Introduction to Java
---------------------
Java is a programming language created by James Gosling from Sun Microsystems in 1991. The first publicly available version of Java (Java 1.0) was released in 1995.
Over time new enhanced versions of Java have been released. The current version of Java is Java 1.7 which is also known as Java 7.
From the Java programming language the Java platform evolved. The Java platform allows software developers to write program code in other languages than the Java programming language and still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.
1.2. Java Virtual machine
-----------------------------
The Java virtual machine (JVM) is a software implementation of a computer that executes programs like a real machine.
The Java virtual machine is written specifically for a specific operating system, e.g. for Linux a special implementation is required as well as for Windows.
Java programs are compiled by the Java compiler into bytecode. The Java virtual machine interprets this bytecode and executes the Java program.
1.3. Java Runtime Environment vs. Java Development Kit
------------------------------
A Java distribution comes typically in two flavors, the Java Runtime Environment (JRE) and the Java Development Kit(JDK).
The Java runtime environment (JRE) consists of the JVM and the Java class libraries and contains the necessary functionality to start Java programs.
The JDK contains in addition the development tools necessary to create Java programs. The JDK consists therefore of a Java compiler, the Java virtual machine, and the Java class libraries.
1.4. Characteristics of Java
------------------------------
The target of Java is to write a program once and then run this program on multiple operating systems.
Java has the following properties:
------------------------------
Platform independent: ::: Java programs use the Java virtual machine as abstraction and do not access the operating system directly. This makes Java programs highly portable. A Java program (which is standard complaint and follows certain rules) can run unmodified on all supported platforms, e.g. Windows or Linux.
Object-orientated programming language:::: Except the primitive data types, all elements in Java are objects.
Strongly-typed programming language: Java is strongly-typed, e.g. the types of the used variables must be pre-defined and conversion to other objects is relatively strict, e.g. must be done in most cases by the programmer.
Interpreted and compiled language: Java source code is transferred into the bytecode format which does not depend on the target platform. These bytecode instructions will be interpreted by the Java Virtual machine (JVM). The JVM contains a so called Hotspot-Compiler which translates performance critical bytecode instructions into native code instructions.
Automatic memory management: Java manages the memory allocation and de-allocation for creating new objects. The program does not have direct access to the memory. The so-called garbage collector deletes automatically objects to which no active pointer exists.

Introduction Of JDBC
===============
The JDBC ( Java Database Connectivity) API defines interfaces and classes for writing database applications in Java by making database connections. Using JDBC you can send SQL, PL/SQL statements to almost any relational database. JDBC is a Java API for executing SQL statements and supports basic SQL functionality. It provides RDBMS access by allowing you to embed SQL inside Java code. Because Java can run on a thin client, applets embedded in Web pages can contain downloadable JDBC code to enable remote database access. You will learn how to create a table, insert values into it, query the table, retrieve results, and update the table with the help of a JDBC Program example.
Although JDBC was designed specifically to provide a Java interface to relational databases, you may find that you need to write Java code to access non-relational databases as well.
------------------------------
Introduction of J2EE
============
The J2EE Architecture allows the programmers to divide their work into two major categories Business Logic and Presentation Logic. J2EE Architecture The J2EE Architecture allows the programmers to divide their work into two major categories:
Presentation Logic:
Presentation Logic consists of all the program (JSP and Servlets), images and html files that are used to interact with the client. These files are archived into .war file. These files are installed on the web server and these interacts with the users.
Business Logic:
These are EJB applications which implements the business logic of the system and are archived into .jar file. Business logic runs on the application server.
These two types of archives are bundled into complete J2EE applications, and delivered as Enterprise Archive (EAR) file.
==============================
Introduction To Enterprise Java Bean(EJB)
------------------------------
Enterprise Java Bean architecture is the component architecture for the development and deployment of robust, world class component-based distributed application using the java language. EJB is a complex topic and requires a lot of effort to master it.
==============================
What is Struts?
-----------------
Struts is a popular open source framework from Apache Software Foundation to build web applications that integrate with standard technologies such as Servlets, Java Beans and Java Server pages(JSP).
Struts offers many benefits to the web application developer,including the Model-View-Controller (MVC) design patterns (best practice) in web applications.
Model that represents the data layer, a view layer that represents the data processed by the model component; and a Controller component that is responsible for interaction between the model and the controller.
==============================
What are JavaServer Pages?
------------------------
JavaServer Pages (JSP) is a technology based on the Java language and enables the development of dynamic web sites. JSP was developed by Sun Microsystems to allow server side development. JSP files are HTML files with special Tags containing Java source code that provide the dynamic content.
==============================
What are Servlets?
------------------------
A Servlet is a Java class that provides special server side service. To display any information on a web page,HTML code is embedded in “println” statements. JSP technology is an extension of Servlets. It is easier to generate GUI pages using JSP because a web page editor (such as Macromedia DreamWeaver ) can be used to create simple pages.
==============================
What are Enterprise JavaBeans?
------------------------------
Enterprise JavaBeans (EJB) provides a component specification for the development of scalable and secure middleware components. The EJB Server handles security and transaction management details so developers can focus on implementing the business logic.
==============================
Introduction to Spring Framework
------------------------------
Spring Framework is a Java platform that provides comprehensive infrastructure support for developing Java applications. Spring handles the infrastructure so you can focus on your application.
==============================
Introduction to Hibernate
-----------------------------
Hibernate is an open source object/relational mapping tool for Java. Hibernate lets you develop persistent classes following common Java idiom - including association, inheritance, polymorphism, composition and the Java collections framework.
