Method Detail

loadParentContext

protected org.springframework.context.ApplicationContext loadParentContext(javax.servlet.ServletContext servletContext)
                                                                    throws org.springframework.beans.BeansException

loadParentContext in class org.springframework.web.context.ContextLoader

Parameters:

servletContext - Servlet context for whom load parent context

Returns:

The Join bootstrap context.

Throws:

org.springframework.beans.BeansException

Instantiate the root WebApplicationContext for this loader, ie a XmlWebApplicationContext.

This implementation expects custom contexts to implement ConfigurableWebApplicationContext. Can be overridden in subclasses.

Overrides:

createWebApplicationContext in class org.springframework.web.context.ContextLoader

Parameters:

servletContext - current servlet context

parent - the parent ApplicationContext to use, or null if none

Returns:

The newly created Join web application context

Throws:

org.springframework.beans.BeansException - if the context couldn't be initialized

addingExtraConfigLocationAllowed

protected boolean addingExtraConfigLocationAllowed()

Check if some extra configuration files locations should be added to the default one. This is a hook for subclasses to specifiy their adding criteria. This implementation return true if this context is one the asynchronous side of the application (so that asynchronous applicative services may be started)

Returns:

True if we are on asynchronous side of the application, false otherwise.
