ClassLoader Reference Viewer 

Definition

The class loader references can be viewed easily using the ClassLoader Viewer Service. This service graphically displays the relations between different loaders on a selected cluster element.

Use

The ClassLoader Viewer provides a Runtime tab that enables you to browse easily between the elements. You can view all registered class loaders and the full path to their resources. The loader’s resources are shown in a tree view on the left-hand side of the Runtime tab, together with their short names. The class loaders are displayed in a tree view separated in several groups: Interfaces, Libraries, Services, Applications, and Commons.

The Commons group contains a list of common@ <x> sub-nodes, each representing a different reference cycle.

The references are visualized on the right-hand side of the Runtime tab in the sequence in which they are loaded. This can be useful, for example, if you are tracing an application (if there are similar classes in two different JAR files, you can see which one it is loaded from).

The tree with the available class loaders is not refreshed automatically. To obtain the last registered loaders from the ClassLoader Manager, use  with the quick info text Refresh Tree.

The ClassLoader Viewer also enables a remote interface to be exported to the ClassLoader Manager. For more information, see Working with the Reference Viewer.
