Enterprise application topology
See where modules reside in a topology of enterprise applications. Knowing where a module resides helps you to determine which class loader loaded a module and to diagnose problems with class loaders.
From the admin console, click Troubleshooting > Class loader viewer
This page lists all installed applications and their modules in a tree view. The modules can be web modules (.war files) or EJB modules (.jar files).
When deploying an application to a server or starting an application, we might encounter problems related to class loaders. Use the console pages accessed from this page to troubleshoot errors such as the following:
- ClassCastException
- ClassNotFoundException
- NoClassDefFoundException
- UnsatisfiedLinkError
Use the Class loader viewer console pages without having to restart or manipulate the application.
Enterprise applications topology
Display a tree hierarchy of applications installed on a server and lists the module files in the class paths of the applications.
Expand the hierarchy for an application to see what web modules (.war files) and EJB modules (.jar files) are in the application class path.
Click on a module name to examine the class loaders of the module.
