Stateless Session Beans - when to have remove

[stephan.opitz]

i have an jsf application saving the reference to my ejbs in one javabean called datafactory

as i printed out for stateless beans in variable will be saved:

10:02:36,359 INFO [DataFactory] stateless: CategoriesLangImp

and for stateful:

10:02:36,359 INFO [DataFactory] stateful: SessionImpl:5c4o4yp-flv5bi-es4a7n25-1-es4a8mvn-7

so if i remove statful session bean by using ejb with reference 5c4o4yp-flv5bi-es4a7n25-1-es4a8mvn-7 is not more available.
but the stateless with which only handle ejb persistence should not be removed, but at all is it neccessary?
how long will the beans available on application server - is there any time limit?

thy so much

addition:
i remove with @remove annotation and it seems to me stateless will not be remove, but is it neccessary at all?

how long "live" the ejbs

No, it is not necessary to remove a stateless session bean.

One stateless session bean instance will be kept alive during the entire lifecyle of your deployment. Others might be instantiated and removed as necessary.
