The document discusses Java Enterprise Paradise and the benefits it provides. It describes how J2EE addresses issues with traditional J2SE development like managing large amounts of data and connections. J2EE introduces a multi-tier architecture with client, web, business and enterprise tiers. It allows for integration, scalability, distributed systems and mobile access. Popular J2EE application servers and frameworks are also covered, along with examples of complex applications developed for telecom and other industries.

 Data amount
 Database Connection
 Network Connection
 Manual Transactions
 Every one has a software on his desktop
 Every one has separated Database

7. Java Enterprise tiers
7
 Focus On business Logic
 Multitier Architectures :
 Client Tier .
 Web Tier.
 Business Tier .
 EIS Tier .
 Mobile view
 Web Services
It’s Data What is moving us

8. Client Tier
8
Runs On Client Machines .
Web Application
• Dynamic web pages generated by web component ( JSP & Servest ).
Application Client
• provides a way for users to handle tasks that require a
richer user interface than can be provided by a markup
language ( GUI, => Swing, AWT).

9. Web Tier
9
Run on Web Server ( a part from J2EE Server ) to generate
Dynamic Content .
Servlets
• Java Classes that process request and construct response .
JSP ( Java Server Pages )
• Text-based Documents that executes as Servlets , but allow more
natural approach .
JSF ( Java Server Faces )
• Provide UI component framework for Web Application above JSP &
Servlets .

10. Business Tier
10
Runs on EJB Server ( as a part from J2EE server ) to
expose Business Logic to third party applications.
EJB Technology
MSG-Driven Beans
• Allow Business Component to send and receive Massage asynchronously
Session Beans
• Represent a transient conversational with Client .

11. EIS Tier
11
Enterprise Information System
EIS SW and Enterprise Infrastructure
• Handles Enterprise information System Software and Include
Enterprise Infrastructure System .
Enterprise Infrastructure System likes :
• Database Systems .
• Legacy Information Systems .

12. J2EE features
12
Some frameworks support more
features
Mobile and IPad View
• ADF supports some libraries for Mobile and IPad View
Web-Services
• Application Based on SOA .

13. J2EE IDEs
13
 Integration Development Environment
 We can use what ever Java IDE to Develop
Enterprise Application using any framework .
 BUT each IDE help well on some frameworks
 Netbeans : EJBs, JSP & Servlet .
 Eclipse : Spring, Build tools .
 Jdeveloper : ADF, Fusion Application, JSF .
 WPS and RDA : JSF Based on IBM Implementation

14. Application Servers
14
 Application Server : Software and Hardware
acting together to server Customer into
Enterprise Environment .
 Application servers types
 JBOSS has developed by REDHAT
 OC4G, Oracle AS and has developed by
ORACLE .
 Weblogic bought and developing now by
ORACLE .
 ORACLE now uses WEBLOGIC as default AS .
 Websphere has developed by IBM .

15. Clustering and J2EE
15
Deployment
 Clustering : collection more than one server as
One Server to serve Customer in highly,
efficiency and quickly .
 Deployment : We can deploy One Application
On different Servers and using different
database by edit configuration without any
coding .

16. J2EE Application for Customer
16
 Telecom Applications
 Ministries and Banks Systems
 Websites and Portals
 Application based on SOA Technology
It’s Data What is moving us

17. Telecom Applications
17
 Vodafone Promo system :
 Get All Phone calls per hour ( almost from 1 million – 3
millions record)
 Each record represent a call
 Calculate each call cost according to
 Source and destination .
 Customer business promo
 Time Call
 May has One Promo or TWO promos
 Send a message to system to decrease call cost from
charge
 Send a Message to the customer about call Cost .

18. J2EE Application for
18
Developers
 Some companies specialist in Product
Services uses J2EE to Develop some
frameworks to help J2EE users in creating
EJBs, Beans and UI easily and let them
focusing more on business logic .

19. Frameworks
19
Java Server Faces - JSF
Spring Framework
Application Development
Faces - ADF
It’s Data What is moving us

20. Servers

 These companies developed more than
frameworks.
 They Developed some servers to serve
customer
Into some complex issues like ( archiving,
WF,…)
