Adding an error to the ActionError in struts

[Archana Annamaneni]

In my application I am trying to add an error message to an ActionError.
That message is in a String varibale , how do i add that,if it is an hardcoded message it works fine.

here is my code

String errormessage = (String)detailids.get(1);
errors.add(ActionErrors.GLOBAL_ERROR,new ActionError("100",errormessage));
saveErrors(request,errors);

Thanks
