Topics

• Linux
• Software Choices
• Installation
• Sourceforge.net

5
Linux
6
Linux

• Open source with GNU GPL licensing
• Young and dynamic OS with lots of momentum from
  developers worldwide
• Portable to most architectures
• Diagnostic and tuning packages
• Excellent, low-cost alternative
• Over 18 million Linux users worldwide

7
Why Linux?

• Open source
• You have the source for your OS
• Faster access to patches
• Cost effective. You pay only for support
• Runs on the X86 platform and many others
• Reliable - No blue screen of death

8
Why Oracle on Linux?

• Proven track record
• Technical Linux OS support
• Technology innovations on Linux
• Cost Effective solution
• Certification with major enterprise Linux
  distributions
• 1 million copies of Oracle products for Linux -
  downloaded from OTN

9
Which distribution is for you?

• Red Hat
• SuSE
• Mandrake
• Caldera
• Debian
• Slackware

10
Software Choices

• J2SDK
• CVS
• Editor or IDE
• JDeveloper
• Ant
• Struts
• Tomcat

11
Java2 Software Development Kit

• Which distribution?
• Blackdown.org
• Sun Microsystems, Inc
• Which version
• 1.3.1
• 1.4.1

12
CVS

• Open Source Software Configuration Management
  (SCM) Tool
• Started out in 1986 as a collection of shell
  scripts posted on comp.sources.unix
• CVS application created in 1989
• De-facto standard for SCM among Open Source
  Projects

13
Why CVS?

• Cost effective
• Tested by years of use in many environments
• Client/Server Support
• Supports tunnelling for secure connections
• Extensible with scripts (cvswrappers)

14
Editor or IDE?

• Many Editors
• Emacs
• JEdit
• vi
• Jext
• Many IDEs
• JDeveloper
• JBuilder
• NetBeans

15
Why use an IDE?

• Coding tools geared for your language
• WYSIWYG Editors
• Metadata Editors
• Deployment Support
• VCS Integration
• One tool with a reduced learning curve

16
Ant

• Java and XML based build tool, like make, without
  the quirks
• Included as part of Tomcat source code donated to
  Apache Foundation from Sun
• Split out of Tomcat in January 2000
• Quickly became the defacto-standard among Open
  Source Java projects
• Used by virtually all Apache-Jakarta projects

17
Why Ant?

• Uses XML metafiles instead of make files
• "No dreaded tab problem"
• XML is more familiar to many Java developers
• Extended with Java vs. Shell commands
• Better cross-platform compatibility
• No tcsh/bash/cmd.exe/perl/python required

18
Struts

• Struts is an open source framework for building
  Web applications that integrates with standard
  technologies like Java Servlets, JavaServer Pages
  and JavaBeans
• Struts enables Web application development which
  follow the Model-View-Controller (MVC) design
  paradigm

19
Why Struts?

• Provides a framework for an area where there was
  none
• Struts is already considered the de-facto
  standard for a J2EE MVC Framework
• Struts is moving towards becoming a standard
  (Java Server Faces)
• Is influencing future of J2EE Web Tier
  development

20
Jakarta-Tomcat

• Created when Sun donated the RI to Apache
• Apache Project
• Started the Apache-Jakarta project
• Used by Sun in the reference implementation

21
Installation

• Java2 Software Development Kit
• CVS
• Editors and other free software
• JDeveloper
• Ant and other Jakarta projects

22
Java2 SDK

• Installation Formats
• RPM
• TAR
• Where to install
• Integration with rest of the environment
• Gotachas
• Preferences
• README items do matter

23
CVS

• Where to obtain it
• Where to install it
• Setting up the CVS pserver environment

24
Editors and other free software

• Building from Source
• GNU.org
• SourceForge.net
• Project Home Pages
• Pre-built binaries
• RPMFind.net
• FreshMeat.net

25
JDeveloper

• Free Download from OTN
• http//otn.oracle.com/products/jdev
• RPM and ZIP file installs
• ZIP file is the same image as all platforms

26
Ant and other Jakarta Projects

• http//jakarta.apache.org
• Find a local mirror if possible
• Two ways to install software
• Build it from the sources
• Use the pre-built binaries
• Mix in match pre-built vs. build yourself
• Use pre-built on most Java projects
• Use sources for Apache Server/modules

27
SourceForge.net

• Sourceforge.net is the worlds largest Open
  Source software development website
• Hosts tens of thousands of projects
• Free for all Open Source projects
• Owned by VA Software
• Part of the Open Source Developers Network (OSDN)
