• Working at Wells Fargo when I first learned of Java
in 1995
• Joined NetDynamics in 1997
> the first Java application server - proprietary
• Acquired by Sun in 1998
> J2EE standardized the application server space
> Worked on the Reference Implementation
> Joined the tools group in 2005

1995 –
The world
gets to know
about Java in
the form of

5. The Set-Top TV You Never Saw
*7 ("StarSeven")
● Green Team predicted convergence of digitally controlled consumer
devices and computers.
● Produced *7 App aimed at TV set-top box and video-on-demand
industries
● “Oak” processor-independent language for heterogeneous devices
built around networking

6. Computing before Java

Platform

7. To Port Source code
• Some times the source code is portable – One source
can be compiled on different systems – different
flavors of Unix
• But, need to compile and test separately for each
supported platform

8. Java – Portable Code : WORA
Write Once Run Anywhere

10. Java + HTTP

11. Java: Portable code
• Executable portable browser code: Applet
> Stored on Server
> Executed on Client Browser
• Implications
> Platform Independent
> Revolution in Software Distribution

12. Sun
announces
Java and
HotJava at
SunWorld '95.
Netscape
announces its
intention to
license Java for
use in
Netscape
browser.

13. Why did Java become Popular
• Familiar & Simple – like C, C++
• Object-Oriented language
• Portable -
> executes anywhere Java Virtual Machine exists
• Robust, Secure
• Garbage Collection – No memory leaks
• Distributed
> Network Ready

14. Java: Desktop Client Platform
• Java code executes anywhere JVM exists
> Browser
> Operating System
> Chip
• Implications
> Write it once, Run it anywhere
> The language itself is the platform!

Collaborative Information Portal
• Provide a central place to
access mission information
• Provide a Mars time clock
• Navigate, search, and view
mission data, plans, reports and

36. Agenda
• Java
> Java Technology Background & Overview
> J2ME &Java Card
> J2EE & Web Services
> Cool Examples
• Sun and Free Open Source Software
• NetBeans IDE

37. What is Open Source
• Open Source != Open Standards
• Licensed to protect right to...
> Fork
> Modify
> Redistribute
• It's about Community
> Massive peer review means higher overall
quality
> Profit-driven (proprietary) software first exists not
to be excellent, but to make money

38. Sun and Open Source
• Contributed more to the OSS community then any
other vendor

Contributes on many others

41. What's an IDE?
Integrated Development Environment - a set
of tools that aid application development

42. Why Do I Care?
Because IDEs eliminate the tedious parts of
coding, allowing you to focus on solving the
problem.

43. How So?
• By being aware of your code syntax
• By showing errors as you type

44. How So?
• By understanding the Java APIs, even the
one's you create

45. How So?
• By:
>Compiling your code
>Automating repetitive tasks
>Automatically creating classes, methods
and properties
>Providing an interactive debugger
>Refactoring your code
>Integrating with source code repositories
>Integrating with application servers

46. What is NetBeans?
• Free Open Source Pure JavaTM
IDE
• Modular and Extensible
• Supports things you have to pay for in other IDEs
http://www.netbeans.org

47. Where is NetBeans?

48. NetBeans History
• Started in 1996 as a student project at Charles
Univeristy in Prague (originally called Xelfi)
• Most of these same students (now Sun employees)
are still working on NetBeans today.

49. NetBeans History
• The original plan was to develop network-enabled
JavaBeans, hence the name NetBeans.
• In 1999, Sun acquired NetBeans, and briefly
renamed it “Forte for Java”
• In 2000, Sun open sourced NetBeans.
> Although a large contributor to open source projects,
NetBeans was Sun's first sponsored project.
> netbeans.org web site was launched
• In 2001, The Platform was born
> A generic desktop application suitable for any purpose

50. NetBeans 4.1 – It Just Works
• Intuitive User Interface & Usability
• Supports the latest Java APIs (5.0)
• Your Ant script is your project
• Unit testing – a natural part of development
• Integrated CPU & Memory Profiler
• J2ME Mobility Support
• J2EE & Web Services Support
