We blend along with the current industry standards and makeovers

This series of bare bone examples with screenshots would abound the following themes.

1. Pre Requisites, Installation and the use of different IDEs.
2. Java Web-Application: containing all markup languages and dynamic web components like Servlet, JSP, JavaBeans etc.
3. Java EE: will include codes and code snippets which will be used to develop rich client server applications. This section will cover Web services, EJB, Persistence and other APIs.

JEE : Java Enterprise Edition

We felt that to understand JEE better, understand it's targeted platforms or the purpose behind the APIs.

• Let Servlet services serve the client.
  • Design Servlet centric application with request and response.
• Considering Component
  • Java Bean resides in JVM
    • must reside in the same JVM as the client and server
  • Enterprise Java Bean (JB)
    • Distributable component
    • understand request, session
    • can reside different JVM allowing a client be separated form the server and be placed in a different machine.
• Developing business logistics as a middle layer
  • (being updated )
• And so on: please refer to JEE API listed below.

 

What is Java EE?

Java Enterprise Edition( JEE or J2EE) is a  platform containing many web  API for developing, deploying, creating web-services, managing multitier and server-centric applications. The Java EE API relies on the  Java SE platform and provides numerous  APIs for developing portable, dynamic, robust, scalable, reliable and secure server-side applications.

Some of the fundamental components of Java EE include:

J2EE & JEE Ref : http://java.sun.com/javaee/

" The name of the Java platform for the enterprise has been simplified. Formerly, the platform was known as Java 2 Platform, Enterprise Edition (J2EE), and specific versions had "dot numbers" such as J2EE 1.4. To strengthen the association with the Java platform, the short name is now Java EE, and to simplify the version number, the leading "1." is dropped. So the latest version of the Java platform for the enterprise is Java Platform, Enterprise Edition 6 (Java EE 6). " 

New Features (New Over the Old, a quick glimpse)

• EJB 2.x has been simplified and substituted with EJB 3.0
  • EJB CMP is removed
• Web Beans would address the anarchies in EJB, JTA, JPA
• Servlet 3.0 , JPA 2.0
  • using annotations instead of XML
  • Web-fragments
• JPA 2.0 simpler than JPA 1.0

There are two Java EE 6 SDK versions:

• Java EE 6 SDK
• Java EE 6 Web Profile SDK

These SDK versions support the latest technologies of the Java EE 6 Specification.

Many graphical updates, remodeled and many tools to consider

Java mist or fog is clearing up with new-facelifts by Oracle corporation.

• GUI :
  • Text Pad 5.x, a road warrior's concealed editor.
  • Old buddy Eclipse, PHP, JEE or C++ all you can plug in or out.
  • NetBeans with a power of a studio-software; Java, JEE or PHP, choice is yours
• Many database choices
  • Oracle Express
  • Oracle 10g, 11g (  big muscles)
  • MySQL and SqlLite ( Slick databases )
• Create, view  web applications before deploying.
  • Deploying way easier than before, jar or war, both are tasty bundles. 
  • Pick Tomcat , JBoss, GlassFish, for windows or Linux, whether  64 by 32, all scalable
