类 ServletContextSingleton

java.lang.Object
  org.apache.struts2.config.ServletContextSingleton

public class ServletContextSingleton
extends Object

This singleton holds an instance of the web servlet context.

This is needed for running Struts on Weblogic Server 6.1 because there is no provision to retrieve the servlet context from the web session object.

This class is created to bet that this singleton can be set by FilterDispatcherCompatWeblogic61 before the servlet context is needed by org.apache.struts2.lifecycle.SessionLifecycleListener which will use this object to get it.
