    ClassCastException: org.jboss.seam.jsf.SeamApplication11 inc

    Denis Forveille Novice

      Hello,
      I'm trying to setup a project with seam 1.2.1 on WebSphere v6.1.0.7.

      WAS v6.1.0.7 has a JSF 1.1 implementation based on JSF Sun RI. When WAS tries to start the application, I get the following exception:

      WebApp E Extension processor failed to initialize in factory: com.ibm.ws.jsf.extprocessor.JSFExtensionFactory@cd60cd6
      java.lang.ClassCastException: org.jboss.seam.jsf.SeamApplication11 incompatible with com.sun.faces.application.ApplicationImpl
      at com.ibm.ws.jsf.configuration.FacesConfigParser.createFacesFactories(FacesConfigParser.java:1019)
      at com.ibm.ws.jsf.configuration.FacesConfigParser.initializeConfiguration(FacesConfigParser.java:354)
      at com.ibm.ws.jsf.util.FacesConfigUtil._parseJSFConfiguration(FacesConfigUtil.java:128)
      at com.ibm.ws.jsf.util.FacesConfigUtil.parseJSFConfiguration(FacesConfigUtil.java:82)

      at com.ibm.ws.jsf.configuration.FacesConfig.initialize(FacesConfig.java:96)

      Q:
      - Any idea for this exception (I'v tried lots of things to try to have it working, including playing with classloader...)
      - What is the requirement for seam on JSF: Does seam absolutely requires "MyFaces" as JSF implementation? or can I use WAS JSF 1.1 implementation bases on Sun RI? or more generally any JSF 1.1 compatible implementation?
      - Anyone there running seam 1.2.1 on WAS v6.1.0.7 with the builtin JSF implementation?
      thx
