of a Cluster is 
org.apache.catalina.Cluster implementations
of this class is done when implementing a new Cluster protocolThis package contains

various supported realm technologies for authenticating users and
identifying their associated roles.This package contains 
Servlets that implement some of the
standard functionality provided by the Catalina servlet container.This package contains the standard 
Manager and
Session implementations that represent the collection of

that are associated with a Context.This package contains code that is used by the SsiInvoker.
QuickStart
This package contains a variety of small Valve implementations that do
not warrant being packaged separately.
