    issues integrating seam and facelets to myfaces, spring and hibernate app

      Please I need help
      I have issues integrating seam and facelets to myfaces, spring and hibernate app. Config details and error below.

      The combination Hibernate 3.4  + Spring 2.5.5 + Myfaces 1.2.5 was already working. And I included the jars:
      Facelets 1.1.14: jsf-facelets.jar, el-api-1.0.jar, el-impl-1.0.jar
      Seam 2.1.1: jboss-seam.jar, jboss-seam-ui.jar, persistence-api.jar, javaassist.jar

      [b]ERROR:[/b]
      Jan 15, 2009 11:35:31 AM org.apache.catalina.core.StandardContext listenerStart
      SEVERE: Exception sending context initialized event to listener instance of class org.apache.myfaces.webapp.StartupServletContextListener
      java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, org/apache/myfaces/webapp/Jsp21FacesInitializer, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ELResolver used in the signature

      Since tomcat 6 has el-api.jar I tried removing el-api and el-impl jars from facelets. and I still didn't work. I tried replcing them with jboss-el still same thing; also replaced with el-api jar shipped with seam and still didn't work. If I remove el-api from tomcat lib I get a classNotFound exception.

      I have spent a long time trying to figure it out. I would really appreciate your help.
      Thanks
