Java EE tutorials is a series of short Java EE tutorial chapters with sample examples and config/compile/run how-tos. The series is followed by a comprehensive Java EE project development tutorials (from software engineering prescriptive) for a Hotel Reservation Management System. The development tutorials start with requirements gathering (with stakeholder conversations), and ending with the deployment instructions and guidelines. The development tutorials are attached with the final project executables, source files, icons, and all other legal resources to make the final system run. Copyrighted for author’s own usages.

Being Professional

Being professional is an informal session, presented as a Computers and Information Faculty, Mansoura Univ., graduate, in IT Zoom 3, on 15/12/2009, at 11:00 AM. I liked this session sooooo much, because it was long years ago since I presented my last session to my colleagues.

JVM Implementation with Python – Proof of Concept

Abdalla Mahmoud — Tue, 08 Dec 2009 15:12:43 +0000

One of the major steps I always believed that it would improve my skills in Java programming and training is learning the Java bytecode. Understanding the low level details of the Java Virtual Machine draws a bigger and deeper picture in your mind about the environment, performance tuning, security issues, reverse engineering, and much more. It also complements your Java programming language concepts, Object-Oriented concepts, and the exact definition of the various Java constructs. And one other step, learning python. Python is the language of the coming era, I believe. So what? I will write a JVM in Python!

It was a funny idea for learning both, so I decided to begin. I started reading the JVM specification, learning Python, and writing some code. 10 days later, I came out with a 90% complete JVM implementation that worked. It was a very interesting adventure I want to share with you, download, and have a try.

Requirements

- Python 2.5.X

- JDK 1.6 for compiling

Installation

- Extract the pjvm.zip to your local drive. ex: C:/pjvm

Usage

- Java source files should be in the same application path. ex: C:/pjvm/Main.java

- C:\> cd pjvm

- C:\pjvm> javac Main.java

- C:\pjvm> jvm Main (run my JVM)

It does more than just saying Hello Word, but please keep in mind that I’ve implemented the JVM, not the Java SE. That’s, I did not implement Java SE APIs. For now, you can only use System.out.println() [with the different overloaded versions], and implement threading (using Runnable, do not extend Thread). But for language features, most of them are implemented. That you can declare classes, extend classes, implement interfaces, override and overload methods, define constructors and instance initialization blocks, define instance and static members, define variables and arrays of primitive and reference data types, use control-flow statements, blah blah blah.

Have a try, and thanks for feedback.
