Ok. But only one DS per deployed bean?

Yes, you're wrong :-) They are always available in bean methods, even create
methods.

You don't get the environment entries from the entity context. Are you
referring to getEnvironment()? That has been deprecated. Use the
java:/comp/env JNDI namespace instead (i.e. new
InitialContext().lookup("java:comp/env/jdbc/BeanDS")).

Sure you can. You are not hardcoding the name of the real pool, you are
hardcoding the name of your reference to it. BIIIG difference. You can have
"java:comp/env/jdbc/BeanDS" point to *either* "java:/HypersonicDS" or
"java:/OracleDS" or.. etc. So the name can indeed be hardcoded. That's the
whole point.
I suggest that you look again into how environment entries and resource
references work in EJB 1.1.
