Class ExternalContextUtils

java.lang.Object
  org.apache.myfaces.commons.util.ExternalContextUtils

public final class ExternalContextUtils
extends Object

This provides some functionality for determining some things about the native request object that is not provided by JSF. This class is useful for use in places where Portlet API's may or may not be present and can also provide access to some request-specific items which are not available on the JSF ExternalContext. If portlet API's are not present, this class simply handles the Servlet Request type.
