Class JndiBeanFactoryLocator

java.lang.Object
  org.springframework.beans.factory.access.JndiBeanFactoryLocator

All Implemented Interfaces:

BeanFactoryLocator

Direct Known Subclasses:

ContextJndiBeanFactoryLocator

public class JndiBeanFactoryLocator

extends Object

implements BeanFactoryLocator

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

This default implementation creates a DefaultListableBeanFactory, populated via an XmlBeanDefinitionReader. Subclasses may override createFactory for custom instantiation.

Method Detail

useBeanFactory

public BeanFactoryReference useBeanFactory(String factoryKey)
                                    throws BeansException

Load/use a bean factory, as specified by a factoryKey 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 subclass) 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

createBeanFactory

protected BeanFactoryReference createBeanFactory(String[] resources)
                                          throws BeansException

Actually create the BeanFactory, given an array of classpath resource strings which should be combined. This is split out as a separate method so that subclasses can override the actual type uses (to be an ApplicationContext, for example).

Parameters:

resources - an array of Strings representing classpath resource names

Returns:

the created BeanFactory, wrapped in a BeanFactoryReference

Throws:

BeansException
