Class WebBootstrap

java.lang.Object
  org.jboss.portal.common.mc.bootstrap.WebBootstrap

All Implemented Interfaces:

java.util.EventListener, javax.servlet.ServletContextListener, org.jboss.kernel.spi.event.KernelEventListener

public class WebBootstrap
extends java.lang.Object
implements javax.servlet.ServletContextListener, org.jboss.kernel.spi.event.KernelEventListener

A kernel bootstrap with a life cycle triggered by the ServletContextListener interface. All beans will be injected as servlet context attributes. The bean xml file must be available as a servlet context resource under the path /WEB-INF/jboss-beans.xml.

A special bean with the name ServletContext is injected in the kernel before the deployment of the beans from the xml file are deployed. Thus it is possible to inject the servlet context as a bean into other beans.

Field Detail

BEANS_RESOURCE_LOCATION_KEY

public static final java.lang.String BEANS_RESOURCE_LOCATION_KEY

The servlet context init parameter name for the bean resource location. For instance for a web application resource it could be /WEB-INF/my-beans.xml, for the web application classloader resource it could be org/jboss/portal/my-beans.xml. If no init parameter is declared then the litteral value /WEB-INF/jboss-beans.xml is used and the lookup is done in the servlet context resourcees.

BEANS_RESOURCE_TYPE_KEY

public static final java.lang.String BEANS_RESOURCE_TYPE_KEY

The servlet context init parameter name for the bean resource type which can be the servlet context or the web application classloader. If no value is specified the servlet context will be used for resource lookup. The legal values are context for the servlet context and classloader for the web application classloader.
