A WebLogic Shared Library is an Enterprise Application Archive, a stand-alone EJB, a Web Application module, or a JAR file that is registered with Oracle WebLogic Server as a shared library. The library resources can be shared between multiple applications, alleviating the need to have duplicate copies of the resources in each application. For an overview of WebLogic Shared Libraries, see Oracle WebLogic Server: Overview of the J2EE Library.
Library reference: WebLogic Shared Libraries
are referenced indirectly by specifying the name of the library, the specification
version (optional), the implementation version (optional) and whether a newer
version of the library should be used if present. The library references
are used on the project classpath and in the deployment descriptors (weblogic-application.xml
and weblogic.xml). Library references are resolved against the libraries
registry when necessary.
Libraries registry (or registry):
The list of known WebLogic Shared Libraries which is used to resolve a library
reference. Using Eclipse IDE, you can view and modify the registry from the workspace preference page by selecting Window > Preferences
> WebLogic
> Shared Libraries from the top menu.
At run time, the registry is described in the domain's config.xml file.
