10. In 2017… 50% of tech jobs = technical skills
! Top five key soft skills that engineers and other
professionals should develop for career success.
! Communication
! Creativity/Critical Thinking
! Adaptability/Flexibility

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?

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.
