For this tutorial, you’ll learn about giving feedback to your users with validation messages, and how easy JSF makes this process.
Liferay Faces Bridge automatically applies the JSR 286 standard CSS class names
portlet-msg-warn to the
h:messages tags. This means you can use the
h:messages tags and have access to the standard validation messages.
You’re now equipped to give feedback to users with validation messages in your JSF portlet.
