A little confuse on stateful context scope types

[gus888]

Anybody can explain the distinguish among the stateful context scope types listed below. If I don't use long-running conversation, their functionalities are same? Thank you very much in advance.

@Name("myAction")
@Stateful
@Scope(ScopeType.EVENT)
public class MyActionBean implements MyAction {
...
}

@Name("myAction")
@Stateful
public class MyActionBean implements MyAction {
...
}

@Name("myAction")
@Stateful
@Scope(ScopeType.CONVERSATION)
public class MyActionBean implements MyAction {
...
}

Well, the default scope of a stateful bean is "conversation" and with non-long-running conversation the conversation lives for (just slightly longer?) the same time as the request.

So I would say they are the same in this case.
