Descoberta Automática de Beans utilizando JSF e Spring

Front-end
#21

Pessoal, fiz várias tentativas utilizando as dicas de vocês mas ainda não consegui resolver o problema. O bean é retornado nulo. Alguém pode me explicar passo a passo como devo fazer ???
Alguém me dá mais uma força aí ?

#22

Vou mostrar como eu uso. Também é JSF 1.2 e Spring:

web.xml:

 <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
  </listener>

faces-config.xml:

	<application>
	
	   <resource-bundle>
			<base-name>message</base-name>
			<var>msg</var>
		</resource-bundle>
	
		<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
		<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
	</application>

applicationContext.xml:

<bean
		class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />
	<bean
		class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

	
	<bean id="contextApplicationContextProvider" class="context.ApplicationContextProvider" />
	<tx:annotation-driven />

	<context:component-scan base-package="*" />

Exemplo de uso:

Bean injetado:

@Component
public class ProjetoDaoImp extends GenericDaoImp<Projeto,Long>
implements ProjetoDao{
@Component
public class ProjetoController {

	@Resource
	ProjetoDao dao;

raf4ever, o projeto não roda...dá aquele erro: HTTP Status 503...

    &lt;tx:annotation-driven /&gt;

    &lt;context:component-scan base-package="controle" /&gt;

&lt;/beans&gt;

meu controlador(bean):

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package controle;

import org.springframework.stereotype.Component;

@Component
public class Controle {

    private String usuario;
    private String senha;

    public Boolean login() {
        if (getUsuario().equals("admin") && getSenha().equals("admin")) {
            return true;
        }
        return false;
    }

    public String getSenha() {
        if (senha == null) {
            senha = "";
        }
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }

    public String getUsuario() {
        if (usuario == null) {
            usuario = "";
        }
        return usuario;
    }

    public void setUsuario(String usuario) {
        this.usuario = usuario;
    }
}

fiz este método login que é chamado pelo commandButton bem simples só para caráter de teste mesmo…

Fiz também a validação do arquivo applicationContext.xml após colocar as configurações que você me passou e ele me retornou o seguinte erro:

The prefix "context" for element "context:component-scan" is not bound. [34]
#24

Ainda precisa de algumas modificações:

Pode retirar esses dois trechos:

 &lt;context-param&gt;  
        &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt;  
        &lt;param-value&gt;/WEB-INF/applicationContext.xml&lt;/param-value&gt;  
    &lt;/context-param&gt;  

  &lt;servlet&gt;  
        &lt;servlet-name&gt;dispatcher&lt;/servlet-name&gt;  
        &lt;servlet-class&gt;org.springframework.web.servlet.DispatcherServlet&lt;/servlet-class&gt;  
        &lt;load-on-startup&gt;2&lt;/load-on-startup&gt;  
    &lt;/servlet&gt;

E adapta o cabeçalho do teu applicationContext.xml de acordo com esse:

&lt;beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"

Cara, parece que está quase dando certo…
agora faltou componente dispatcher, olha a saída da IDE:

Deploying application in domain failed; Error loading deployment descriptors for module [PROJETO] -- There is no web component by the name of dispatcher here. /home/NetBeansProjects/PROJETO/nbproject/build-impl.xml:713: O módulo não foi implementado. FALHA NA CONSTRUÇÃO (tempo total: 0 segundos)

Vixe,esse erro eu nunca vi.Tá usando qual servidor de aplicacao?

#27

Glassfish 2.1

#28

Glassfish 2.1[/quote]

É mandatório usar um AS full-stack? Tinha como testar num Tomcat da vida?
