Tricky one. In *general* there are no "best ways" or "have to"'s. You might
want to read the primay key generation thread in this forum, and the threads
on theserverside.com with regard to this topic.
I am currently planning on adding an id generator to the "jbosstest" module,
both to act as a ground for discussion, and for people to use in their own
applications. I will most likely opt for one stateless session bean and one
CMP EntityBean to solve this. We will see how it turns out.

Generally no, becuase there may be several instances of a stateless session
bean. However, since we have a special stateless session bean pool for
singletons (i.e. one which only contains one single instance) this is
possible to do by using that pool. Create a new container configuration to
use with your bean, and be sure to make it use this special pool.
