Class loader collection
Use this page to manage class-loader instances on an application server. A class loader determines whether an application class loader or a parent class loader finds and loads Java™ class files for an application.
To view this administrative console page, click
.Class loader ID
Specifies a string that is unique to the server identifying the class-loader instance. The product assigns the identifier.
Class loader order
Specifies whether the class loader searches in the parent class loader or in the
application class loader first to load a class. The standard for development kit class loaders and
WebSphere® Application Server class loaders is Classes loaded with
parent class loader first
(Parent first
). By specifying Classes
loaded with local class loader first (Parent last)
, your application can override classes
contained in the parent class loader, but this action can potentially result in ClassCastException
or LinkageErrors if you have mixed use of overridden classes and non-overridden classes.
