    Making JSF jars into a separate JBoss Module

    Devikumar R Newbie

      The goal is to move the JSF related jars in the Web app /lib folder to a custom module, so that this can be shared across other applications.

      Server : JBoss EAP 6

      Portal Framework : Liferay

       

      After deleting the JSF jars from WEB-INF\lib and moving to modules,


      1. Caused by: java.lang.NoClassDefFoundError: javax/el/CompositeELResolver

          at java.lang.ClassLoader.defineClass1(Native Method) [rt.jar:1.6.0_30]

      The issue now is :


      getBridge().init(portletConfig);, init(PortletConfig portletConfig) -- GenericFacesPortlet.class - getBridge() returns com.liferay.faces.bridge.BridgeImpl


      BridgeImpl.init(portletConfig) -- bridgePhaseFactory = (BridgePhaseFactory) BridgeFactoryFinder

                      .getFactory(com / liferay / faces / bridge / BridgePhaseFactory);


      getInstance().getFactoryInstance(clazz) -- getInstance() returns BridgeFactoryFinderImpl


      BridgeFactoryFinderImpl.getFactoryInstance returns null.


      As bridgeFactoryCache.get("com / liferay / faces / bridge / BridgePhaseFactory") is null when we remove the jsf jars from lib in WAR. When it is present in war, it is having the value.


      We get bridgeFactoryCache  from bridgeFactoryCache = (Map) portletContext.getAttribute("com.liferay.faces.bridge.bridgeFactoryCache");


      Because of this, we get the following Null Pointer Exception


      15:20:44,305 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/business].[loginPortlet Servlet]] (http-localhost-127.0.0.1-8080-3) Servlet.service() for servlet loginPortlet Servlet threw exception: java.lang.NullPointerException

      Could you please suggest what has gone wrong or what has to be done to successfully make JSF jars into a module?
