Associating shared libraries with applications or modules

You can associate a shared library with an application or module. Classes represented by the shared library are then loaded in the application's class loader, making the classes available to the application. This topic assumes that you have defined a shared library. The shared library represents a library file used by multiple deployed applications.

You can define a shared library at the cell, node, or server level.

This topic also assumes that you want to use the administrative console, and not an installed optional package, to associate a shared library with an application.

Overview

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

Procedure

1. Click Applications > Enterprise Applications > application_name > Shared library references in the console navigation tree to access the Shared library references page.

2. On the Shared library references page, select an application or module to which you want to associate a shared library.

3. Click Reference shared libraries.

4. On the Shared Library Mapping page, select one or more shared libraries that the application or modules use in the Available list, click >> to add them to the Selected list, and click OK.

5. Repeat steps 2 through 4 until you define a library reference instance for each shared library that your application or module requires.

6. On the Shared library references page, click OK.

7. Save the changes to the configuration.

Results

The classes are now available to the application or module.

To verify an association between an application and a shared library, examine the application class loader in the Class Loader Viewer. Click Troubleshooting > Class Loader Viewer > module_name > Table View. The classpath of the application module class loader lists the classes used by the shared library.
