Java Class Loader Viewer 

Use

You can use the Java Class Loader Viewer in SAP NetWeaver Administrator to monitor the hierarchy of the class loaders in AS Java.

Features

The Java Class Loader Viewer provides the following features:

●      Display of all class loaders currently available in the system.

●      Options to display class loaders of a specific type only (application, interface, library, service).

●      Display of the relations between the class loaders in the system – parent class loaders, child class loaders, and resources.

●      Search by name for a class loader’s parent, child, or resource.

Activities

●      To access the Java Class Loader Viewer, in SAP NetWeaver Administrator, choose the Problem Management tab.

●      To display all class loaders in the system, from the Show dropdown list box, choose All.

●      To display the class loaders grouped according to their type (application, interface, library, service, or common) use the Show dropdown list box. The result in the Class Loaders list changes according to the selected option.

●      To display parents, children or resources of a class loader, select that class loader from the Class Loaders list. The parent, child and resource class loaders are displayed in the corresponding tabbed page that appears below the Class Loaders list. These class loaders are active and by selecting each of them, you can display its class loader references accordingly.

●      To search for a class loader in the Parents, Children, or Resources list, use the filter field on the top of each list. Enter the name or part of the name of the required class loader and press ENTER.

You can also use shell commands to monitor the hierarchy of the class loaders. More information: Troubleshooting: Finding Missing Parent-Child Relations
