not displaying messages
i have this in my actionForm:
ActionMessages messages = new ActionMessages();
messages.add("message",
new ActionMessage("message.login.confirmation"));
saveMessage(request,messages);
in my jsp i have
<html:messages />
it doesn't work, i have tried the following options which don't work
either
<html:messages message="true"/>
<html:messages id="msg" property="messages" message="true">
<c:out value="${msg}"/>

I'm stumped. Are you using something like Sun ONE where you can trace
through your code and examine variables? I would just suggest following
along through everything, from the Action to the JSP, seeing what happens to
the message resources. It looks like it should work to me... :(

This sounds silly, but I can't tell you how many times I forgotten to
include the taglib on the page and wondered why things wouldn't
print:).., Have you checked that you have the bean tag lib defined
on your page?
<%@ taglib uri="/WEB-INF/struts-bean-el.tld" prefix="bean"%>
(Your location maybe different)

What do you mean? Aren't we talking at the HTTP protocol level?
When you say "another class" do you mean another "WEB" object?
I mean, it should be possible to forward/redirect also to a PHP page,
shouldn't it?
The forward/redirect semantics is tied to the Java Framework that we are
using or is it more general?
And what are the effect of enabling the redirect property of a
struts action?
A presto,
Fabio

When you forward, you pass control to another class within your current
application root context.
When you redirect, you can pass in or out of the context.

Forward <=> RequestDispatcher.forward()
(http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/RequestDispatcher.html)
Redirect <=> HttpServletResponse.sendRedirect()
(http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/http/HttpServletResponse.html)
Big difference is that redirect sends an HTTP Response back the browser
with a redirect header, generating a new request from the browser. This
makes it in general slower and less efficient. Also, the Request
object (and anything that you have shoved into it) is not preserved. On
the other hand, redirect gives you control over the destination URL.
Search the archives for full discussion.

What is the exact difference between forwarding and redirecting? What are
their implications?
I searched the Servlet and JSP specs but I haven't found nothing about
that.

Are you redirecting or forwarding to your JSP from that Action?

Just to see if this gets you anywhere, do
messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage
("message.login.confirmation"));
saveMessages(request, response);
then use
<html:messages id="message" message="true">
<bean:write name="message"/><br>
</html:messages>
