Java EE Technology Stack

|
In this article, we will examine the components of Java EE technology stack and historically look at the new comer components and version changes in the components along with the Java EE versions. I will use this article as the umbrella for Java EE stack and update for every new features added to Java EE.

About Java Enterprise Edition

Under the container architecture named Java Enterprise Edition;
  - business logic (projects to EJB)
  - contents or presentations (projects to Servlet, JSP, JSF)
are developed as software components and then run in a managed execution environment named containers.

 In terms of Java EE, there are two types of containers;
  • Web container
    • In web container, the components are generated in the form of Servlet, JSP and JSF, called web components.
    • Tomcat is a Java EE web container in which web components can be executed.
  • Application container
    • In the application container, the components are generated in the form of EJBs.
    • Weblogic, Websphere, Tom EE are some of JEE compliant application servers.

What containers do ?

Containers provide essential services to components and execute the life cycle of components.
Samples for the provided services by containers:
  • Security
  • Transaction management
  • Life cycle management
  • Request dispatching
Below is the diagram for the web and ejb containers and the services provided for each in Java EE 5:

Java 14 New Features

|
Java SE 14 was released in March 2020. The full list of new features in JDK 14 can be found here: https://openjdk.org/projects/jdk/14/   In this tutorial, we will look over some of these new features and examine some of them. 1. JEP 305: Pattern Matching for instanceof (Preview) With this JEP, instanceof now allows casting of the checked object to a variable. Before Java 14: if (obj instanceof String) { String s = (String) obj; // use s } With Java 14: if (obj instanceof String s) { // can use s here } else { // can't use s here } 2. JEP 345: NUMA-Aware Memory Allocation for G1 This JEP i mproves G1 performance on large machines by implementing NUMA-aware( non-uniform memory access ) memory allocation. Use the  +XX:+UseNUMA option to enable it. 3. JEP 358: Helpful NullPointerExceptions This JEP  improves the usability of  NullPointerException  generated by the JVM by describing precisely which variable was  null . Let's look over the following code which throw

Pretenders, Contenders and Liars

|
Life is a way to the uncertainity. This is an exact fact. In this uncertain journey, we meet kinds of people of having different behaviours, and generally label them according to their behaviours. In this writing, i will try to write my understanding of three of these labels; pretenders, contenders and liars. Pretenders A pretender is a kind of people who pretends :) It does not do what it seems to do. It does what it does not seem to do. We frequently meet pretenders in our daily life. And if we catch a person pretending, then we feel that is not sincere. Okay, then here is a question sincerely to ask yourself; do you ever find yourself pretending ? Contenders A contender is a person who has a goal to reach and do not hesitate to fight for that goal. So a contender is sincere ? Absolutely yes, you may be completely opposite to a contender, but if you know that it's a contender, then you know that it's sincere in its behaviours. And sure it is, if you trus

Java 12 New Features

|
Java SE 12 was released in March 2019. The full list of new features in JDK 12 can be found here: https://openjdk.org/projects/jdk/12/   In this tutorial, we will look at some of these new features and examine some of them. 1. JEP 189:  Shenandoah: A Low-Pause-Time Garbage Collector (Experimental) Shenandoah is a new garbage collection (GC) algorithm which reduces GC pause times,  independent of heap size. This GC algorithm is experimental so in order to use it with Java 12, you have to enable it : -XX:+UnlockExperimentalVMOptions -XX:+UseShenandoahGC 2. JEP 325:  Switch Expressions (Preview) This JEP extends the switch statement to be used as either a statement or an expression. Meaning that we can now return a value from a switch expression. Before Java 12, we can return a value by assigning it to a variable: String getColor(int num) { String result = ""; switch (number) { case 1, 2, 3: result = "red, green or blue"; break;
