I want to add an icon for an input text element, in a JavaEE project:
<h:panelGroup styleClass="md-inputfield">
    <p:inputText id="name"
                 value="#{createCustomerView.customer.name}" required="true"
                 label="Nome" requiredMessage="inserisci il nome">
        <f:validateLength minimum="2" />
    </p:inputText>
    <p:outputLabel for="name" value="Nome" />
    <p:message for="name" display="icon" />
</h:panelGroup>
How Can add an icon, like a person icon?
