You need to configure in web.ini

find the relevant posting here:
U can use either Global Exception Handling/ Exception handling for Action. Depends on the requirement u can use global or action specific here i can give... action specific exception..

you need to handle an exception in a specific way for a certain action you can use the exception-mapping node within the action node.

   <action name="actionspecificexception" class="org.apache.struts.register.action.Register" method="throwSecurityException">
     <exception-mapping exception="org.apache.struts.register.exceptions.SecurityBreachException"
          result="login" />
      <result name="login">/login.jsp</result>

The above action node from the example application's struts.xml file specifies that if method throwSecurityException throws an uncaught exception of type SecurityBreachException the Struts 2 framework should return a result of login. The login result will cause the user's browser to be redirected to login.jsp.

You can see that an action-specific exception mapping will take precedence if the same exception is also mapped globally

Here above i have given an example.. Base on ur exception type you can give the results page...
