Jsf - validar login campos requeridos

Front-end
#1

Olá
Bom dia!

Preciso validar esse meu login da seguinte maneira :
Nao posso fazer login sem preencher os inputs
ou seja teria que apresentar uma mensagem de requerido nos dois input caso o usuario queira
submeter a pagina sem preencher os campos.

Como faria isso?

Estou enviando o jsp e o bean.

Grato

Vamos la então saca essa

<h:inputText id=“user” value="#{userLogin.usuario}" required=“true” immediate=“true” requiredMessage=“Campo requerido” maxlength=“10” />

blz ???

claro que para aparecer a mensagem vc precisa colocar tbm isso

<h:message for=“user” />

tudo junto fica assim

<h:inputText id=“user” value="#{userLogin.usuario}" required=“true” immediate=“true” requiredMessage=“Campo requerido” maxlength=“10” />
<h:message for=“user” />

Abraço e boa programação.

#3

Fiz assim:
<h:inputText id=“inputUsu” size=“15” maxlength=“15” binding="#{formLogin.inputUsu}" required=“true” requiredMessage=“o campo Usuário deve ser preenchido”></h:inputText><h:message for=“inputUsu”/></h:message>

Estou tendo esse erro ao executar o jsp:

o que poderia ser ?

#5

Tirei a acentuação e Quando adiciono a tag de validação ele me da o seguinte erro:

Error Parsing /pages/login.jsp: Error Traced[line: 18] The element type “h:panelGrid” must be terminated by the matching end-tag “</h:panelGrid>”.

Se tirar as tag as propiedades de validacao ele funciona ok

saberia me dizer o que esta rolando ?

Segue o jsp com o um inpuText.

Grato
