JSFUnitFacesContextFactory incompatible with javax.faces.context.FacesContextFactory
I am using JSF1.2 with Websphere6.1. Place jsf-api in WEB-Inf lib folder. When I place all JSFUnit related jars in WEB-Inf lib folder, validation failed for web module & not able to deploy in Websphere6.1 server. And I tried by placing all the JSFunit Jars in shared library it throws below exception while accessing the application through browser. I am stuck up here for 2 days. Any idea on this?????
java.lang.ClassCastException: org.jboss.jsfunit.context.JSFUnitFacesContextFactory incompatible with javax.faces.context.FacesContextFactory
