Chris, This works for me:
<c:set var="GLOBAL_ERROR">
<%=org.apache.struts.action.ActionErrors.GLOBAL_ERROR %>
</c:set>
<html:messages id="errorMsgs"
message="true"
property="${GLOBAL_ERROR}"
header="errors.header"
footer="errors.footer">
<c:out value="${errorMsgs}" default="tag-error"
escapeXml="false"/>
</html:messages>I think by default your messages tag is not showing errors. That's what the 'property' attribute is for.
Also, although I've forgotten the details - I think that message="true" means that it will pick up the ActionMessages object from the request using a particular key, but you may have to set it to false or use another attribute - because you save your object back to the request differently from me. This is what I do in my action:
// Save messages back to request & session (in case of redirects) request.setAttribute(Globals.MESSAGE_KEY, messages);
Check out the taglib API.

OK,
Had the problem with using the html:messages with struts-el from the 1.1RC1 build (NullPointerException) - so I've just upgraded to 1.1 (thought I'd already done so).
Now - I get no exception - but I get no message either.
The servlet code:
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("message.login.failed"));
saveErrors(request, errors);
forward=mapping.findForward("loginfailed");
And in the jsp (note - this is using tiles - so the rest of the tags (<html> etc) are not in this file:
<%@ taglib uri="/struts-html-el.tld" prefix="html"%> <%@ taglib uri="/struts-logic-el.tld" prefix="logic"%> <%@ taglib uri="/c.tld" prefix="c"%>
<logic:messagesPresent> <html:messages id="error"> <p class="error"><c:out value="${error}"/></p> </html:messages> </logic:messagesPresent>
I am getting sent to the loginfailed mapping - but the message is not displayed - no <p class="error"> tags in the HTML at all.
It must be something stupid on my part - this looks to me to be the same as examples out on the net and in the docs.
Any hints welcome :-)
