# How Big Is Actually The EJB 3.1 Container In Glassfish v3? - Because EJBs are Hevyweight, It Has to be Huge...

Glassfish v3 is modular, so you can easily install and uninstall modules on the fly. Therefore it is very easy to measure the "disc-size" of a particular technology. The whole installation package (for GF v3 prelude b24) takes ...324 KB (three jars: connector, timer service, and the actual implementation). It is small enough to be executed on SunSPOTs or cellular phones.... So how would you call a complete framework with 324 KB "Heavyweight"? :-)I plan to demonstrate this, as well as some Java EE 6 features at JUG HH. Warning: some design patterns will probably die during the session :-). So see you in Hamburg!
