result>
</action>

<action name="index" class="net.ajeet.os.view.OSAction">
  <result>/index.jsp</result>
</action>

Hope this helps There's a method in ActionSupport class getActionErrors() that you can use along with the code
code :
getActionErrors

Collection<String> getActionErrors()

Get the `Collection` of Action-level error messages for this action. 
Returns:
    Collection of String error messages
if (getActionErrors().contains("myError")) {
  //your code here
}
