A J2EE library is a standalone EJB or Web Application module,
multiple EJB or Web Application modules packaged in an Enterprise
Application (EAR), or a single plain JAR file that is registered with
the J2EE application container upon deployment. After the library has
been installed and started, other deployed modules can reference the

The name of the J2EE library is always followed by a version of
Specification identifies the version number

to which a library or package conforms and
Implementation Identifies the version number
of the actual code implementation for the library or package. This
versioning of J2EE libraries enables referencing applications to
specify a required minimum version of the library to use, or an
