Would it be correct to say that bijection (@In, @Out) is strictly for passing components between the jsf and ejb/pojo layer? Can bijection be used to pass components from sfsb to sfsb? Or should I rely on passing the component as a parameter to a method call to the second ejb (sfsb) from the first? I know this is very broad but right now I am under the impression that bijection is just shoving my components out into some magical place with @In and calling them back out with @Out. This "magical place" being reachable from both the jsf and ejb layers. I am just looking for some futher understanding on what is going on and the intended purpose(s) of bijection.
