Advance your Career and Help Define Java’s Future
0 likes226 views
This document discusses ways for developers to get involved in shaping the future of Java through participation in the Java Community Process (JCP). It outlines the JCP's structure and processes for developing Java specifications through JSRs. It encourages developers to get involved by commenting on specifications, trying implementations, evangelizing technologies, and participating in hack days and open source projects. Participation can help developers advance their careers through skills growth, visibility, and giving back to the community.

- 15. Membership Quotes ! "Joining the JCP, especially being a member of several expert groups, has had a big impact on my career. Mostly by making it visible for the leadership and managers in my company that I am actually a part of forming the future of the platform. I also think, or hope, that it is an inspiration for my colleagues." - Ivar Grimstad ! "Joining the JCP is like being a Java citizen." - Heinz Kabutz
- 16. Collaborative Development - How does is work? • Java Specification Requests (JSRs) • A JSR is a single version of a Java specification. • JSRs are led by a community member (the Spec Lead), with a group of interested members (the Expert Group) helping with the day-to-day decisions and work. • Any JCP member can submit and lead a JSR. • Each Expert Group must deliver: • The Specification • A Reference Implementation (RI) • A Technology Compatibility Kit (TCK) •. 16
- 17. The JSR Development Cycle •Includes formal public reviews and votes by the Executive Committee. •Full Members can submit & lead JSRs, serve on JSR Expert Groups. •See the Process Document for the details. 17
- 18. Compatibility Triangle Can you build an implementation? Is the specification unambiguous? Is the TCK correct? Does the RI conform? 18

- 24. How: Open Standards & Open Source ! We need both! 24
- 25. Complimentary •Open source important requirement. So are Standards. • Coop-etition. Agree on what to standardize (cooperation) & what to compete on (implementations). •Open standards implemented in open source = easier to implement standard & for developers to understand technology. • Results in more implementations and greater adoption of the standard. •An effective way to develop a standard-start with an open source project that has demonstrated the need for standardization. •. 25
- 26. Open Source Implementations •The Reference Implementations of the Java SE and Java EE platforms are also developed collaboratively and released under open-source licenses. –Java SE: OpenJDK –Java EE: Project GlassFish 26
- 27. How •New revisions of each of the three platforms. • “JCP.Next” reforms . •Increased participation from Community. Organization Focus 27
