Java Community Process

From Wikipedia, the free encyclopedia

The Java Community Process or JCP, established in 1998, is a formalized process which allows interested parties to be involved in the definition of future versions and features of the Java platform.

The JCP process involves the use of Java Specification Request (JSR), which are formal documents that describe proposed specifications and technologies to be added to the Java platform. Formal public reviews of JSRs are conducted before the JSR becomes final and is voted on by the JCP Executive Committee. A final JSR provides a reference implementation which provides a free implementation of the technology in source code form and a Technology Compatibility Kit to verify the API specification.

The JCP itself is described by a JSR. As of 2006, the current version of the JCP in use is 2.6 as described by JSR 215.

There are over 300 JSRs. Some of the more visible JSRs are:

[edit] Notes

  1. ^ JSR 3 originally specified the JMX 1.0 release. Two subsequent "final" releases have provided JMX 1.1 and JMX 1.2. JMX 2.0 is specified by JSR 255.
  2. ^ JSR 52 originally specified the JSTL 1.0 release. A subsequent maintenance release provided JSTL 1.1.
  3. ^ JSR 56 originally specified the JNLP 1.0 release. A subsequent "final" release[1] provided JNLP 1.5, which was primarily a maintenance release. As of February, 2006, the JNLP 6.0 maintenance release has been completed but not finalized.
  4. ^ JSR 63 originally specified the JAXP 1.1 release. A subsequent maintenance release of JSR 63 provided the JAXP 1.2 specification.[2] JAXP 1.3 is specified by JSR 206.
  5. ^ JSR 127 originally specified the JSF 1.0 release. A subsequent maintenance release provided the JSF 1.1 specification.[3] JSF 1.2 is specified by JSR 252.
  6. ^ JSR 154 originally specified the Java Servlet 2.4 release. As of February, 2006 a maintenance draft of the 2.5 servlet specification is under review, scheduled to close on March 20, 2006.
  7. ^ JSR 913 originally specified JCP 2.0. It was subsequently amended by various changes to voting rules to produce version 2.1 and then further changed by licensing rules, policy, and processes to get to version 2.5. JCP 2.6 is defined by JSR 215.[4]
  8. ^ JSR 924 originally specified changes to the JVM to support changes in J2SE 5.0. As of 2006 a maintenance update to support changes proposed by JSR 202 is underway.
