[jboss-user] [Installation, Configuration & DEPLOYMENT] - Exception sending context initialized event to listener inst

Hi, I am trying to deploy an application that is using toplink, that's why xmlparserv2.jar is required so I added, when deploying an error appears: 2009-05-25 13:03:18,237 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/MiraWeb]] (HDScanner) Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener java.lang.ClassCastException: oracle.xml.jaxp.JXSAXParserFactory at javax.xml.parsers.SAXParserFactory.newInstance(SAXParserFactory.java:107) at com.sun.faces.config.ConfigureListener$WebXmlProcessor.getConfiguredFactory(ConfigureListener.java:698) at com.sun.faces.config.ConfigureListener$WebXmlProcessor.scanForFacesServlet(ConfigureListener.java:670) at com.sun.faces.config.ConfigureListener$WebXmlProcessor.(ConfigureListener.java:644) at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:156) I found this error on some forums but no response is given. I am not using any JSF implementation, I am using struts 2 so I don't know why this error is happining. any idea?
