Why Should Developers Participate?

• "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
Membership Quotes

• 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)
Collaborative Development - How does is work?

• Includes formal public reviews and votes by the Executive
Committee.
• Full Members can submit & lead JSRs, serve on JSR Expert Groups.

The Executive Committee

• We need both!
How: Open Standards & Open Source

• Open source important requirement. So are Standards.
• Coop-edition. 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.
Complimentary

• 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
Open Source Implementations

• New revisions of
each of the three
platforms.
• “JCP.Next” reforms
• Increased
participation from
Community.
