Class BootstrapWebApplicationContextListener

java.lang.Object

org.openspaces.pu.container.jee.context.BootstrapWebApplicationContextListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public class BootstrapWebApplicationContextListener
extends Object
implements javax.servlet.ServletContextListener

Bootstap servlet context listener allowing to get the ClusterInfo, BeanLevelProperties, and handle an optional pu.xml file within META-INF/spring by loading it.

The different web containers support in OpenSpaces will use prepareForBoot(java.io.File, org.openspaces.core.cluster.ClusterInfo, org.openspaces.core.properties.BeanLevelProperties) before the web application is started. It will basically marshall the ClusterInfo and BeanLevelProperties so they can be read when the contextInitialized(javax.servlet.ServletContextEvent) is called. It will also change the web.xml in order to add this class as a context listener.

During context initialization, the marshalled ClusterInfo and BeanLevelProperties can be read and put in the servlet context (allowing us to support any web container).

If there is a pu.xml file, it will be started as well, with the application context itself set in the servlet context (can then be used by the ProcessingUnitContextLoaderListener as well as all its beans read and set in the servlet context under their respective names.
