Sorry for missing that Matt.
The id = 'varName' is the object name which will hold each message in the
messages list as it iterates through.
All you should need is something along the following:
<logic:messagesPresent message="true">
<!-- are there any ActionMessages present? -->
<html:messages id="message" message="true">
<c:out value="${message}" /><br />
</html:messages>
</logic:messagesPresent>
This will examine the request for an ActionMessages object, then iterate
through it assiging each item to object "message". Then the c:out tag will
output the value of message and add a <br /> as a line break.

Mike
Thanks for response.
I had tried that but to no avail (I mentioned it near the end of my original
message)
I am not clear as to what 'id="messages"' which appears in the html:messages
tag is supposed to refer to. According to the docs:
"The name of a page scope JSP bean that will contain the current element of
the collection of messages on each iteration, if it is not null. [Required]"
http://jakarta.apache.org/struts/userGuide/struts-html.html#messages
Do I have to define this bean at any point other than in the tag?
Matt

Try setting the message="true" attribute of the <html:messages> tag. The
default is false which means that you are actually testing for ActionErrors
not ActionMessages.

Hello
I am hoping someone can help with an ActionMessages problem
I am setting ActionMessages in my action, but they are not appearing in the
page. The action code is:
if(showDetails.size() == 0 ) {
LOGGER.debug("no ShowDetails found");
ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage("errors.none.found", "showDetail"));
saveMessages(request,messages);
return mapping.findForward("none");
}
The JSP code is:
<logic:present name="<%=Action.MESSAGE_KEY%>">
<P>
messages found:
<html:messages id="messages"
name="<%=ActionMessages.GLOBAL_MESSAGE%>" bundle="JSP_MESSAGES"/>
</P>
</logic:present>
The log output confirms that the java snippet is called.
The 'messages found' string appears in the JSP, but no error message. I have
tried various configurations of params to the 'messages' tag, including
adding "message='true'".
I have the following in struts-config.xml
<message-resources key="JSP_MESSAGES" parameter="jsp-messages"
null="false"/>
I have a file in 'WEB-INF/classes' called 'jsp-messages.properties'
This contains the string: 'errors.none.found=No {0}(s) were found'
Hope someone can help - this one's got me stumped!
cheers
Matt
