h:message

The message tag renders a message for a specific component. You can customize the message generated by this component by applying different CSS styles to the message depending on its severity (eg. red for error, green for information) as well as the detail level of the message itself. You can also customize the standard error messages by overriding specific JSF properties in your message bundle.

Example

<h:inputText id="username" required="#{true}" value="#{userBean.user.username}" errorStyle="color:red" />
<h:message for="username" />

HTML Output

<input type="text" id="form:username" name="form:username" value="" />
<span style="color:red">"username": Value is required.</span>
