Class GlobalContextManager

java.lang.Object

org.apache.xbean.naming.global.GlobalContextManager

All Implemented Interfaces:

InitialContextFactory, ObjectFactory

Direct Known Subclasses:

javaURLContextFactory

public class GlobalContextManager
extends Object
implements ObjectFactory, InitialContextFactory

The GlobalContextManager contains the static global context object. JNDI effectively requires a single global static to resolve the root context, and this class manages that static. This class is also an URLContextFactory and an InitialContextFactory which returns the registered global context. To use this factory simply set the following system property or pass the property in the environment to new InitialContext: java.naming.factory.initial = org.apache.xbean.naming.global.GlobalContextManager
