Envers and current user in Seam 3

[marx3]

Hello

It's probably simple but I didn't find good answer. In documentation there is an example with Seam 2 using Component.getComponent to access username. Hovewer in Seam 3 I need to use another method. I can use in listener

BeanManagerLocator locator = new BeanManagerLocator(); BeanManager beanManager = locator.getBeanManager();

(I can probably extends BeanManagerAware interface too, but above method works)

But I don't know how to lookup current session bean? Will BeanManager give me only my session bean, and not beans of other logged in users?

Maybe I should use RevisionListener interface on some type of bean? But what scope such a bean should use?

I will answer myself:

BeanManagerLocator locator = new BeanManagerLocator();

if (locator.isBeanManagerAvailable()) {

            BeanManager beanManager = locator.getBeanManager();

            @SuppressWarnings("serial")
            Set> beans = beanManager.getBeans(User.class, new AnnotationLiteral() {});
            if (beans != null && beans.size() > 0) {
                @SuppressWarnings("unchecked")
                Bean bean = (Bean) beans.iterator().next();
                CreationalContext ctx = beanManager.createCreationalContext(bean);
                currentUser = (User) beanManager.getReference(bean, User.class, ctx);
                LOG.info(currentUser.toString());
            }
        }

It's the same code, only abstracted...

I know, just an util (and a couple of others) that may come in handy
