[jboss-user] [JBoss Seam] - Sending (Seam) mail from a scheduled service

[frehan]

Hi I am tryin to send seam mails from a service and I can't get it to work.

My service checks my db every 1o minutes for updates and if it finds any a mail schould be sent.

>From my service I look up a stateless session bean using

InitialContext ctx = new InitialContext();
mailer =  (se.test.Mailer) ctx.lookup("Camitz/Mailer"); 

I now that I can't inject in a service so I have to do a lookup

My session been is annotated like  this:

@Stateless
@Name("mailerAction")
@Interceptors(SeamInterceptor.class)
@LocalBinding (jndiBinding="Camitz/Mailer")
@Scope(ScopeType.CONVERSATION)


The method for sending the mails :
public void sendAlarm(String to, String subject, String message){

  AlarmMailBean mailBean = new AlarmMailBean(to,subject,message,link);
  Contexts.getConversationContext().set("alarmMail", mailBean);
     try {
	 Renderer.instance().render("/mail/mailTemplate.xhtml");
      } 
      catch (Exception e) {
    	  e.printStackTrace();
      }
 } 

When the renderer is called I strangely get 2 different kinds off exceptions.

1.

Exception 1. I dont understand but exception 2 is because I am not in a seam context.
How can I create a seam context or workaround this problem? 
I have tried to use org.jboss.seam.contexts.Lifecycle.beginCall(); in my method but it did not help.
Or is it impossible to use seam mail from a service?

Best Regards Fredrik
