I got back to application development using Java after spending the last 4 years developing applications using .Net and C++ and things have really changed!!! I have spent the last one month trying to catch up on all the new stuff in the Java world. Updating myself with the latest changes to the syntax only took one day though and I was surprised to see that in the latest incarnation Java 5 and .Net are like twins. If you don’t believe me then read this.
So after updating myself with the platform changes I started going through the technology stack, it’s been a month and I think I have only scratched the surface of whats out there and I’ve been only looking at enterprise application development technologies, it actually took me a week to review all the web application development options! So far here’s what I’ve looked at, as in, read through the reference manuals, installed and played around a bit, Hibernate, JPA, JDBC, Spring, Struts, EJB, Velocity, Tapestry, WebWorks, Cocoon, Log4j, JBoss, Tomcat, JNDI, JMS, NetBeans, Eclipse, Jetty, Glassfish.
Today while I was trying to read the official docs for Java EE, I spent half an hour on the Sun site trying to decide what I wanted to download, did I want Java SE 6 or Java EE 5 
Well after finally finding what I wanted, I went for a coffee break and for some reason the dialogue between Neo and the Architect from “Matrix Reloaded” kept popping up in my mind. I think the connection I was making is that the Java eco-system has become extremely complex, not unlike the stage C++ had reached before the advent of Java, at that time Java was “Neo”.
So who’s the new “Neo”? I really can’t predict, but it’ll be simple to use, have less configuration, it just works defaults, easy to get started, eventually have good performance and most importantly have a passionate user community, that will keep improving on it and ultimately cause it to become the next Java 
. Looking at todays options, I think “Ruby” seems to meet this criteria the most. You never know 5 years down the line we could all be thinking about how it took weeks to setup a simple application using the Java platform and how going through all those xml files and annotations gave you a headache.
I’ve included the entire dialogue between Neo and the Architect below, substitute the Matrix for Java and Neo for Ruby and njoy!
The Architect - Hello, Neo.
Neo - Who are you?
The Architect - I am the Architect. I created the matrix. I’ve been waiting for you. You have many questions, and although the process has altered your consciousness, you remain irrevocably human. Ergo, some of my answers you will understand, and some of them you will not. Concordantly, while your first question may be the most pertinent, you may or may not realize it is also irrelevant.
Neo - Why am I here?
The Architect - Your life is the sum of a remainder of an unbalanced equation inherent to the programming of the matrix. You are the eventuality of an anomaly, which despite my sincerest efforts I have been unable to eliminate from what is otherwise a harmony of mathematical precision. While it remains a burden to sedulously avoid it, it is not unexpected, and thus not beyond a measure of control. Which has led you, inexorably, here.
Neo - You haven’t answered my question.
The Architect - Quite right. Interesting. That was quicker than the others.
*The responses of the other Ones appear on the monitors: “Others? What others? How many? Answer me!”*
The Architect - The matrix is older than you know. I prefer counting from the emergence of one integral anomaly to the emergence of the next, in which case this is the sixth version.
*Again, the responses of the other Ones appear on the monitors: “Five versions? Three? I’ve been lied too. This is bullshit.”*
Neo: There are only two possible explanations: either no one told me, or no one knows.
The Architect - Precisely. As you are undoubtedly gathering, the anomaly’s systemic, creating fluctuations in even the most simplistic equations.
*Once again, the responses of the other Ones appear on the monitors: “You can’t control me! F*ck you! I’m going to kill you! You can’t make me do anything!*
Neo - Choice. The problem is choice.
*The scene cuts to Trinity fighting an agent, and then back to the Architect’s room*
The Architect - The first matrix I designed was quite naturally perfect, it was a work of art, flawless, sublime. A triumph equaled only by its monumental failure. The inevitability of its doom is as apparent to me now as a consequence of the imperfection inherent in every human being, thus I redesigned it based on your history to more accurately reflect the varying grotesqueries of your nature. However, I was again frustrated by failure. I have since come to understand that the answer eluded me because it required a lesser mind, or perhaps a mind less bound by the parameters of perfection. Thus, the answer was stumbled upon by another, an intuitive program, initially created to investigate certain aspects of the human psyche. If I am the father of the matrix, she would undoubtedly be its mother.
Neo - The Oracle.
The Architect - Please. As I was saying, she stumbled upon a solution whereby nearly 99.9% of all test subjects accepted the program, as long as they were given a choice, even if they were only aware of the choice at a near unconscious level. While this answer functioned, it was obviously fundamentally flawed, thus creating the otherwise contradictory systemic anomaly, that if left unchecked might threaten the system itself. Ergo, those that refused the program, while a minority, if unchecked, would constitute an escalating probability of disaster.
Neo - This is about Zion.
The Architect - You are here because Zion is about to be destroyed. Its every living inhabitant terminated, its entire existence eradicated.
Neo - Bullshit.
*The responses of the other Ones appear on the monitors: “Bullshit!”*
The Architect - Denial is the most predictable of all human responses. But, rest assured, this will be the sixth time we have destroyed it, and we have become exceedingly efficient at it.
*Scene cuts to Trinity fighting an agent, and then back to the Architects room.*
The Architect - The function of the One is now to return to the source, allowing a temporary dissemination of the code you carry, reinserting the prime program. After which you will be required to select from the matrix 23 individuals, 16 female, 7 male, to rebuild Zion. Failure to comply with this process will result in a cataclysmic system crash killing everyone connected to the matrix, which coupled with the extermination of Zion will ultimately result in the extinction of the entire human race.
Neo - You won’t let it happen, you can’t. You need human beings to survive.
The Architect - There are levels of survival we are prepared to accept. However, the relevant issue is whether or not you are ready to accept the responsibility for the death of every human being in this world.
*The Architect presses a button on a pen that he is holding, and images of people from all over the matrix appear on the monitors*
The Architect - It is interesting reading your reactions. Your five predecessors were by design based on a similar predication, a contingent affirmation that was meant to create a profound attachment to the rest of your species, facilitating the function of the one. While the others experienced this in a very general way, your experience is far more specific. Vis-a-vis, love.
*Images of Trinity fighting the agent from Neo’s dream appear on the monitors*
Neo - Trinity.
The Architect - Apropos, she entered the matrix to save your life at the cost of her own.
Neo - No!
The Architect - Which brings us at last to the moment of truth, wherein the fundamental flaw is ultimately expressed, and the anomaly revealed as both beginning, and end. There are two doors. The door to your right leads to the source, and the salvation of Zion. The door to the left leads back to the matrix, to her, and to the end of your species. As you adequately put, the problem is choice. But we already know what you’re going to do, don’t we? Already I can see the chain reaction, the chemical precursors that signal the onset of emotion, designed specifically to overwhelm logic, and reason. An emotion that is already blinding you from the simple, and obvious truth: she is going to die, and there is nothing that you can do to stop it.
*Neo walks to the door on his left*
The Architect - Humph. Hope, it is the quintessential human delusion, simultaneously the source of your greatest strength, and your greatest weakness.
Neo - If I were you, I would hope that we don’t meet again.
The Architect - We won’t.
