I want to  initialize something using ServletContext before AfterBeanDiscovery.

For example i want start spring container before cdi start up and voted some spring bean in Extension.

I changed some code in WeldServletLifecycle.java

eg:

boolean initialize(ServletContext context) {

   if (isBootstrapNeeded) {

        ............

        //bootstrap.startInitialization();      //////// splite startInitialization into beforeStartInitialization and afterStartInitialization

        bootstrap.beforeStartInitialization();

         ...................................

        manager.fireEvent(new BeforeInitContainerObjectHold(context));/////define a BeforeInitContainerObjectHold and fire. BeforeInitContainerObjectHold  hold a Object type so it can used for SE environment to hold any object

       bootstrap.afterStartInitialization();

   }

}

It work for me.
