Overview

You can associate shared libraries with the class loader of a server. Classes represented by the shared library are then loaded in a server-wide class loader, making the classes available to all applications deployed on the server.

This topic assumes that you have defined a shared library. The shared library represents a library file used by multiple deployed applications. To associate a shared library with the class loader of a server, create and configure a library reference using the console. A library reference specifies the name of the shared library file.

If you associate a shared library with a server class loader, do not associate the same shared library with an application.

 

Procedure

  1. Configure class loaders for applications deployed on the server.

    1. Click...

      Servers | Application Servers | server_name

      ...to access the settings page for the appserver.

    2. Set values for the application Class loader policy and Class loading mode of the server.

      For information on these settings, see...

  2. Create a library reference for each shared library file that your application needs.

    1. In the console, click...

      Servers | Application Servers | server_name | Java and Process Management | Class loader | class_loader_ID

    2. Click Shared library references to access the Library Reference page.

    3. Click Add.

    4. On the settings page for a library reference, name the library reference. The name identifies the shared library file that your application uses.

    5. Click Apply. The name of the library reference is shown in the list on the Library Reference page.

    Repeat the previous steps until you define a library reference for each shared library that your application needs.
