If the message is not related to anything special you use the label ActionErrors.GLOBAL_ERROR. A sensible solution could be to put our messages in some kind of Java Collection, maybe a LinkedList: Listing 1: Using a List to hold messages List messages = new LinkedList();messages.add("Data So you can validate your properties within this method. Many of the Struts tags don't do what you'd expect when specifying name. this content

The reason is that the tag forced you to place HTML in the message resource file, which is not nice.

There is one issue however in doing this. First we enter "tryChecked1" in the tryexception.jsp page. It's also necessary since we want to move Java code away from error.jsp. I am not clear what's your concern. –Clark Bao Aug 21 '11 at 13:35 Hi Clark, thanks for time.

I don't show them here because they're simple extensions of the base Exception class.

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request){ ActionErrors errors = super.validate(mapping, request); return errors; } In JSP : for the I put entries for the validation.xml and But the new SpringBindingAction bean seems to do something differently. I have a bunch of questions regarding RC1. You give a "label" when you add an ActionMessage.

The first version of it simply lists all objects in request and session scope, takes the stored exception and prints it: Listing 10:An error jsp page<%@ page language="java" %><%@ page import="java.util.*" http://ibookmate.blogspot.com/2009/06/struts-actionmessages-and-actionerrors.html The most interesting attribute, besides the ones we've already seen, is the handler attribute.

They're almost identical to the Message classes, and most of what I'll explain below for the Message classes works equally well for the Error classes.

However, Struts has a more powerful mechanism for storing and handling messages based upon the ActionMessage and ActionMessages classes.If you're already a Struts user you may know the ActionErrors and ActionError errors.minlength={0} can not be less than {1} characters. the error.jsp page, where you can inform the user of the error, and how he or she can proceed. this contact form errors.long={0} must be a long.

You may use the field Globals.EXCEPTION_KEY to retrieve it from the request object, so we make a small modification to error.jsp to handle our own and now also Struts' exception: . Why there are no approximation algorithms for SAT and other decision problems? To get a realistic snapshot of the error it's very valuable if each method in this chain can add data for the logging mechanism.

In Doctor Strange what was the title of the book Stan Lee was reading in his cameo?

errors.maxlength={0} can not be greater than {1} characters. BTW, I did not have the exception you mentioned until now (I think the code which is compiled against 1.2 like the ActionMessage constructor mentioned above wasn't executed until now). If not, we simply return to the jsp-page.

Hope it helps! If you want to display an error associated with a form property use the attribute property of the html:messages tag. errors.float={0} must be a float. Earlier we saw that messages from the ActionMessages object are displayed like this:
