"vysvetlenie" deployment:
"For Enterprise Java Beans (EJB)
and some of the other APIs you must run through a setup (deployment is the J2EE term) process before you
can execute the code."
"Your next step will be to deploy this application to two different machines."
"You don't have to do anything special to deploy in JBoss if you are
building your application as a WAR instead of SSDD. I'm not saying it's
not easy with SSDD, I just haven't gotten SSDD to work in Tomcat the way
I've wanted it to work. "
"Java 2 Platform, Enterprise Edition (J2EE) je súbor noriem a postupov od spoločnosti Sun Microsystems, ktoré spoločne umožňujú vývoj, deploying a správu viacvrstvových aplikácií umiestnených na serveri."

a business logic:
"The methods that a remote interface presents to the world are commonly called business logic. Each method
should provide a solution to some problem that the system wishes to address"
"Táto vrstva sa zvyčajne nazýva „business logic“ a predstavuje abstrakciu funkčnosti. Už nie je potrebné starať sa o implementáciu databázy, pretože používateľské rozhranie komunikuje s abstraktnou reprezentáciou."

"If you're falling off a cliff,
you may as well try to fly.
You've got nothing to lose."
