Struts: ActionMessage vs. Action Error

[Jessica Doe]

I read in one book that ActionError is being deprecated in favor of ActionMessage. Another book mentions nothing of this. Is it so? Should I convert my ActionErrors to ActionMessages?

Can you put an Action Error in ActionMessages? If so, how do you pull only errors or messages out?

Thanks,

Jess

Hi,

It is true that ActionError is being deprecated in favour of ActionMessage, unfortunately the validate method of ActionForm still returns the ActionError object, so to work around it what you can do is instead of putting the ActionErrors objects into ActionErrors, put the ActionMessage objects.

 
ActionErrors actionErrors = new ActionErrors();
     actionErrors.add("CompanyName",new ActionMessage 
                   (ErrorConstants.ERROR_REQUIRED,"Company Name"));
    actionErrors.add("Phone No", new ActionMessage
                    (ErrorConstants.ERROR_REQUIRED,"Phone No"));

 

and to access this errors in the jsp page use this code

  <html:messages id="msg" message="false" >
<li><bean:write name="msg"/></li>
</html:messages>
