You can pass this pointers around of EJBs and expect transactions to work. This is because EJBs have a container that sits in front of bean instances so that it can handle things like transaction bounders. You should instead do: | @Resource SessionContext ctx; | | | public void processar(...) | { | TempoRealRN thisPtr = ctx.getBusinessInterface(TempoRealFN.class); | CorFrente = new ThreadCorFrente(controladorComum, this, log, dto, nomeThreadFrente, grupoFrente); | tCorFrente.addObserver(this); | tCorFrente.start(); | } | | You'll also have to have TempoRealFN extend the Observer interface probably.
