Open session in view - session closed?

Boa tarde pessoal!

Após dicas de nossos amigos do fórum, eu mudei minha configuração do hibernate, para “open session in view”…
Ficou perfeito meu código, e os problemas que eu vinha tendo com LAZY, acabou…
A estrutura que usei do open session in view, é igual o do manual do jboss…
O problema agora que estou, é com o JSF f:ajax, ou p:ajax… Quando eu tenho um selectonemenu, e um p:ajax nele, ele consegue executar o método, mas dá como session closed.

Ficou assim o dao:

public class CidadeDao implements Serializable { Session currentSession; public CidadeDao() { currentSession = HibernateUtil.getSessionFactory().getCurrentSession(); } public List<Cidade> listarTodos(Estado estado) { return currentSession.createCriteria(Cidade.class) .add(Restrictions.eq("est_id", estado)) .addOrder(Order.asc("cid_nome")) .list(); }
O selectonemenu:

<p:selectOneMenu id="estado" value="#{novoClienteBean.comboBean.estado}" converter="converterEstado" > <f:selectItem itemLabel="Selecione" /> <f:selectItems value="#{novoClienteBean.comboBean.estados}" var="e" itemValue="#{e}" itemLabel="#{e.est_nome}" /> <p:ajax listener="#{novoClienteBean.comboBean.listaCidades}" immediate="true" event="change" update=":novoCliente:cidade" /> </p:selectOneMenu>
Método que o selectonemenu chama:

public void listaCidades() { cidades = cidDao.listarTodos(estado); }

E o erro:

WARNING: /vendas/novoCliente.xhtml @115,169 listener="#{novoClienteBean.comboBean.listaCidades}": org.hibernate.SessionException: Session is closed! javax.el.ELException: /vendas/novoCliente.xhtml @115,169 listener="#{novoClienteBean.comboBean.listaCidades}": org.hibernate.SessionException: Session is closed! at com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:111) at org.primefaces.component.behavior.ajax.AjaxBehaviorListenerImpl.processAjaxBehavior(AjaxBehaviorListenerImpl.java:42) at javax.faces.event.AjaxBehaviorEvent.processListener(AjaxBehaviorEvent.java:113) at javax.faces.component.behavior.BehaviorBase.broadcast(BehaviorBase.java:106) at javax.faces.component.UIComponentBase.broadcast(UIComponentBase.java:760) at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:794) at javax.faces.component.UIViewRoot.processDecodes(UIViewRoot.java:935) at com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:78) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:593) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1550) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:343) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:217) at br.com.zanzini.filter.HibernateSessionRequestFilter.doFilter(HibernateSessionRequestFilter.java:17) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:256) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:217) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:279) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:655) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:595) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:161) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:331) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:231) at com.sun.enterprise.v3.services.impl.ContainerMapper$AdapterCallable.call(ContainerMapper.java:317) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:195) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:860) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:757) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:1056) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:229) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:137) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:104) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:90) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:79) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:54) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:59) at com.sun.grizzly.ContextTask.run(ContextTask.java:71) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:532) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:513) at java.lang.Thread.run(Thread.java:722) Caused by: org.hibernate.SessionException: Session is closed! at org.hibernate.impl.AbstractSessionImpl.errorIfClosed(AbstractSessionImpl.java:49) at org.hibernate.impl.SessionImpl.createCriteria(SessionImpl.java:1508) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.hibernate.context.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:301) at $Proxy145.createCriteria(Unknown Source) at br.com.zanzini.dao.CidadeDao.listarTodos(CidadeDao.java:53) at br.com.zanzini.bean.ComboBean.listaCidades(ComboBean.java:38) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at com.sun.el.parser.AstValue.invoke(AstValue.java:254) at com.sun.el.MethodExpressionImpl.invoke(MethodExpressionImpl.java:302) at com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:105) ... 39 more

Daí eu pensei "ele pega a sessão no construtor, e se eu colocar um “cidDao = new CidadeDao();” dentro do metodo listarCidades? Eu fiz isso e daí a mensagem é:

Alguém já passou por isso e conseguiu resolver?

Acho que seu problema está aqui: Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: br.com.zanzini.entity.Estado

Basta colocar esse cara attached na transação que vai dar tudo certo.

Sou iniciante em java web, como eu faria esse anexo na transação?

Primeiramente, parábens pelo blog que na verdade é um livro muito "cheio".

Muito obrigado! Consegui resolver, não sei se foi da melhor forma possível, mas eu consegui entender um pouco qual era o problema...

Como é open session in view, o que eu fiz foi colocar o cascade persistent no meu atributo Estado que fica na entidade Cidade, e depois pra buscar todas as cidades, eu coloquei:
[code] estDao = new EstadoDao();
cidDao = new CidadeDao();
cidades = cidDao.listarTodos(estDao.getEstadoById(estado.getEst_id()));[/code

Estou com o mesmo problema. Porém acho que só ocorre quando eu mudo o meu ManagedBeam para @ViewScoped, pois usando @RequestScope tive problemas com dataTable do primefaces e vi alguém aconselhando a serializar o bean e coloca-lo em ViewScoped

a minha página carrega normalmente mais quando utilizo filtro filterBy na coluna da dataTable ai recebo a exception

Possuo o seu livro de JPA eficaz e adquiri recentemente o JSF eficaz

Há alguma relação entre o open session in view com outros escopos?

Alguém???

rodrigo.uchoa 25 de mai. de 2014

Realmente não sei qual é o seu problema só olhando os trechos que você colocou. Uma coisa que me chamou atenção entretanto é o fato de você ter implementado o seu próprio “filter”, quando o Spring já disponibiliza um (e voce ta usando Spring). Não seria melhor usar o dele? É menos provável de possuir erros.
