Olá a todos, tenho uma aplicação JSF e estou com o seguinte problema, toda vez que eu aperto o um botão de validação ocorre o seguinte erro

Unable to create managed bean

não estou conseguindo achar o erro

Meu faces-config

…um teste…

mas é que o Y ja tem os metodos gets e sets

public class Y{ //--------Atributos-------- private enviaSoap objSoap = new enviaSoap(); private SOAPMessage msoap = null; private String Resposta = "" ; private int teste; //--------Metodos GET e SET-------- public String getteste() { return this.teste; } public void setteste(String teste) { this.teste = teste; }

Estou falando desse atributo:

Y_ref
X_ref

X_ref

package web;

	//----Validacoes----//
	public void validacao()
	{
		Y_ref.setteste  (  X_ref.getteste() + X_ref.getteste2()   );
	}
}

deixei assim e continua o mesmo erro =/ ,

esse erro que esta dando

javax.servlet.ServletException: Unable to create managed bean W.  The following problems were found:
     - Property X for managed bean W does not exist.
     - Property Y for managed bean W does not exist.

jimmyhc 2 de set. de 2010

Criaste os getters e setters para:

public Y Y_ref;
public X X_ref;

???

victormenegusso 2 de set. de 2010

jimmyhc:

public Y Y_ref;
public X X_ref;

???

mas porque eu precisaria criar os get e sets deles se o tipo x e y já tem implementado ?

tipo quando configurei o faces ali pensei que que o X-ref seria uma referencia para o meu bean X ja criado… bom vou tentar fazer isso que você falou
^^

victormenegusso 2 de set. de 2010

mesmo colocando os gets and sets continua o mesmo erro =(

raf4ever:

continua o mesmo erro =/

victormenegusso 3 de set. de 2010

pior que eu ja nem sei oque fazer … ja tirei tudo da bean W deixando apenas o metodo de validacao sem nada dentro

package web;
public class W
{

	public void validacao()
	{
		
	}
}

e nada, fiz tb assim

package web;
public class W
{
	//----Atributos Referencia---//
	private Y Y;
	private X Y;
	//----Validacoes----//
	public void validacao()
	{
		Y.setteste  (  X.getteste() + X.getteste2()   );
	}
}

estás usando o Jboss Seam?

victormenegusso 3 de set. de 2010

então, eu primeiramente eu compilo e gero o pacote via maven, depois dou um deploy no jboss-soa-p.4.3.0, o estranho é que ele não acusa erro no deploy, e a pagina abre traquilamente, o erro da é quando eu clico no botão da pagina

victormenegusso 3 de set. de 2010
