Java EE Library: Targets

Related Tasks     Related Topics

Use this page to select the WebLogic Server instances and clusters to which you want to deploy (target) the Java EE library.

The Java EE library feature provides an easy way to share one or more types of Java EE modules among multiple Enterprise Applications.

In particular, a Java EE library is a stand-alone 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 Java EE application container upon deployment.

After the library has been registered, you can deploy Enterprise Applications that reference the library. Each referencing application receives a reference to the required library module(s) on deployment, and can use those modules as if they were packaged as part of the referencing application itself. The shared library classes are added to the classpath of the referencing application, and the referencing application's deployment descriptors are merged (in memory) with those of the Java EE library modules.

The name of the Java EE library is always followed by a version number of the form (Specification@Implementation), where Specification identifies the version number of the specificaiton (for example, the Java EE specification number) to which a library or package conforms and Implementation identifies the version number of the actual actual code implementation for the library or package. This versioning of Java EE libraries enables referencing applications to specify a required minimum version of the library to use, or an exact, required version.
