[Ginhu]

Galera,

Estou com o seguinte erro, qdo uso meu DAO na classe ManagerBean esse dao está null, creio que seja alguma configuração errada que eu fiz no spring, será que vcs poderiam me ajudar ??? Segue meus arquivos abrigado:

Por favor, preciso de ajuda, quem puder me add no gtalk:jatecnologia@gmail.com

Ginhu,

Se eu não me engano, no faces-config você tem que criar referência para os beans mapeados no applicationContext.xml.

E por falar nisso, cadê o applicationContext.xml? Você não listou.

Abraço.

[Ginhu]

Bland,

Então, meu applicationcontext.xml é esse :

       <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
          p:location="/WEB-INF/jdbc.properties" />
          
       <!-- JPA EntityManagerFactory -->
      <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
     p:dataSource-ref="dataSource">
           <property name="jpaVendorAdapter">
               <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
	p:databasePlatform="${jpa.databasePlatform}" p:showSql="${jpa.showSql}"/>
           </property>
       </bean>  
       <bean id="dataSource"   class="org.springframework.jdbc.datasource.DriverManagerDataSource"          
         p:driverClassName="${jdbc.driverClassName}"  p:url="${jdbc.url}"  p:username="${jdbc.username}"
          p:password="${jdbc.password}" />    

      <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
      <bean lass="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
  
      <bean id="transactionManager" 	class="org.springframework.orm.jpa.JpaTransactionManager">
        	<property name="entityManagerFactory" ref="entityManagerFactory" />
     </bean>
    
     <tx:annotation-driven />
     <context:annotation-config/>
     <context:component-scan base-package="com.diebold.medial.configurador.web.controller" />
      
</beans>       

Então eu tenho que colocar no applicationContext.xml meus managerbeans, tbm ???

É isso ???

[bland]

Ginhu,

Como te disse, acho que sim. Pelos exemplos que eu encontrei na internet você precisaria estar mapeando os beans do Spring no faces-config.xml através da #{bean_id_do_applicationContext}.

Faz uma tentativa e nos dê um retorno.

Abraço.

[Ginhu]

Galera,

Consegui resolver, o problema estava com o Spring que não estava fazendo a injeção de forma correta. Depois de muitas tentativas consegui resolver.

Obrigado pela força !!!
Abraços

[bland]

Ginhu,

Já que você conseguiu resolver, posta aqui pra nós como você fez isso.
Afinal de contas, outras pessoas podem estar passando pelo mesmo problema que você.
E então, como resolveu? Coloca aqui os fontes “corrigidos”.

Abraço.
