Class WebApplicationContextUtils

java.lang.Object
  org.springframework.web.context.support.WebApplicationContextUtils

public abstract class WebApplicationContextUtils
extends Object
extends Object

Convenience methods to retrieve the root WebApplicationContext for a given ServletContext. This is e.g. useful for accessing a Spring context from within custom web views or Struts actions.

Note that there are more convenient ways of accessing the root context for many web frameworks, either part of Spring or available as external library. This helper class is just the most generic way to access the root context.
