3. IBM Software Group | WebSphere software Free Software versus Open Source  Free software is a matter of liberty not price. You should think of “free” as in “free speech”, not as in “free beer”. (http://www.fsf.org/)http://www.fsf.org/  Perceived drawbacks to Free Software  Confusion as to it’s definition Googling for free software returns many different things http://www.fsf.org/licensing/essays/free-sw.html  Licensing “Copy left” requirement  Lack of quality Unknown pedigree Scalability, serviceability, reliability, localization, … Largely unfounded  Not attractive to commercial enterprises “Open source is a development methodology; free software is a social movement”

4. IBM Software Group | WebSphere software What is Open Source  Open Source Initiative (OSI) maintains a formal definition of Open Source Software (OSS) recognized by the open source community. OSI has a web site at: http://www.opensource.org  Open Source Definition current criteria (paraphrased):  Free Redistribution  Source Code  Derivative Works  Integrity of The Author's Source Code  No Discrimination  No Discrimination Against Fields of Endeavor  Distribution of License  License Must Not Be Specific to a Product  License Must Not Restrict Other Software  License Must Be Technology Neutral The basic idea behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.

5. IBM Software Group | WebSphere software Open Source Development Methodology  Virtual community of programmers, leveraging the Internet for communication, who create / debug / maintain / evolve a source code base  OSS projects often self-organizing:  Someone determines a need and communicates that need to others on the Internet  If the project generates interest, one or more programmers begin writing code  Someone takes a leadership role and begins to map out a project road map  Interested programmers join the project to contribute new code or fine-tune existing code  A network of participants, linked via the Internet, forms  Tiered participation levels emerge

6. IBM Software Group | WebSphere software IBM and Open Source  IBM has contributed many projects to the open source community  Eclipse Project: http://www.eclipse.orghttp://www.eclipse.org Project dedicated to providing a robust, full-featured, commercial- quality, industry platform for the development of highly integrated tools  Apache Derby: http://db.apache.org/derbyhttp://db.apache.org/derby Database management system developed by the Apache Software Foundation  Linux Technology Center (LTC): http://www.ibm.com/linuxhttp://www.ibm.com/linux Work towards Enterprise enablement of the Linux OS through the development and contribution of technology, utilities, tools and code  Other contributions  IBM Pledges 500 U.S. Patents To Open Source In Support Of Innovation And Open Standards

7. IBM Software Group | WebSphere software IBM and Open Source  IBM uses open source in its products  Building products on top of open source projects e.g. Rational Application Developer  Apache webserver to support and bundle with its WebSphere suite  IBM promotes open source development  Externally AlphaWorks: http://alphaworks.ibm.comhttp://alphaworks.ibm.com DeveloperWorks: http://www- 130.ibm.com/developerworks/opensourcehttp://www- 130.ibm.com/developerworks/opensource  Internally Using open source intranet site to promote software componentization and reuse

9. IBM Software Group | WebSphere software Java Tooling  From www.eclipse.org...www.eclipse.org  “Eclipse is an open source community whose projects are focused on providing an extensible development platform and application frameworks for building software.”  Put more simply...  Eclipse is an Open Source Java IDE  And so much more....  Multiple languages (Java, C++, COBOL)  Debugger  Unit Testing  Modelling with UML  Visual Editing of Java UI  Java Web Tools (JSP, EJB, XML....)  All through an extensible plugin-based IDE

10. IBM Software Group | WebSphere software Eclipse Project Aims  Provide open platform for application development tools  Run on a wide range of operating systems Windows, Linux, AIX, MacOS X, etc. GUI and non-GUI components  Language-neutral  Able to handle different content types  Java, HTML, C/C++, JSP, EJB, XML, GIF, etc.  Facilitate seamless tool integration  At UI and lower level  Add new tools easily  Attract community of tool developers  Including independent software vendors (ISVs)  Capitalize on popularity of Java for writing tools

11. IBM Software Group | WebSphere software Why develop plugins that extend Eclipse ?  Infrastructure  You get a workbench created for free – just add what you need  No need to create an environment from scratch  Build on Eclipse Modelling Framework (EMF) for model support  Build on Graphical Editing Framework (GEF) for graphics support  Interoperability  Use any of the existing tools in your ‘end-product’ Java Editor, outliner... Explorer, Text editor, search... etc.  Examples  Java (or any language) code analysis/transformation plugins  Any UML related tooling (using EMF)  Any Java graphical projects (using GEF)

12. IBM Software Group | WebSphere software Java Perspective  Java-centric view of files in Java projects  Java elements meaningful for Java programmers Java project package class field method Java editor

13. IBM Software Group | WebSphere software Java Editor Lots of useful features such as....  Method completion in Java editor List of plausible methodsDoc for method

14. IBM Software Group | WebSphere software Top 10 Tips for Eclipse Users  Use Code Assist  Just press the code assist key combination (by default ctrl-space) and the IDE will either fill in where you’ve started typing or display a menu.  Navigate Through Code By ctrl-Clicking  You can move to a field, method, or class by holding down the ctrl key and clicking on the identifier you’re interested in.  Quickly Open Classes and Resources by Name  To open a Java class, press ctrl-shift-T. This will display a dialog box that allows you to type in a class name.  Set the Heap Size  Eclipse is a large, complex, Java-based IDE. It needs lots of memory to perform well.  eclipse -vmargs –Xmx1024M

15. IBM Software Group | WebSphere software Top 10 Tips for Eclipse Users  Configure Eclipse To Use a JDK, not a JRE  Go to Window -> Preference -> Java -> Installed JREs  Use a JDK that supports hot code replace (IBM J9 or JDK 1.4.1+)  Use the Eclipse’s Refactoring Support and Code Generation  Eclipse also has extensive support for code generation.  Use Multiple Workspaces Effectively  A workspace is a container of projects that has its own set of preferences and metadata.  eclipse –data c:\myworkspace –showlocation  Use Templates  Open a Java class in an editor, type in “sysout” and press ctrl-space.  Set Type Filters  If you’re seeing classes show up at the top of your search you know you’re not interested in, filter them out for faster searching.

16. IBM Software Group | WebSphere software Top 10 Tips for Eclipse Users  Know the Keyboard Shortcuts  ctrl-shift-o: organize imports  ctrl-shift-F4: closes all open editor windows  ctrl-o: outline popup – very useful for quickly jumping to a method in a large class  f4: shows the hierarchy viewer for a class (ctrl-T shows similar data in a popup version)  ctrl-m: toggle maximize of the current editor or view  ctrl-F11: run the last launched configuration
