     <h:panelGrid columns="2">
       <h:outputLabel value="EmailId" />
       <p:inputText value="#{userController.registerUser.emailId}" required="true" label="EmailId"/>
   
       <h:outputLabel value="Password" />
       <p:password value="#{userController.registerUser.password}" required="true" label="Password"/>
   
       <p:captcha label="Captcha" theme="red"/>
       <h:outputLabel value="" />
     
       <p:commandButton value="Register" ajax="false" actionListener="#{userController.doRegister}" />
   
     </h:panelGrid&gt...
