I tried the example from the HelpTagsErrorsAndMessages.html in my jsp
near the top of the body.
<logic:messagesPresent>
<h3><font color="red"></font>Messages:</h3>
<ul>
<html:messages id="msg">
<li><bean:write name="msg" /></li>
</html:messages>
</ul>
</logic:messagesPresent>
The action that forwards to that jsp has:
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_MESSAGE, new
ActionMessage("error.detail",retStatus));
this.saveErrors(request, errors);
where retStatus is a string.
And in my ApplicationResources.properties I have
error.detail={0}
But when I run it I get
org.apache.jasper.JasperException: Cannot find bean msg in any scope
...
----- Root Cause -----
javax.servlet.ServletException: Cannot find bean msg in any scope

regarding the <html:errors> tag. You can use either <html:errors> or
<html:messages> with ActionMessage, its just down to personal
preference.
I've added a page comparing <html:errors> and <html:messages> here:
http://www.niallp.pwp.blueyonder.co.uk/HelpTagsErrorsAndMessages.html
You can use either
As for the validate method in your action form - then whether you use
<html:errors> or <html:messages> the you can do something like the
following...
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (<some conditon here>) {
errors.add("myProperty", new ActionMessage("myProperty.error"));
}
return errors;
}
