Class loader ID

Provides a string that is unique to the server identifying the class-loader instance. The product assigns the identifier.

Data type

String

Class loader mode

Specifies the class-loader mode when the application class-loader policy for the application server is Single.

You specify a policy of Single on the settings page for the application server, accessed by clicking Servers > Application Servers > servername. When the policy is Single, applications are not isolated from each other. A single application class loader contains all of the EJB modules, dependency JAR files, and shared libraries in the system.

The Parent First value causes the class loader to delegate the loading of classes to its parent class loader before attempting to load the class from its local class path.

The Parent Last value causes the class loader to attempt to load classes from its local class path before delegating the class loading to its parent. Specifying the Parent Last value enables an application class loader to override and provide its own version of a class that exists in the parent class loader.
