configuracao de ambiente e primeiros passos jsf

olá Gustavo

Esse tipo de erro acontece quando há mais de uma versão do JSF no classpath. Que jars você tem na sua aplicação?

2.2

2.2. ate tentei criar um novo projeto e nada . mesmo erro...

mas no geral so uma versao no classpath

Ok, pela exception você ta usando o tomcat né? Poderia postar seu web.xml?

sim vamos la
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>livraria-jsf</display-name>
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>
</web-app>`

`

Nada de mais no seu web.xml. Pedi pra ver pois se alguma configurações estivesse duplicada também poderia causar erros.

Consegue colocar o seu projeto no dropbox e me mandar o link por email ( mario.amaral@caelum.com.br )? Não consigo imaginar o que mais poderia ser, precisaria olhar com calma pra achar o problema.

ok ta mandei ve se eh isso?

Olhando seu print, me parece que está faltando jars no seu projeto. Vejo que você tem o JSF APi, mas não tem o JSF impl. O jar que é pedido no vídeo (http://s3.amazonaws.com/caelum-online-public/JSF/javax.faces-2.1.14.jar) é uma compilação desses dois, jsf-api e jsf-impl. Tente baixar desse link aqui e troque o jar do seu projeto.

kra segui a video aula no capitulo 2. eh realmente eu instalei esse e ai deu erro ai entrei no site e baixei o 2.2 outra coisa. o video ja ta desatualizado a pag para baixar o jar ta desatualizada

e ai como faço?

segui a video aula...

baixe daqui: https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/2.2.7/javax.faces-2.2.7.jar.

Você pode acahr as ultimas versões sempre nesse site: https://javaserverfaces.java.net/2.2/download.html

Teste ai e me diga se deu certo.

fui isso mesmo que eu fiz. mas tudo bem faço de novo. lembrando cheguei a instala o 2.1 q vc flw antes ta?

baixei pelo link que vc flw. copiei pra pasta lib restartei o apache e deu esse erro

Agora o JSF subiu, mas vc tem um erro no seu livro.xhtml:

Error Parsing /livro.xhtml: Error Traced[line: 5] O prefixo "h" do elemento "h:body" não está vinculado.

Poste o seu livro.xhtml.

baixei o arquivo do link https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/2.2.7/javax.faces-2.2.7.jar. copiei pra pasta lib

</html>

tem um erro na linha 3 do seu arquivo. troque:

<html xmlns="http://www.w3.org/1999/xhtml">

por

<html xmlns="http://www.w3.org/1999/xhtml"

após isso deve funcionar.

vai fica a mesma coisa , num vai nao?

Não, são diferentes.

Se você reparar, eu removi o último caractere, um >, que estava fechando a tag html antes da hora, por isso seu código não funciona.

O erro principal é esse:

Target Unreachable, identifier 'livroBean' resolved to null

Verifique se a classe LivroBean está anotada com @ManagedBean. Veja também se importou a annotation do pacote certo, o correto é javax.faces.bean.

Mario esta.

Não sei que pode ser então, precisaria importar o projeto aqui e testar. Consegue me enviar o projeto por email?

mandei mario

Olá Gustavo.

O projeto subiu normalmente aqui, quando cliquei no botão de gravar deu erro.

o erro foi o seguinte:

Caused by: javax.el.MethodNotFoundException: /livro.xhtml @20,72 action="#{livroBean.livro.gravar}": Method not found: br.com.caelum.livraria.bean.Livro@709f4d93.gravar()
    at com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:109)
    at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:87)

Na linha 20 do seu livro.xhtml existe a seguinte linha:

<h:commandButton value ="Gravar" action="#{livroBean.livro.gravar}"/>

Nesta linha você está dizendo que existe um método gravar em Livro. Na verdade, o método é na classe LivroBean. O código correto é:

<h:commandButton value ="Gravar" action="#{livroBean.gravar}"/>

Acho que é isso.

Abraços
