Could anyone give an validator example?

Question

<af:inputText label="name" validator="#{localTest.validateName}" id="message"/>
<af:message for="message"/>
<af:commandButton action="home" text="submit"/>
public void validateName(FacesContext facesContext, UIComponent uIComponent,
Object object) {
// Add event code here...
facesContext.addMessage("message", new FacesMessage(FacesMessage.SEVERITY_ERROR,"str1","str2"));
what i want is if validation failed, action for commandButton submit should not be executed, but it does.
so how to use validator properly? how did managed bean know whether validation succeed or failed, cause no boolean return from validation method.

Hi Kevin,
You can use following code:
public void validateName(FacesContext facesContext, UIComponent uIComponent, Object object) {
    // Add event code here...
    FacesMessage mess = new FacesMessage();
    mess.setSummary("Validation summary message");
    mess.setDetail("Validation detail message");
    mess.setSeverity(FacesMessage.SEVERITY_ERROR);
    throw new ValidatorException(mess);
