espaços em branco com JSF

Tenho uma aplicação em jsf e gostaria de saber como faço para evitar q os usuários digitem no <h:inputText/> espaços em branco e retorne uma mensagem para o usuário.

para evitar q digite fiz o seguinte

mais ele ñ notifica nada para o usuário, como devo fazer???

Valeu a todos

Robson

Adiciona um <h:outputText> na página pra mostrar uma mensagem

E nesse método que vc criou vc setar um valor pra essa mensagem.

tem alguma forma para mim fazer isso e ñ perder o recurso de internacionalização???

Tem sim...

Cara eu fiz o seguinte

mais ñ rolou onde estou errando????

O que está dando errado?

Então cara é o seguinte ele ñ grava mais ñ dá mensagem nenhuma

então coloquei assim

e ta me dando esta mensagem de erro
