    • Desktop systems

    • Servers

    • Network connectivity

    • Data Warehousing

    • Peripherals


Business principle l.jpg
BUSINESS PRINCIPLE

  • MULTI-VENDOR SOLUTIONS

    • Teams with software vendors

    • Brings Java and computing platform to the partnership

    • Business partners

      • Sun and Informix

      • Sun and Netscape


Slide7 l.jpg
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


Slide8 l.jpg
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)


Slide9 l.jpg
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 );}

  • }


Slide10 l.jpg
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


Slide11 l.jpg
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


Java beans l.jpg
JAVA BEANS

  • Reusable software components written using Java.

  • Allows code to be shared beyond one platform, one architecture (distributed systems).

  • “Write Once, Run Anywhere”


Java beans13 l.jpg
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.


Bean features l.jpg
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.


Enterprise java beans l.jpg
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.


Enterprise java beans16 l.jpg
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.


Enterprise java beans17 l.jpg
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


Enterprise java beans18 l.jpg
ENTERPRISE JAVA BEANS

  • Additional EJB Servers expected from:

    • Fujitsu

    • Informix

    • Netscape

    • Sun

    • Sybase
