Hi i have a situation where I need to design an error page (intelligent one)

So the requirement says

If I populate the ActionMessages class with the error message and use SaveMessages() in one of the action, the error page should be smart enough to identify that there is an ActionMessage (by using html:messages id=msg message=true or something like that) and print the error in the JSP error page.

If there is no error message (populated in the ActionMessages) then display a generic error message.

How to do this ???

It is sorta covered in the JavaRanch Style Guide.
