Para utilizar o jboss Seam o meu managedBean tem sempre que ser um ejb? To acustumado a utilizar jsf onde tenho um managed bean e nele faco lookup para acessar os ejbs, tem como continuar trabalhando desta maneira ?
Achei meio estranho os exemplos que vi as paginas chamando metodos nos componetes seam que sao ejb’s, isso é correto?

Eu sei q tem como fazer sem EJB, mas eu não lembro agora pois faz tempo q não uso o Seam.
Mas lá no curso da Caelum eles me ensinaram a não usar EJB para os MB

sera que alguem teria um exemplo de como montar esta estrutura, aki criei um ManagedBean da registrei ele no faces, e ainda utilizei a anotacao name do seam nele, tbm criei um metodo que retorna uma lista e anotei como @Factory porem ele nao carrega a lista na tabela na view, alguem tem um exemplo ai pra ajudar:

Bom dia :!:

um componente Seam não precisa ser um EJB e também não deve ser registrado no faces-config.
Só a anotação @Name é suficiente (ou pode definir ele através do components.xml).

Sobre os exemplos, já olhou os que o próprio Seam disponibiliza? contei 34 exemplos no Seam 2.2.2 que tenho aqui.
Um ótimo livro é o ‘Seam in Action’ do Dan Allen.

Posta o Seam Component e a o página para ajudarmos.

Meu Mbean:

@Name("acaoMbean")
@Scope(ScopeType.PAGE)
public class AcaoMbean {

	@DataModel
	private List<Acao> acoes;

	
	private AcaoDaoEjbLocal acaoDao;

	public AcaoMbean() {
		try {
			acaoDao = ServiceLocator.getInstance().lookup("SeamProject-ear",
					AcaoDaoEjbLocal.class);
		} catch (EjbNotFoundException e) {
			e.printStackTrace();
		}	
	}

	@DataModelSelection
	@Out(required = false)
	public Acao selectedAcao;

	
	
	@Factory(autoCreate=true,value="acoes") 
	public void list() {
		acoes = getAcaoDao().listAll();
	}

A pagina xhtml ta assim:

<ui:define name="body">		
		<h:form id="AcaoEjbForm">
			<h:commandButton actionListener="#{acaoMbean.list}" value="Listar">
			</h:commandButton>

			<rich:panel>
				<f:facet name="header">acaoEjb</f:facet>

				<rich:dataTable id="tabela" value="#{acaoMbean.acoes}" var="item"
					align="center" rows="10" width="70%">
					<rich:column>
						<f:facet name="header">
							<h:panelGroup>
								<h:outputText value="Acao" />
							</h:panelGroup>
						</f:facet>
						<h:outputText value="#{item.acao}" />
					</rich:column>


					<rich:column>
						<f:facet name="header">
							<h:panelGroup>
								<h:outputText value="Detalhe" />
							</h:panelGroup>
						</f:facet>
						<h:outputText value="#{item.detalhe}" />
					</rich:column>


					<rich:column>
						<f:facet name="header">
							<h:panelGroup>
								<h:outputText value="Item (Lazy)" />
							</h:panelGroup>
						</f:facet>
						<h:outputText value="#{item.item.numeroItem}" />
					</rich:column>
				</rich:dataTable>

			</rich:panel>



		</h:form>

	</ui:define>

Tenho somente uma tabela e um botao listar nesta pagina, coloquei breakPoints e o construtor do AcaoMbean nunca é chamado, nao tenho declarado nada no faces , ele nao deveria criar o bean automaticamente? o @factory tbm nao deveria ser chamado e ja listar os dados automaticamente na tabela?
Obrigado pela ajuda.

qdo clico no botao listar ele da esta exception:
Caused by: javax.el.PropertyNotFoundException: /acaoEjb.xhtml @13,71 actionListener="#{acaoMbean.list}": Target Unreachable, identifier ‘acaoMbean’ resolved to null

Para mim, seu Seam Component está ok. Vc está utilizando o segundo estilo de Factory que eu não estou acostumado, mas também está correto.

...
Vc não precisa chamar o método da factory assim.

O bind da Factory está para 'acoes'. Na hora que vc chamar #{acoes}, o Seam irá primeiro procurar se já não existe o valor no escopo (perceba que ocorre um cache).
Se não existir (estiver null), a Factory irá chamar o seu método que popula o 'List acoes' e te retornará a lista acoes.

lgGodoy:
...
				<rich:dataTable id="tabela" value="#{acaoMbean.acoes}" var="item"
					align="center" rows="10" width="70%">
...
Aqui vc está chamando o método #{acaoMbean.acoes} que tem retorno void. Tente somente #{acoes} para usar a Factory e ter a lista como retorno.

Quando vc inicia a aplicação, deve aparecer no log os componentes iniciados, inclusive o seu. Deve aparecer algo assim: 10:04:57,249 INFO [Component] Component: acaoMbean, scope: PAGE, type: JAVA_BEAN, class: pacote.AcaoMbean
lgGodoy:
o @factory tbm nao deveria ser chamado e ja listar os dados automaticamente na tabela?
Correto, vc nem precisará do botão listar pois a factory fará isso automaticamente. Só precisa ajustar a chamada.

Obrigado pela ajuda.
Por nada :!: :)

Fiz as adequacoes que vc ensinou acima, e notei que no log nao aparece meu componente acaoMBean veja:

Por que sera que ele nao esta subindo no log?

opa agora funcionou, tirei as anotacoes e coloquei direto no components.xml

<component auto-create="true" class="br.com.mbean.AcaoMbean"
  name="acaoMbean" scope="page"/>

exite alguma configuracao especifica para usar annotations no seam? gerei meu projeto com o jbossTools .

Estranho ele não estar iniciando seu componente.
Também utilizo a versão 2.2.2.Final e não lembro de ter tido esse tipo de problema.

O Seam percorre as suas classes procurando as que possuem @Name…

:idea: Estou vendo no meu projeto aqui, tenta criar um arquivo ‘seam.properties’ vazio no diretório raiz de suas classes.

lgGodoy

Coloquei o arquivo properties no msm pacote do componente acaoMbean e msm assim nao funcionou, engracado que neste mesmo pacote tenho o componente que o jbossTools gerou automaticamente e este aparece no log:

10:47:48,743 INFO  [Component] Component: authenticator, scope: EVENT, type: JAVA_BEAN, class: br.com.seam.ejb.Authenticator

ja implementei Serializable , achei que podia ter algo a ver, agora ja nao sei mais o que pode ser os dois componentes estao com as anotacoes @Name dei uma vasculhada nos arquivos de config pra ver se tinha alguma referencia do componente Authenticator, e so encontrei isso no components,xml:

<security:identity authenticate-method="#{authenticator.authenticate}" remember-me="true"/>
 <event type="org.jboss.seam.security.notLoggedIn">
  <action execute="#{redirect.captureCurrentView}"/>
 </event>

Mas ele so esta declarado com @Name no bean msm, pq um funciona e outro nao?

rock

acho que não é no pacote, pelo menos aqui não tenho um em cada pacote, e sim no diretório raiz dos fontes…

tipo:
src/seam.properties
src/br/com/projeto/MeuSeamComponent.java

:arrow: fiz um teste removendo o seam.properties e meus componentes nao foram iniciados.

Deve ser isso.

è nao teve jeito msm, verifiquei que é um problema da versao do jboss que eu utilizo, ele nao permite injecao de depencias no
bean, que no meu caso nao é um ejb, sendo assim vou manter os beans declarados no components.xml.
Agora estou com outra duvida nao consigo injetar uma entityManager com a anotacao @In do Seam,
estou tentando assim:

//no components.xmls tenho isso:
<persistence:managed-persistence-context auto-create="true"
  name="entityManager"
  persistence-unit-jndi-name="java:/SeamProjectEntityManagerFactory"  />

//no persistence.xml tenho isso:
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/SeamProjectEntityManagerFactory"/> 

//E no EJb tenho isso:
@In(value = "entityManager", create = true)
	public EntityManager getEntityManager() {		
		return entityManager;
	}

Ja tentei injetar no set , direto no atributo, porem nuca injeta, o que pode ser isso, quero que o seam controle a entityManager para evitar problemas com lazy exception?

L
lgGodoy

Qdo utilizo :

Component.getInstance("entityManager");

Ele encontra a entityManager, pq será que pela anotacao @in ele nao consegue injetar este maldito?? Alguem tem uma ideia do que pode ser isso?

qual versão do JBoss vc utiliza? já testei o @Name com JBoss 4.2, 5.0, 5.1, 6 e funcionou em todos…
tentasse com o seam.properties na raiz do diretório dos fontes ao invés de ser dentro do pacote como eu comentei no post anterior?

tenta assim:

@In private EntityManager entityManager;

ou

@In("#entityManager") private EntityManager entityManager;

L
lgGodoy

Utilizo a 4.2.1, nesta versao nao consegui de maneira alguma anotar os MBeans, porem consegui injetar a entityManager, no meu ejb nao tinha colocada a anotacao @Name do seam , depois que coloquei consegui injetar a EntityManager com @In, no meu Mbean consigo ate injetar os ejbs com @In , so nao funciona anotar o Mbean com @Name.
