public class ServletSessionPoolManager

extends SessionPoolManager

This class is a servlet-specific session pool manager. It manages a collection of one or more session pools of class ServletSessionPool. This class provides methods that are used to create both the ServletSessionPoolManager itself and the session pools that it contains. These methods are part of the administrative API for a session pool.

When session pools are being used with BEA WebLogic, configuration is done via the BEA WebLogic system properties file and the BEA WebLogic management console. A user does not need to access the adminstrative API directly. Refer to the BEA WebLogic Administrators Guide for information on configuring a ServletSessionPoolManager in a BEA WebLogic environment.

The createSessionPool method on this class creates a servlet-specific session pool of class ServletSessionPool. The getSessionPool method returns a servlet-specific session pool of class ServletSessionPool. The return from getSessionPool should be cast to ServletSessionPool to use the servlet-specific methods as follows:

 ServletSessionPoolManager mgr;
 ServletSessionPool pool;
 
 // ...Assume mgr is retrieved via JNDI.
 
 // Get the ServletSessionPool from the ServletSessionPoolManager
 pool = (ServletSessionPool) mgr.getSessionPool("mypool");
 

Refer to the base class bea.jolt.pool.SessionPoolManager for information about session pools in general.
