Send mail and LazyInitializationException

wagner.gsantos Nov 5, 2009 3:50 AM

Hello!
I'm trying send e-mail with seam-mail, but I'm getting LIE when do this. Somebody can help me? See the code:

public void enviaEmailEAtualiza(Prazo prazo) {
          
          final Map<String, Object> objetosContextuais = new HashMap<String, Object>();
          objetosContextuais.put("prazo", prazo);
          objetosContextuais.put("processo", prazo.getProcesso());

          //I do this to try eliminate the problem
          objetosContextuais.put("advogadoGestor", prazo.getProcesso().getAdvogadoGestor());
          objetosContextuais.put("advogadoEmpresa", prazo.getProcesso().getAdvogadoEmpresa());

          asynchronousMailProcessor.envia(10000, "/mail/PrazoVencido.xhtml", objetosContextuais);
          }
     }

In template:

<m:from name="Não responda"
          address="sender@novosrumosdesenvolvimento.com.br" />
     <m:to name="#{advogadoGestor.nome}">#{advogadoGestor.email}</m:to>
     <m:cc name="#{advogadoEmpresa.nome}">#{advogadoEmpresa.email}</m:cc> ...

And, then, I'm get LIE:

ERROR: [05/11/2009 - 00:47:28] could not initialize proxy - no Session
org.hibernate.LazyInitializationException: could not initialize proxy - no Session
     at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:86)
     at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:140)

Thanks for any help and sorry for my bad English.

You need to make sure all related entities and fields are loaded before you pass your entity to your asynchronous method.
Looks like you are getting an error on Usario.getEmail(), is the email field lazily loaded? If som, make sure you access it (or better yet, join fetch it) before you kick off the async method. Try something in the lines of:

objetosContextuais.put("advogadoGestorEmail", prazo.getProcesso().getAdvogadoGestor().getEmail);

and then use it in your template:

<m:to name="#{advogadoGestor.nome}">#{advogadoGestorEmail}</m:to>
