Class ProcessingUnitContextLoader

java.lang.Object

org.springframework.web.context.ContextLoader

org.openspaces.pu.container.jee.context.ProcessingUnitContextLoader

public class ProcessingUnitContextLoader
extends org.springframework.web.context.ContextLoader

Same as Spring ContextLoader. Different in two aspects:

The first, it automatillcay loads the binded META-INF/spring/pu.xml (binded into the servlet context) as the parent application context. See loadParentContext(javax.servlet.ServletContext).

Second, it overrides the creation of WebApplicationContext and automatically adds ClusterInfo and BeanLevelProperties handling. It also delegates the objects to the web context level Spring application context.
