Java EE6 - Profiles

Profiles

 

The Java EE 6 specification introduces the notion of “profiles”:

A profile is a sub-set of Java EE APIs geared towards a particular class of applications in mind (for e.g.: Web Profile - see below).

Web Profile

A separate specification, the Java EE 6 Web Profile Specification, defines the Java EE Web Profile, the first new profile of the Java EE 6 platform.

The Java EE Web Profile only include APIs that are likely to be used in most Java web applications.

Although Java EE 6 defines the rules for creating new Profiles through separate JSRs, only one Profile, the Web Profile is included in platform this time.

Additional profiles may be defined in accordance with the rules of the Java Community Process.
