Entity beans are considered to exist if the database record(s) that populate the
bean exist. Therefore the number of entity beans is limited only by the number
of records a database can handle - i.e. many millions. As to how many of those
that can be instantiated at the same time, this is limited by the amount of
memory in JVM(s) allocated to storing the entities. It's impossible to give a
number but I'd say that for certain types of application (especially where the
proportion of reads to writes is very high) it would make sense to allocate many
megabytes of memory.

I doubt any company has implemented a "complete and complex enterprise business"
using only EJB but there are some pretty big EJB applications out there.
