I have deployed a JAXMServlet (of jaxm-api.jar) on jboss-4.0.2. I am using jdk1.5 and bundling the Sun's saaj APIs with the app. I looked at all the xerces APIs and they all have the getSchema () methods. Not sure what the problem is. Help is highly appreciated. I get the following exception

java.lang.NoSuchMethodError: javax.xml.parsers.SAXParserFactory.getSchema()Ljava
