Introduction To JavaEE

History Of javaEE

in 1995 introduced java.
but they can't develop Java alone.
because of that, in 1998 they established a community called JCP(Java Community Process).
people who are interested in Java development joined this community.
JCP Members always check what are the mistakes in Java.
if they noticed some mistakes they wrote documentation called JSR(Java Specification Request).
As a result, the JCP community came to Java Enterprise Edition(JavaEE).

Java has different kinds of editions.
- Standard Edition (JavaSE)
- Enterprises Edition (JavaEE)
- Micro Edition(JavaME)
At that time many people were trying to develop multiuser applications.
in that situation, java also tries to develop large-scale applications.
After that, James Gosline and his developers developed JavaEE in 1999.
That was a good solution for building web applications easily because JavaEE always tries to develop Large-scale applications/multi-user applications / complex logic applications.
JavaEE was developed by extending javaSE 8.
we can do anything that we do in JavaEE using JavaSE, but it was very difficult. we can manage our time & project complexity using JavaEE.
simply JavaEE is a set of specifications.
JavaEE was developed by Oracle to JEE8 only Now developed by Eclipse.
Eclipse changed JavaEE's name to JakarthaEE9.
After that many kinds of JavaEE specifications were released, and because of that many kinds of companies implemented these specifications.
- ex:- glassfish, JBoss, Wildfly, TomEE, TomCat
if we develop a JavaEE application we need these specifications.
