Even hashmap lookups get heavy when the map is loaded with a piles and piles of
objects.
On the DP's, don't kind yourself.... techniques come and go, the core DP's
(these are not limited to Java, but are universal) are pretty much forever.
But the problem is that I have an basic application:
Facade--> AS --> AS --> DAO -->Entity
|__>DAO-->Entity
Why in heavens name, would I want to add a service locator between my As and
DAO? Can you spell U S E L E S S O V E R H E A D? Not to mention the
additional possible bottleneck of the locator.
For you basic homegrown application this might seem fine, but I talking about
an application with a steady rate of over 10k+ active users.... A little addon
like Session DAO's and Service Locators will add a substantial amount of
required process power.
Is there anyone who can tell me how to obtain an Entity Manager in a DAO,
without turning the DAO into a Session?
