1. 1 Adopt a JSR (Full Presentation) Martijn Verburg (@karianna) James Gough (@JavaJimLondon) On behalf of the LJC and the global JUG program Thanks to SouJava for lots of extra valuable input into this presentation Slide design by http://www.kerrykenneally.comhttp://www.kerrykenneally.com

2. 2 Acronym Soup  JUG - Java User Group  JSR - Java Specification Request  JCP - Java Community Process  RI - Reference Implementation  TCK - Technology Compatibility Kit

3. 3 What is the Adopt a JSR program?  See http://adoptajsr.org for full detailshttp://adoptajsr.org  A JUG lead initiative to improve standards in the Java ecosystem  Groups of JUG members work on Java Specification Requests

4. 4 Why should the JUGs get involved? - 1  To move the entire Java ecosystem forward –To become part of the solution as opposed to staying silent –Help define the future  To be at the forefront of new technology  To ensure that ivory tower standards do not occur  To make sure the useful libraries and APIs get built  To boost the careers of JUG members –Gain new technical and community skills and much more!new technical and community skills

5. 5 Why should the JUGs get involved? - 2  To demystify the JCP and the standards process –Get day to day developers knowledgable about the process  To acquire new knowledge –Gain valuable technical skills –Learn a brand new part of the Java ecosystem  To gain competitive advantage –Be the early experts in a new standard  Gain more members –Helps build long lasting activities for the JUG –Turns passive members into active ones!  It’s fun! 5

6. 6 How does it help the Standards?  Standards get earlier feedback –Leading to more developer friendly APIs  Standards get 'end user/developer' expert input  Standards get developed more quickly, JUGs can help build –Reference Implementations (RI) –Technical Compatibility Kits (TCK)  JUGs can also help with management of the JSR –Managing mailing lists –Triaging issues –Testing –Evangelism –+ more! 6

7. 7 Who’s involved already?  See http://adoptajsr.org for up to date details.http://adoptajsr.org –The London Java Community (UK) –SouJava (Brazil) –GoJava (Brazil) –Houston JUG (USA) –Chennai JUG (India)  + Several more starting out 7

8. 8 What difference have they really made?  SouJava helped push through JSR-348 –Reforming the Java Community Process (JCP) –Open mailing lists –Public Issue trackers –Standards reviewed early and often  The LJC is helping make sure JSR-310 gets through –Date and Time for Java 8 –Focussed on building the Technology Compatibility Kit (TCK) –~40% by Dec 2011 –Ensures that you get the new Date and Time API for Java 8  Houston JUG is working on Data Grids –Vital technology for the cloud space –Avoids vendor lock-in 8

9. 9 How do I join?  Contact your local JUG leader  OR  Go to http://adoptajsr.orghttp://adoptajsr.org –Follow the simple set-up steps there 9

10. 10 An Important Note  Your enthusiasm and skill sets are what JSRs need!  But your efforts should have focus – Sometimes well meaning enthusiasm can be counter productive – e.g. We’re not all language designers! – However, there is always a truly productive way to help a JSR  Don’t forget, co-ordinate and communicate your efforts – With the Spec Lead and the Expert Group – With other JUGs  http://java.net/projects/jugs/pages/AdoptAJSR#Laser-like_focus http://java.net/projects/jugs/pages/AdoptAJSR#Laser-like_focus 10

11. 11 Steps to take after joining  Find fellow members in your JUG to work with –A particular JSR might already have members in your JUG working on it –Double check the matrix at http://adoptajsr.org http://adoptajsr.org  Join the relevant JSR mailing list  We encourage people/groups down two paths –Scratch an itch. Work on the part of the JSR you’re interested in! –Spec lead guidance. Simply ask the Spec lead what needs done!  The next few slides have suggested ideas  Don’t forget to have fun! 11

12. 12 Starter Levels to get involved at - 1  Test the early RI builds –Use them to find pain points (“It’s just too laborious to construct X”) –Report bugs (“Arggh NPE!!”) –Suggest feature enhancements (“A convertX method would help”)  Help triage issues –Reproduce issues –Erase/merge duplicates –Set priorities/categories etc  Give feedback on design –Discuss issues with your JUG and deliver feedback –Think about how you would use the JSR as a –day to day developer 12

13. 13 Starter Levels to get involved at - 2  Help moderate the mailing lists –Help the community self police towards helpful conversations –Pour water on flame wars etc  Help evangelise the JSR –Social media (twitter, facebook et al) –Blogging (write a post about the JSR) –Lightning talks (give a talk at your user group or online!)  Improve project infrastructure and JSR visibility –Help setup canned hosting (java.net, GitHub etc) –Help with SEO of website –Ensure downloads, mailing lists, issue trackers are easy to find –Help maintain their FAQ/Wiki 13

14. 14 Intermediate Levels to get involved at  Help get the JSR to JSR-348 compliance –Is there a public issue tracker? –Does the EG communicate on a public mailing list? –Is the EG balanced? –Is the Std a coming together of competing implementations?  Help build the RI –Get coding with the actual implementation of the spec!  Help build the TCK –All implementations must pass this crucial test suite –Great way to gain real TDD/Unit/Integration test experience 14

15. 15 Advanced Levels to get involved at  Join the Expert Group (EG) –You need to be an expert in this technology –EG members are central to pushing the JSR forwards –High time commitment –Lots of personal, community and career benefits  Become the Spec Lead for a JSR –You need to be a leading expert in a particular technology –Considerable time commitment –International recognition for your work  Join the Executive Committee –High time commitment, influence all standards 15

16. 16 Starting an ‘Adopt a JSR’ group  http://java.net/projects/jugs/pages/AdoptAJSR#Leading_an_Adopt_ a_JSR_group http://java.net/projects/jugs/pages/AdoptAJSR#Leading_an_Adopt_ a_JSR_group  Set up a wiki page to co-ordinate your activities –e.g. http://java.net/projects/ljc-london-jug/pages/JSR-310http://java.net/projects/ljc-london-jug/pages/JSR-310 –Link that into the matrix at http://adoptajsr.org http://adoptajsr.org  Contact the Spec Lead / EG  Mail your JUG members to gather interest –Outline what this JSR is and why the JUG should get involved  Identify areas that you and your members want to work on –Best to co-ordinate this with Spec Lead 16

17. 17 Lets change the Java ecosystem!  Thanks for reading! –The acronyms become familiar, we promise!  We really hope you’ll consider joining us –Duke would love your help!  http://adoptajsr.org for full details http://adoptajsr.org  Contacts: –Martijn Verburg (@karianna) –James Gough (@JavaJimLondon) 17
