J2EE

See the figure below to see J2EE application server sample class loader hierarchy. As it has been shown in the diagram, “system class path” class loaders are parents of specific class loaders. If parent class loaders are present above “system class path” in hierarchy it means child class loaders have visibility to those classes that have been loaded by parents. However, when a parent class loader is present below “system-Class path” child class loaders will have visibility only into those classes that are loaded by parents if they are specified explicitly in manifest file of child class loader.
