Struts Errors

[Venkat Babu]

How to retrieve the saved errors in the action class. I know the saveErrors() set the errors in the request object, but I don't know what's the key to retrieve.


java.util.HashMap map = (java.util.HashMap)request.getAttribute("???");


Thanks a lot.

First of all, the Object put in request scope by SaveErrors is not a HashMap, but an ActionMessages instance. Note that since ActionErrors is a subclass of ActionMessages, it could contain an instance of ActionErrors also.

The best way to retrieve and display it in your JSP is simply to use either the <html:errrors/> or <html:messages/> tag.

If you really want to retrieve it in a scriptlet, this is the code:

ActionMessages errors = (ActionMessages)request.getAttribute(Globals.ERROR_KEY);
