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

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.
