org.springframework.context.access
Class ContextJndiBeanFactoryLocator

java.lang.Object
  org.springframework.jndi.JndiAccessor
      org.springframework.jndi.JndiLocatorSupport
          org.springframework.context.access.ContextJndiBeanFactoryLocator

All Implemented Interfaces:: BeanFactoryLocator

public class ContextJndiBeanFactoryLocator
extends JndiLocatorSupport
implements BeanFactoryLocator
extends JndiLocatorSupport
implements BeanFactoryLocator

BeanFactoryLocator implementation that creates the BeanFactory from one or more classpath locations specified in a JNDI environment variable.

This default implementation creates a ClassPathXmlApplicationContext. Subclasses may override createBeanFactory for custom instantiation.

Method Detail

useBeanFactory

public BeanFactoryReference useBeanFactory(String factoryKey)
                                    throws BeansException

Load/use a bean factory, as specified by a factory key which is a JNDI address, of the form java:comp/env/ejb/BeanFactoryPath. The contents of this JNDI location must be a string containing one or more classpath resource names (separated by any of the delimiters ',; \t\n' if there is more than one. The resulting BeanFactory (or ApplicationContext) will be created from the combined resources.

Specified by:: useBeanFactory in interface BeanFactoryLocator

Parameters:: factoryKey - a resource name specifying which BeanFactory the BeanFactoryLocator should return for usage. The actual meaning of the resource name is specific to the actual implementation of BeanFactoryLocator.
Returns:: the BeanFactory instance, wrapped as a BeanFactoryReference object
Throws:: BeansException - if there is an error loading or accessing the BeanFactory
See Also:: createBeanFactory(java.lang.String[])

createBeanFactory

protected BeanFactoryReference createBeanFactory(String[] resources)
                                          throws BeansException

Create the BeanFactory instance, given an array of class path resource Strings which should be combined. This is split out as a separate method so that subclasses can override the actual BeanFactory implementation class.

Delegates to createApplicationContext by default, wrapping the result in a ContextBeanFactoryReference.

Parameters:: resources - an array of Strings representing classpath resource names
Returns:: the created BeanFactory, wrapped in a BeanFactoryReference (for example, a ContextBeanFactoryReference wrapping an ApplicationContext)
Throws:: BeansException - if factory creation failed
See Also:: createApplicationContext(java.lang.String[]), ContextBeanFactoryReference

createApplicationContext

protected ApplicationContext createApplicationContext(String[] resources)
                                               throws BeansException

Create the ApplicationContext instance, given an array of class path resource Strings which should be combined

Parameters:: resources - an array of Strings representing classpath resource names
Returns:: the created ApplicationContext
Throws:: BeansException - if context creation failed
