Examples of org.apache.jetspeed.om.registry.PortletEntry

org.apache.jetspeed.om.registry.PortletEntry
This entry describes all the properties that should be present in a RegistryEntry describing a Portlet.
Each PortletEntry must have a type, which may be:

abstract
The entry description is unsuitable for instanciating a Portlet

instance
This entry may be used to create a Portlet and does not depend on any other portlet entries

ref
This entry may be used to instanciate Portlets but depends on another PortletEntry definition whose registry name can be retrieved by getParent()
