7. JAVA
Based on C++
Sun introduced in May 1995
World Wide Web caused immediate interest
Object Oriented Language
Achieves modularity through the use of Classes and Methods

8. JAVA
Classes and Methods may be programmer defined
The Java Class Library or Java API provides predefined
Classes and Methods
Example:
The Math Class provides several mathematical methods
such as:
 Abs (x)
 Min (x,y)

9. JAVA
 //a simple Java program which defines class Welcome, and
has only one method
 Import java.applet.Applet; //imports the Applet class
 Import java.awt.Graphics //imports the Graphics class
 Public class Welcome extends Applet {
 Public void paint( Graphics g )
 {g.drawstring( “Welcome to Java Programming”, 25, 25 );}
 }

10. JAVA
Five phases to execute program:
Edit => save as Welcome.java
Compile => javac Welcome.Java creates Welcome.class
Create HTML file which includes applet called Welcome.class
Load => user’s browser will load Welcome.html file
Verify => verifies that Welcome.class applet does not violate
Java security
Execute => java interpreter within user browser executes
Welcome.class applet

11. JAVA
Network Delivered Functionality
Java Applet is stored on Server, not on client
Client needs only a Java supported browser to execute applet
within Server html file
Client does not need Java installed locally
Demonstrates power of Java:
Ability to provide network delivered functionality

12. JAVA BEANS
Reusable software components written using Java.
Allows code to be shared beyond one platform, one
architecture (distributed systems).
“Write Once, Run Anywhere”

13. JAVA BEANS
Allows applications to be assembled, rather than coded in the
classical monolithic style.
Embraces internet and addresses Client/Server deployment/
maintenance issues via “thin-client”.
Device independent. Supported on Mainframes, PCs,
Network Computers, cellular phones, PDAs.

14. BEAN FEATURES
Introspection - builder tool can automatically analyze how a
bean works
Customization - ability to customize appearance and behavior
of a bean
Events - enables connection and communication between
Beans.
Properties - enables customization of Beans.
Persistence - Storing of data across sessions.

15. ENTERPRISE JAVA BEANS
Model for the development and deployment of reusable Java
Server components.
API specification for building scalable, distributed,
component based, multi-tier applications.
First released to public March of 1998.

16. ENTERPRISE JAVA BEANS
Concerned with “Server-Side” portion of business
applications.
Maps communication among components to underlying
protocols such as CORBA (Component Object Request
Broker Architecture) and IIOP (Internet InterORB
Protocol).
Transactional perspective.

17. ENTERPRISE JAVA BEANS
Provides typically application server functions:
start, commit/rollback, security, database access
Designed to be layered on top of existing IT systems.
EJB Servers available in 1998
BEA WebLogic Tengah
IBM WebSphere Advanced Edition
Oracle Application Server

18. ENTERPRISE JAVA BEANS

21. WEB-ENABLED DATA
WAREHOUSING
NEED FOR WEB-ENABLED DATA WAREHOUSING
Increased demands on IT Departments for reports and
information
Outside access for customers
Outside access for mobile users

22. WEB-ENABLED DATA
WAREHOUSING

Better customer support / lower cost
More use of the data warehouse
Better understanding of data by end users
More sophisticated queries
Diminished need to extend corporate networks
Simplified system administration
Increased opportunity to outsource

23. WEB-ENABLED DATA
WAREHOUSING
HOW COSTS ARE CUT
