Olá Pessoal?!
Estou iniciando em meus estudos web com JSF. E não consigo resolver este problema.
Segue abaixo o meu código fonte
Classe UsuarioBean.java
package financeiro.web;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
public class UsuarioBean {
private String nome;
private String email;
private String senha;
private String confirmaSenha;
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getSenha() {
return senha;
}
public void setSenha(String senha) {
this.senha = senha;
}
public String getConfirmaSenha() {
return confirmaSenha;
}
public void setConfirmaSenha(String confirmaSenha) {
this.confirmaSenha = confirmaSenha;
}
public String novo() {
return "usuario";
}
public String salvar() {
FacesContext context = FacesContext.getCurrentInstance();
if(!this.senha.equalsIgnoreCase(this.confirmaSenha)) {
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Senha confirmada incorretamente", ""));
return "usuario";
}
// salva o usuário
return "sucesso";
}
}
