@Name @Stateful (default scope is conversation) @Name @Stateless (default scope is event, but the bean is truly stateless) @Name (default scope is event) anonymous wrote : If I put just @Name, it's a POJO, and you're saying it's request scoped? Yes. anonymous wrote : This still doesn't fully answer the question. Most things can be done with POJOs. For example most beans aren't message-driven. For many simple things there is no performance benefit to clustering beans. So, should we be using EJBs or POJOs? POJOs have a benefit of simplicity: no need to write an interface. You've summed up the arguements well, and so can now make an informed decision for which to use ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123371#...
