Intercept JSF-validations

Question

I am starting to get to know JSF and I have been able to add some standard validators that show up in messages that I have defined, but they only validate when I click the button to submit the form where the components that need to be validated are in. I would like those components to be validated already on the moment that I click outside them (for example with onblur), but I don't know which method I have to call in the onblur-property to execute the validator of that element? The code I have at this moment is:

<h:form>
  <h:outputText value="#{msgs.name}"/><br/>
  <h:inputText id="name" value="#{user.name}" label="#{msgs.name}" required="true" requiredMessage="#{msgs.name_required}"/>
 <h:message for="name" styleClass="error_single_message"/>
  <br/><br/>

  <h:outputText value="#{msgs.password}"/><br/>
  <h:inputText id="password" value="#{user.password}" label="#{msgs.password}" required="true" requiredMessage="#{msgs.password_required}"/>
  <h:message for="password" styleClass="error_single_message"/>
  <br/><br/>

  <div class="error_overview_messages">Overview errors
  <h:messages showDetail="#{true}" showSummary="#{false}"/>
  </div><br/>

  <h:commandButton value="Log_on" action="logged_in"/>
</h:form>

JSF validations happens server side, so you will essentially need to have a submit triggered to have server side code activated.

If you are not interested in that, you need to activate some specific Java script.

If you are using JSF2, you can accomplish what you are looking for by adding Richfaces to your build and using Richfaces client side validation:

Richfaces Client Side Validation

It is a great new feature in their v4 release that compiles standard jsf validators and JSR-303 bean validation to javascript that can be executed client side. You can trigger the validations on any standard javascript event (blur, click, keyup).
