Configure a J2EE library

A J2EE 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 J2EE application container upon deployment. After the library has been installed and started, other deployed modules can reference the library.

The following procedure describes how to update the configuration of an already-installed J2EE library.

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the left pane of the Console, click the Deployments folder. A table that lists all the deployments currently installed to WebLogic Server appears in the right pane. J2EE libraries are specified by the Library entry in the Type column.
  3. In Deployments table, click the name of the J2EE library you want to configure.
  4. Click the Overivew tab to view, and sometimes change, general configuration information about the J2EE library, such as its name, path to the source of the application, and staging mode. Use the Deployment Order field to change the order that the library is deployed at server startup, relative to other deployments.

    The name of the J2EE library is always followed by a version of the form (Specification@Implementation), where Specification identifies the version number of the specification (for example, the J2EE specification version) 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 exact, required version.

  5. Click Save to save your changes.
  6. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
