An internal application may be configured to always use a minimum version of the same library. Applications that require no specific version can be configured to use the latest version of the library.

Note:

* Specification-Version (a manifest Attributes for Java EE Libraries)

An optional String value that defines the specification version of the shared Java EE library. Referencing applications can optionally specify a required Specification-Version for a library; if the exact specification version is not available, deployment of the referencing application fails.

The Specification-Version uses the following format:

Major/minor version format, with version and revision numbers separated by periods (such as "9.0.1.1")

Referencing applications can be configured to require either an exact version of the shared Java EE library, a minimum version, or the latest available version.

* Implementation-Version (a manifest Attributes for Java EE Libraries)

An optional String value that defines the code implementation version of the shared

Java EE library. You can provide an Implementation-Version only if you have

also defined a Specification-Version.

* Extension-Name (a manifest Attributes for Java EE Libraries)

An optional string value that identifies the name of the shared Java EE library. Referencing applications must use the exact Extension-Name value to use the library.

As a best practice, always specify an Extension-Name value for each library. If you do not specify an extension name, one is derived from the deployment name of the library. Default deployment names are different for archive and exploded archive deployments, and they can be set to arbitrary values in the deployment command.

* After a library is deployed, the extension-name, specification-version and implementation-version of the library can be found in Administration console.

The Clone WebLogic Domain option launches a wizard that enables you to clone a WebLogic Domain from an existing reference domain that is already discovered with Cloud Control. It allows you to clone the Middleware Home and its binaries, and the domain configuration.

*If you selected the Cloning a WebLogic Domain option, the Middleware Provisioning: Domain Configuration page appears. This page contains a set of links to several pages where you can enter the properties that are most likely to be reconfigured like domain name, listen addresses for the administration server and managed servers, Node Manager/Machine configuration, and JDBC data sources.

The following principles encourage RESTful applications to be simple, lightweight, and fast:

* Resource identification through URI

* Uniform interface: Resources are manipulated using a fixed set of four create, read, update, delete operations: PUT, GET, POST, and DELETE. PUT creates a new resource, which can be then deleted by using DELETE. GET retrieves the current state of a resource in some representation. POST transfers a new state onto a resource. See Responding to HTTP Methods and Requests for more information.

* Self-descriptive messages

* Stateful interactions through hyperlinks
