Published: Saturday, 23 March 2013

Java Specification Requests (JSR) are formal documents that specify APIs in the Java platform.

It may take a long time before any of the APis become a standard part of that platform, so in the meantime you should be able to include JARs in your project that implement specific JSRs or APIs.

e.g. JSR 356 is a proposed standard for WebSockets.

JSR 250 introduces some helpful annotations found in the javax.annotations package.
