error tag

Hello,

     I am handling my errors and constructing an errors object thus:

ActionErrors errors = new ActionErrors();
                errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("Initialisation error - userID not found"));
                saveErrors(request, errors);
                return mapping.findForward(FORWARD_error);

how from the JSP do I iterate over the errors object and retrieve the messages please? I have tried <html:errors/> but nothing was rendered to the screen?

thanks

Jerald,

The first parameter to ActionMessages.add() is a string interpreted to be
either ActionMessages.GLOBAL_MESSAGE or a name of one of your form fields.
If you had a field on your form that was named (i.e. property=...)
"username", then if you wished to add a message pertaining to this field,
then you would write: messages.add("username", errorMsg).  You're not
getting any messages displayed probably because you don't have a form field
with property="init_message."

Cheers,
Noel

Hi Noel,

   Thanks for that. Since that post, I have opted for constructing an
ActionMessages object and populating it with ActionMessage (s). This being
because I hear ActionError/s are deprecated as of Struts 1.2.

    I have set up the Application.properties file under
WEB-INF/classes/resources containing:

initialisation.error=Initialisation error - invalid UserID

I catch the exception thus:

ActionMessages messages = new ActionMessages();
                ActionMessage errorMsg = new
ActionMessage("initialisation.error");
                messages.add("init_message", errorMsg);
                saveMessages(request, messages);

and forward off to the error page, but nothing is rendered.

Any idea here? Perhaps something to do with the init_message string I am
passing? What does that represent?


appreciated

G.



Hi Jerald,

The single-string ActionError class constructor that you are invoking
interprets the parameter passed to it as a key of a message string defined
in your Application.properties file (this file is usually placed under the
classes/resources directory).

Hi

with<bean:message key="card.title"/> you can read messages from your properties file

btw, If I get nothing back in JSP it's because I forget the taglibs...
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>

it just occurrred to me, perhaps it may be due to the JSP:

<html:errors />

as ActionMessages are not soley used for error handling? If this is the case, what error tag will extract the error labels defined in my Application.properties?

thanks again
